Question

Закончите уравнение реакций которые только возможны : 1)Ca+H2O= 2)P+O2= 3)CuO+H2= 4)Zn+HCI= 5)H2+O2= 6)H2S+ O2

Answer 1

Са + 2H2O = Ca(OH)2 + H2
P+5O2=2P2O5
CuO + H2 = Cu + H2O
Zn + 2HCI = H2 + ZnCl2.
H2+O2=2H2O
2H2S + 3O2 = 2SO2 + 2H2O

Answer 2

Уравнения реакций:

1) Ca + H2O = ? 2) P + O2 = ? 3) CuO + H2 = ? 4) Zn + HCl = ? 5) H2 + O2 = ? 6) H2S + O2 = ?

1) Ca + H2O = ?

The reaction between calcium (Ca) and water (H2O) can produce calcium hydroxide (Ca(OH)2) and hydrogen gas (H2). The balanced equation for this reaction is:

Ca + 2H2O -> Ca(OH)2 + H2 2) P + O2 = ?

The reaction between phosphorus (P) and oxygen (O2) can produce phosphorus pentoxide (P2O5). The balanced equation for this reaction is:

4P + 5O2 -> 2P2O5 3) CuO + H2 = ?

The reaction between copper(II) oxide (CuO) and hydrogen gas (H2) can produce copper (Cu) and water (H2O). The balanced equation for this reaction is:

CuO + H2 -> Cu + H2O 4) Zn + HCl = ?

The reaction between zinc (Zn) and hydrochloric acid (HCl) can produce zinc chloride (ZnCl2) and hydrogen gas (H2). The balanced equation for this reaction is:

Zn + 2HCl -> ZnCl2 + H2 5) H2 + O2 = ?

The reaction between hydrogen gas (H2) and oxygen gas (O2) can produce water (H2O). The balanced equation for this reaction is:
