Question

Sodium chloride reacts with silver nitrate to produce silver chloride and sodium nitrate

(a) Write the equation.

(b) Check whether it is balanced, if not balance it.

(c) Find the weights of reactants and products.

(d) State the law that this equation satisfies.

Answer 1

(a) $NaCl$ + $AgN{O}_3$ → $NaN{O}_3$ + $AgCl$

(b) The number of atoms of reactants and products are same.
So this equation is a balanced equation.

(c) This equation obeys the law of conservation of mass.
That is total mass of reactant = total mass of product.

(d) $NaCl$ + $AgN{O}_3$ → $NaN{O}_3$ + $AgCl$
58.5 + 170 = 85 + 143.5
228.5 g = 228.5 g
