A reaction occurs between sodium carbonate and hydrochloric acid producing sodium chloride, carbon dioxide, and water. The correct set of coefficients, respectively, for the balanced reaction is:

The correct set of coefficients are 1, 2 ,2 ,1 and 1 , respectively,  for sodium carbonate , hydrochloric acid , sodium chloride, carbon dioxide, and water

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced reaction for sodium carbonate and hydrochloric acid producing sodium chloride, carbon dioxide, and water is:

The correct set of coefficients, respectively, for the balanced reaction is 1, 2 ,2 ,1 and 1 respectively for sodium carbonate , hydrochloric acid , sodium chloride, carbon dioxide, and water

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
