Answer:
c=2
Explanation:
Chemical equation:
Ca(OH)₂(aq) + HCl (aq) → CaCl₂(aq) + H₂O
Balanced chemical equation:
Ca(OH)₂(aq) + 2HCl (aq) → CaCl₂(aq) + 2H₂O
This is an acid-base reaction.
Two mole of acid (HCl) react with one mole of base (Ca(OH)₂) and form two mole of water and one mole of salt which is calcium chloride.
The given reaction also follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Acid-Base Reaction.
Whenever an acid react with base salt and water is formed. Acid-base reaction is also called neutralization reaction.
