What does the term stoichiometrically equivalent ratio mean, and how it is applied in solving problem?

Short Answer

Expert verified

The definite quantity of one substance that reacts with a definite quantity of all remaining other substanes which can be represented in the form of a chemical equation is known as a stoichiometrically equivalent molar ration.

1). Identification of reactants and products

Example. Magnesium, oxygen, magnesium oxide.

2). Physical states of reactants and products.

Example. (s) solid, (g) gas, (l) liquid and (aq) solution.

3). Mole ratios of raectants and products.

2 moles Mg to 1 mole O₂ to 2 moles MgO.

Step by step solution

Step 1. Considering the following chemical equations:

$2 Mg (s) + O_{2} (g) 鈫� 2 MgO (s)$

Here Mg and O₂ are reactants, MgO is the product and the arrow indicates the direction of the reaction proceed.

Whereas (s) indicates solid, (g) is gas. Also, 2 Mg indicates 2 moles of Mg, and 2 MgO is referred to as 2 moles of MgO.

Step 2. The following points define which types of information does a balanced chemical eqyation provides:

1). Identification of reactants and products

Example. Magnesium, oxygen, magnesium oxide.

2). Physical states of reactants and products.

Example. (s) solid, (g) gas, (l) liquid, and (aq) solution.

3). Mole ratios of raectants and products.

2 moles Mg to 1 mole O₂ to 2 moles MgO.
