Word Equation Examples
As a word equation or as “Hydrogen and oxygen react to form water” or “Water is made by reacting hydrogen and oxygen.”More examples of word reactions include: Chlorine gas reacts with methane and carbon tetrachloride to produce hydrogen chloride.

What is the word equation and how it is written?

A word equation should state the reactants (starting materials), products (ending materials), and direction of the reaction in a form that could be used to write a chemical equation. ex: Cu + O2 → CuO. diavinad8 and 99 more users found this answer helpful.

How do you write an equation for an element in word?

Go to the insert tab. Click on the equation button on the far right. Here are also shortcut commands to render most common things. For example, underscore _ creates a subscript and a caret ^ creates a super script.

How do you write symbol equations?

A balanced symbol equation has the same number of atoms of each element on both sides of the arrow. To balance an equation, add numbers to the left of one or more formulae.
Balancing an equation.

What is Word equation give one example class 10?

Hint: Word equation means we have to write the chemical reaction in the form of words. Chemical reaction means we have to mention the chemical symbols of the elements to represent the reaction. Nail contains iron in it. The molecular formula of copper sulphate is CuSO4.

What is simple equation?

A simple equation refers to a mathematical equation that expresses the relationship between two expressions on both sides of the ‘equal to’ sign. This category of an equation consists of a variable, usually in the form of x or y. Solving simple equations often require rearranging it.

What do you mean by formula equation?

A “formula” is generally a equation of form y=f(a, b, c) given for the purpose of calculating the value of the dependent variable (y in this case) given the values of the independent variables (a, b, and c in this case).

How do you write math equations in Word Online?

Click on the Insert tab on the ribbon. Click on Equation. Use the Math Symbols section to browse common mathematical characters and operators. Click on a symbol to insert it into your equation.

How do you write an Equation from a word problem?

Here are some steps to follow:

1. Understand the problem. Understand all the words used in stating the problem. Understand what you are asked to find.
2. Translate the problem to an equation. Assign a variable (or variables) to represent the unknown.
3. Carry out the plan and solve the problem.

How many words can you make from the word equation?

109 words can be made from the letters in the word equation.

Is word equation is a balanced chemical equation?

Answer: Formula of a reactant or product cannot be altered, but chemical equation is balanced by multiplying the reactant or product with numbers like 2,3,4,5 and so on to balance the number of atoms in the chemical equation.

How is a word equation useful?

Word equations are useful to show which chemicals react together (the reactants) and which chemicals are produced (the products). Symbol equations allow chemists to work out the masses that will react or be produced.

What is word equation class 10th?

A word equation is a chemical reaction expressed in words rather than chemical formulas.

Are formulas equations?

A formula is an equation that shows the relationship between two or more quantities. It would be the rule or instructions that is use to show the relationship between two or more quantities.

What is the word equation for 2H2 O2 → 2H2O?

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

What is the difference between a word equation and a formula equation?

A word equation uses words to represent the reactants and products in a chemical reaction. A formula equation uses chemical symbols or formulas, but does not reveal the ratios of the products and reactants.

What are the 6 types of reactions?

Six common types of chemical reactions are: synthesis, decomposition, single-displacement, double-displacement, combustion and acid-base reactions. Scientists classify them based on what happens when going from reactants to products.

In chemistry, a word equation is a chemical reaction expressed in words rather than chemical formulas. A word equation should state the reactants (starting materials), products (ending materials), and direction of the reaction in a form that could be used to write a chemical equation.

There are some key words to watch for when reading or writing a word equation. The words «and» or «plus» mean one chemical and another are both reactants or products. The phrase «is reacted with» indicates the chemicals are reactants. If you say «forms», «makes», or «yields», it means the following substances are products.

When you write a chemical equation from a word equation, the reactants always go on the lefthand side of the equation, while the reactants are on the righthand side. This is true even if the products are listed before the reactants in the word equation.

Word Equation Examples

The chemical reaction 2 H₂(g) + O₂(g) → 2 H₂O(g) would be expressed as:

hydrogen gas + oxygen gas → steam
As a word equation or as «Hydrogen and oxygen react to form water» or «Water is made by reacting hydrogen and oxygen.»

While a word equation doesn’t ordinarily include numbers or symbols (Example: You wouldn’t say «Two H two and one O two makes two H two O», sometimes it is necessary to use a number to indicate the oxidation state of a reactant so that a person writing a chemical equation can do it correctly. This is mostly for the transition metals, which can have multiple oxidation states.

For example, in the reaction between copper and oxygen to form copper oxide, the chemical formula of copper oxide and the number of copper and oxygen atoms involved depends on whether copper(I) or copper(II) participates in the reaction. In this case, it would be fine to say:

copper + oxygen → copper(II) oxide

or

Copper reacts with oxygen to produce copper two oxide.

The (unbalanced) chemical equation for the reaction would start out as:

Cu + O₂ → CuO

Balancing the the equation yields:

2Cu + O₂ → 2CuO

You would get a different equation and product formula using copper(I):

Cu + O₂ → Cu₂O

4Cu + O₂ → 2Cu₂O

More examples of word reactions include:

• Chlorine gas reacts with methane and carbon tetrachloride to produce hydrogen chloride.
• Adding sodium oxide to water produces sodium hydroxide.
• Iodine crystals and chlorine gas react to make solid iron and carbon dioxide gas.
• Zinc and lead two nitrate make zinc nitrate and lead metal.
  which means: Zn + Pb (NO₃)₂ → Zn(NO₃)₂ + Pb

Why Use Word Equations?

When you’re learning general chemistry, work equations are used to help introduce the concepts of reactants, products, the direction of reactions, and to help you understand precision of language. They may seem annoying, but are a good introduction to the thought processes required for chemistry courses. In any chemical reaction, you need to be able to identify the chemical species that react with each other and what they make.

Word Equations in Other Sciences

Chemistry isn’t the only science to use equations. Physics equations and mathematical equations may also be expressed in words. Usually in these equations two statements are set to be equal to each other. For example, if you way «force equals mass multiplied by acceleration» then you are providing the word equation for the formula F = m*a. Other times, one side of the equation may be less than (<), greater than (>), less than or equal to, or greater than or equal to the other side of the equation. Addition, subtraction, multiplication, division, logs, square roots, integrals, and other operations can be stated in word equations. However, complex equations that contain parentheses to describe the order of operations are very hard to understand as word equations.

A student asked me about using LaTeX the other day, and I stated that it is a bit of a hassle for journal articles in our field, so I have begun to use it less. Most of the journals in my field (criminology and criminal justice) make it difficult to turn in an article in that format. Many refuse to accept PDF articles outright, and last time I submitted a LaTeX file to JQC (a Springer journal) that would not compile I received zero help from staff over a month of emails, so I just reformatted it to a Word document anyway. Last time I submitted a LaTeX document to Criminology a reviewer said it probably had typos — without pointing out any of course. (FYI folks, besides doing the obvious and pointing out typos if they exist, my text editor has a spell checker same as Word to highlight typos.) Besides this, none of my co-workers use LaTeX, so it is a non-starter for when I am collaborating. I did my dissertation in LaTeX, and I would do that in LaTeX again, but smaller articles are not a big deal.

The main nicety of LaTeX are math equations. I don’t do too heavy of math stuff, and I have figured out the Microsoft Word equation editor enough to suit most of my needs. So here are a set of examples for many of the use cases I have needed to use in journal articles. I also have this in a Word (docx) document and a PDF for handy reference. Those have a few references I gathered from the internet, but the best IMO is this guys blog (who I think is a developer for Word) and this document authored by the same individual.

One of the things to note about the equation editor in Word is that you can type various shortcuts and then they will be automatically converted. For example, you can type gamma, hit the space bar, and then the equation will actually change to showing the gamma symbol. So there are some similarities to LaTeX. (Another pro-tip, to start an equation in Word you can press Alt=.) In the subsequent examples I will use <space> to represent hitting the space bar, and there are other examples of using <back> (for the left arrow key) and <backspace> for the backspace button.

Greek characters, subscripts and superscripts

If you type

log<space>(lambda) = beta_0<space> + beta_1<space>(X) + beta_2<space>(X^2<space>)

you get:

Accents

For these you need to hit the space key twice, so

xhat<space><space> = ybar<space><space>

turns into:

Expected value and variance

For the equivalent of mathbb in LaTeX, you can do

doubleV<space>(X)= doubleE<space>(X)^2<space> + doubleE<space>(X^2<space>)

Plain text within equation

To do plain text within an equation, equivalent to text{*} in LaTeX, you can use double quotes. (Note that you do not need a backslash before “log”.) So

Y = -1cdot<space>log<space>("Property Crime"<space>) + (not pretty text)

looks like:

Sum and product

To get the product symbol is simply prod<space>, and here is a more complicated example for the sum:

n^-1cdot<space>sum^n_(i=1)<space>x_i<space>= xbar<space><space>

Square root

Square roots always cause me trouble for how they look and kern (both in LaTeX and Word). Here is how I would do an example of Euclidean distance,

d_ij<space>=sqrt<space><space><back>(x_i-x_j)^2+(y_i-y_j)^2<space>

Fractions

The big (stacked) fraction is simple, but I had to search for a bit to find how to do inline fractions (what Word calls “linear”). So here back slash followed by forward slash does the inline fraction:

1/n = 1/n

Numbering an equation

I’ve seen quite a few different hacks for numbering equations in Word. If you need to number and refer to them in text often, I would use LaTeX. But here is one way to do it in Word.

E = mc^2#(30)<enter>

produces below (is it just me or does this make the equation look different than the prior ones in Word?):

Multiple lines of equations

For a while I did not think this was possible, but I recently found examples of multiline equations (equivalent to align in LateX). The way this works is you place a & sign before the symbols you want to line up (same as LaTeX), but for Word to split a line you use @. So if you type

eqarray(10x&=4y@5x&=2y)eqarray<space><backspace>

you will get:

Have any more good examples? Let me know in the comments!

The other nicety of LaTeX is formatting references — you are on your own though for that in Word though.
