1........H3 PO4 + Mg (OH)2 => Mg3 (PO4)2 + H2O
2........NH4 OH +H3 PO4 => (NH4)3 PO4 + H2O
3........Ca3 (PO4)2 + Si O2 + C => Ca Si O3 + CO + P

✔ 最佳答案
Balanced:2 H3 PO4 + 3 Mg(OH)2 => Mg3 (PO4)2 + 6 H2O
3 NH4 OH +H3 PO4 => (NH4)3 PO4 + 3 H2O
Ca3 (PO4)2 + 3 Si O2 + 4 C => 3 Ca Si O3 + 4 CO + 2 P

Sorry my bad on number 3...the correct answer should be 5 C on the left side and 5 CO on the right side.
