Question

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. A chemical equation is a balanced formula equation.

Answer 1

Answer:

Aluminium + iron9(III)oxide ⇒ aluminium oxide + iron(word equation)

Explanation:

1] A word equation uses words to represent the reactants and products in a chemical reaction. It can be shown by the following example -

Aluminium + iron9(III)oxide ⇒ aluminium oxide + iron (word equation)

2] A formula equation uses chemical symbols or formulas, but does not reveal the ratios of the products and reactants. It can be shown by the following example -.

$Al_(_s_) + Fe_2O_3_(_s_)$   ⇒   $Al_2O_3_(_s_) + Fe_(s)$ (formula equation)

3] A chemical equation is a balanced formula equation. It can be shown by the following example -            

$2Al_(_s_) + Fe_2O_3_(_s_)$   ⇒   $Al_2O_3_(_s_) + 2Fe_(_s_)$ (chemical equation)
