Responses

There will be 2 moles of sodium (Na) in the product.
There will be 2 moles of sodium (Na) in the product.

There will be two molecules in the product.
There will be two molecules in the product.

There will be 1 mole of silver (Ag) in the product.
There will be 1 mole of silver (Ag) in the product.

There will be five atoms in the product.

Answer 1

There will be 1 mole of silver (Ag) in the product.

Explanation: AgNO3 + NaCl → AgCl + NaNO3. Conservation of mass (and atoms) means the 1 mole of Ag in the reactants appears as 1 mole of Ag in the products (in AgCl).
