Gay Lussac’s Law of Combining Volumes states that when gases react, they do so in volumes which bear a simple ratio to one another, and to the volume of the product(s) formed if gaseous, provided the temperature and pressure remain constant.

Answer 2

Gay-Lusac's Law of combining Gas Volumes sates that:

<>The volume of gases taking part in a chemical reaction show simple whole number ratios to one another when those volumes are measured at the same temperature and pressure.

•When gas A reacts with gas B to produce gas C at constant temperature and pressure, then the ratio of the gas volumes will be a simple whole number ratio:

For gaseous reaction at constant temperature and pressure

volume of Gas A : volume of Gas B : volume of Gas C

x : y : z

where x, y and z are all whole numbers

<> For a reaction in which all the reactants and products are gases:

aA(g) + bB(g) → cC(g)

The ratio of the volumes of gasses A, B and C is a:b:c

<>For a reaction in which one of more of the reactants and/or products are NOT gases, then ONLY the volume of gases will be in a simple whole number ratio.
