Question

Ba(NO3)2 + 2LiOH → Ba(OH)2 + 2LiNO3

How many nitrate ions are in the products and the reactants of the chemical equation?
A.
one in the reactants and two in the products
B.
three in the reactants and three in the products
C.
two in the reactants and two in the products
D.
six in the reactants and three in the products

Answer 1

C.

two in the reactants and two in the products

Step-by-step explanation:

The law of conservation of mass helps us balance chemical equations so that there are the same number and type of atoms in the reactants and products.

There are two nitrate ions in Ba(NO3)2 and two in 2LiNO3.
