SEE EXPLANATION
Explanation:
A)
1) The balanced chemical reaction is;
Fe2O3 + 3H2O> 2Fe(OH)3
2) C12H22O11> 12 C + 11H2O
B) 1 is a combination reaction
2 is a decomposition reaction
C) The molar mass of NH3 is 14 + 3(1) = 17 g/mol
Percentage composition of N = 14/17 * 100/1 = 82. 4 %
D) 1 mole of O2 contains 6.02 * 10^23 particles
E) For (NH4)3 PO4
We have 3(14 + 4(1)) + 31 + 4(16) = 149 g/mol
F) 1 mole of CaCO3 contains 100g of CaCO3
1.25 moles of CaCO3 contains 1.25 * 100/1 = 125 g of CaCO3
