Question

In a reaction, 1 moles of silver nitrate combines with 1 mole of sodium chloride
AgNO3 + NaCl
Which statement about the product is justified by the law of conservation of mass?
A. There will be two molecules in the product
B. there will be 2 moles of sodium in the product
C. there will be 1 mole of silver in the product
D. there will be five atoms in the product

Answer 1

C. There will be 1 mole of silver in the product

This is justified by the law of conservation of mass, which states that matter is neither created nor destroyed in a chemical reaction. Since the reactants only contain 1 mole of silver, the product will also contain 1 mole of silver.
