Question

Химические уравнения
P + Cl2 = PCl5
CH4 = C + H2
Na + S = Na2S
HCl + Mg = MgCl2 + H2
ZnSO4 + KOH = K2SO4 + Zn(OH)2
BaCl2 + Na2SO4 = BaSO4 + NaCl
AlCl3 + NaOH = NaCl + Al(OH)3
Fe(OH)3 = Fe2O3 + H2O
H2SO4 + Al = Al2(SO4)3 + H2
P2O5 + Na2O = Na3PO4
Al2(SO4)3 + Ba(NO3)2 = Al(NO3)3 + BaSO4

Answer 1

$2P + 5Cl_{2} = 2PCl_{5}\\CH_{4} = C + 2H_{2}\\Na + S = Na_{2}S\\2HCl + Mg = MgCl_{2} + H_{2}\\ZnSO_{4} + 2KOH = K_{2}SO_{4} + Zn(OH)_{2}\\BaCl_{2} + Na_{2}SO_{4} = BaSO_{4} + 2NaCl\\AlCl_{3} + 3NaOH = 3NaCl + Al(OH)_{3}\\2Fe(OH)_{3} = Fe_{2}O_{3} + 3H_{2}O\\3H_{2}SO_{4} + 2Al = Al_{2}(SO_{4})_{3} + 3H_{2}\\P_{2}O_{5} +3 Na_{2}O = 2Na_{3}PO_{4}\\Al_{2}(SO_{4})_{3} + 3Ba(NO_{3})_{2} = 2Al(NO_{3})_{3} + 3BaSO_{4}$
