Question
In the given reaction, Hydrochloric acid reacts with sodium hydroxide to form sodium chloride and water. The given chemical reaction:
- Does not follow the law of conversation of mass
- In accordance with the law of conversation of mass
- In accordance with the law of reciprocal proportion
- Both (B) and (C)
Hint:
The mass of reactants is equal to the mass of products formed.
The correct answer is: In accordance with the law of conversation of mass
- When Hydrochloric acid reacts with sodium hydroxide the products formed are sodium chloride and water. Say that the weight of reactants was 10gm, then the weight of products will also be 10gm.
- The law of conservation of mass: The mass of an isolated system cannot be created or destroyed, but is transformed from one form to another". The law of conservation of mass states that quantum mechanics and Corrected with the help of special relativity.
