Question

Продолжить уравнения реакции 1) al+ HCl= 2) CuO + HNO3= 3) NaOH+FeCl3= 4)Cu+HCl=

Answer 1

1 Al+2HCl=alcl2+ h2
2 cuo+2hno3=cu(no3)2+h2o
3 3naoh+fecl3=3nacl+fe(oh)3
4 cu+2hcl=cucl2+h2

Answer 2

1. 2Al + 6HCl → 2AlCl3 + 3H2

2. CuO + 2HNO3 → Cu(NO3)2 + H2O

3. 3NaOH + FeCl3 → 3NaCl + Fe(OH)3

4. Cu + 2HCl → CuCl2 + H2
