Question

An unbalanced equation is given. Balance the equation. Then add up the coefficients on both sides of this properly balanced equation and identify the total. HINT: when balencing an equation, never change the subscripts.
Al2(CO3)3+H3PO4 -> AlPO4+CO2+H2O
A) 5 B) 8 C) 11 D) 13 An unbalanced equation is given. Balance the equation. Then add up the coefficients on both sides of this properly balanced equation and identify the total. HINT: when balencing an equation, never change the subscripts.
Al2(CO3)3+H3PO4 -> AlPO4+CO2+H2O
A) 5 B) 8 C) 11 D) 13
Al2(CO3)3+H3PO4 -> AlPO4+CO2+H2O
A) 5 B) 8 C) 11 D) 13

Explanation / Answer

Balanced equation

Al2(CO3)3 + 2 H3PO4 = 2 AlPO4 + 3 CO2 + 3 H2O

Sum of stoichiometric coefficient of reactants = 1 + 2 = 3

Sum of stoichiometric coefficient of products = 2 + 3 + 3 = 8

Total sum = 8 + 3 = 11

Option C is the correct answer
