AlPO4 + CO2 + H2O

Question

Find the number of atoms for

Al =
C =
O =
H =
P =

Answer 1

The chemical equation is not balanced. To balance the equation, we must make sure that the number of atoms of each element on both sides of the equation is equal.

The balanced equation is:

AlPO4 + 2 CO2 + 2 H2O -> Al(OH)2(CO3)2 + PO4

Now we can find the number of atoms for each element.

Al = 1 atom
C = 2 atoms (2 CO2 molecules)
O = 8 atoms (6 from 2 CO2 molecules + 2 from H2O molecules)
H = 4 atoms (2 from 2 H2O molecules)
P = 1 atom
