Question

РАССТАВЬТЕ КОЭФФИЦИЕНТЫ В СЛЕДУЩИХ СХЕМАХ РЕАКЦИЙ

Answer 1

1.2NaH+ 2H2O = 2NaOH + 2H2

2.2K+2H2O= 2KOH +H2

3.2Na + 2HBr = 2NaBr + H2

4. Mg + 2HI= MgI2+H2

5.4Si + 4NaOH+ 4H2O = 4Na2SiO3+ 6H2O

6.2Al + 3H2SO4 = Al2(SO4)3 + 3H2

7.2NaCl + 2H2O = 2NaOH +H2 + Cl2

8.BaH2 + 2HCl= BaCl2 +2H2

9.Fe + 2HBr = FeBr2 + H2

10.Ca + 2H2O = Ca(OH)2 + H2
