Answer 1

Ответ:

Объяснение:

Zn + HCl = ZnCl₂ + H₂↑

3K₂O + 2H₃PО₄ = 2K₃PО₄ + 3H₂O

BaO + 2HBr = BaBr₂ + H₂O

4Na + O₂ = 2Na₂O

N₂ + 3H₂ = 2 NH₃

2Cr + 3O₂ = 2CrO₃

Si + O₂ = SiO₂

2Cl₂ + 7O₂ = 2Cl₂O₇

S + H₂ = H₂S

4N + 5O₂ = 2N₂O₅

Zn + Cl₂ = ZnCl₂

4 Li + O₂ = 2 Li₂O

Cr₂O₃ + 6HBr = 2CrBr₃ + 3H₂O

CrBr₃ + 3H₂O = Cr(OH)₃ + 3HBr

Li₂O + 2HI = 2LiI + H₂O

2Li + 2H₂O = 2LiOH + H₂↑

Mg + 2 HF = MgF₂ + H₂↑

4B + 3O₂ = 2B2O₃

4Fe + 3O₂ = 2Fe₂O₃

2Zn + O₂ = 2ZnO

2P + 3H₂ = 2PH₃

2Ca + O₂ = 2CaO

N + O₂ = NO₂

4Br + 5O₂ = 2Br₂O₅

2S + 3O₂ = 2SO₃

4Mn + 7O₂ = 2Mn₂O₇
