# Word and skeletal equations

• caprija
In summary, a word equation is a representation of a chemical reaction using the names of substances, while a skeletal equation is a more concise representation using chemical formulas and symbols. The purpose of balancing a chemical equation is to ensure that the number of atoms of each element is equal on both sides, and this can be done by adjusting coefficients or checking the number of atoms before and after the reaction. Word and skeletal equations can be interchangeable, but skeletal equations are preferred for their concise representation in advanced chemistry.

I was wondering if somebody could check these questions for me:

1. To get cupric hyroxide and cupric carbonate you coerce copper, water, carbon dioxide and oxygen reacting.

Word : copper + water + carbon dioxide + oxygen -----> cupric hydroxide +
cupric carbonate

Skeletal: Cu + H20 + CO2 + O2 ------> OH3 + CO3

I'm not really sure how to do the bolded ones.

Can someone tell me which parts I got right?

The RHS should be $$Cu(OH)_{2}+ CuCO_{3}$$

CuPROUS= Cu(I)

CuPRIC=Cu(II)

Thanks guys

Is the other stuff okay?

yes it is.

## 1. What is a word equation?

A word equation is a way to represent a chemical reaction using the names of the substances involved. It is commonly used in introductory chemistry to help students understand the reactants and products of a reaction.

## 2. What is a skeletal equation?

A skeletal equation, also known as a formula equation, is a more concise representation of a chemical reaction using chemical formulas and symbols. It shows the reactants and products in a more simplified form compared to a word equation.

## 3. What is the purpose of balancing a chemical equation?

The purpose of balancing a chemical equation is to ensure that the number of atoms of each element is equal on both sides of the equation. This follows the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.

## 4. How do you balance a chemical equation?

To balance a chemical equation, you need to adjust the coefficients in front of each substance until the number of atoms of each element is equal on both sides. You can also use the method of checking the number of atoms of each element before and after the reaction to ensure balance.

## 5. Can word and skeletal equations be interchangeable?

Yes, word and skeletal equations can be interchangeable as they both represent the same chemical reaction. However, word equations are more commonly used in introductory chemistry, while skeletal equations are used in more advanced chemistry and are preferred for their concise representation.
