Sodium oxide (na2o) can react with hydrochloric acid (hcl) to produce sodium chloride (nacl) and water (h2o) according to the following equation: na2o + 2hcl -> 2nacl + h2o how many total atoms are present before and after the reaction? a) 2 before and 2 after
b) 3 before and 3 after
c) 5 before and 5 after
d) 7 before and 7 after

D) 7 before and 7 after

Step-by-step explanation:

  Na₂O   +  2HCl    ⟶    2NaCl      +   H₂O

3 atoms + 4 atoms ⟶ 2×2 atoms + 3 atoms

        7 atoms         ⟶    4 atoms   + 3 atoms

        7 atoms         ⟶            7 atoms

There are seven atoms present before and after the reaction.
