The statements for laws of chemical combinations are given below. Mark the statement which is not correct.
  • a)
    Matter can neither be created nor destroyed: Law of conservation of mass
  • b)
    A compound always contains exactly the same proportion of elements by weight: Law of definite proportions
  • c)
    When gases combine they do so in a simple ratio by weight: Gay Lussac's Law
  • d)
    Equal volumes of gases at same temperature and pressure contain same number of molecules: Avogadro's Law
Correct answer is option 'C'. Can you explain this answer?

Law of Conservation of Mass states that matter can neither be created nor destroyed. The total mass, that is, the sum of the mass of the reacting mixture and the products formed remains constant. 
Law of Definite Proportions states that the proportion of elements by weight in a given compound will always remain exactly the same. 
Gay Lussac’s Law of Gaseous Volume states that in a gaseous system, when the reactants combine together they always do so in volumes which bear a simple ratio to one another and to the volume of the products, under similar conditions of temperature and pressure.
Avogadro’s Law states that under the same conditions of temperature and pressure, the equal volume of all the gases contains an equal number of molecules.
Thus statement C is for Law of definite proportion
option C is correct

Explanation:

Laws of Chemical Combinations:
- Law of conservation of mass: Matter can neither be created nor destroyed. This means that the total mass of the reactants in a chemical reaction is equal to the total mass of the products.
- Law of definite proportions: A compound always contains exactly the same proportion of elements by weight. This means that the elements in a compound are always present in fixed proportions by mass.
- Gay Lussac's Law: When gases combine, they do so in a simple ratio by volume, not by weight. Gay Lussac's Law states that the volumes of gases involved in a chemical reaction are in simple whole number ratios to each other.
- Avogadro's Law: Equal volumes of gases at the same temperature and pressure contain the same number of molecules. This law helps in understanding the relationship between volume and the number of molecules present in a gas.
Therefore, the statement "When gases combine they do so in a simple ratio by weight: Gay Lussac's Law" is not correct as Gay Lussac's Law actually deals with the simple ratio by volume, not by weight.
