Question

If the reaction occurs between K2CO3(aq) and Cu(NO3)2(aq) and the equation is properly balanced with the smallest whole-number coefficients, what is the sum of the coefficients for all reactants and products?

Answer 1

Answer: 5

Balanced Reaction:

`1K_2CO_3 + 1Cu(NO_3)_2` ⇒
`2KNO_3 + 1CuCO_3`

When taking the coefficients we are left with 1 + 1 + 2 + 1 = 5
