Question

Расставьте коэффициенты следующих схемах реакций Al+O2=Al2+O3 N2+H2=NH3 Ca+H3PO4=Ca3(PO4)2+H2 Ba(OH)2+HCl=BaCl2+H2O ZnCl2+AgNo3=AgCl+Zn(NO3)2 Все цифры маленькие по размеру

Answer 1

4Al+3O2=2Al2O3
N2+3H2=2NH3
3Ca+2H3PO4=Ca3(PO4)2+3H2
Ba(OH)2+2HCl=BaCl2+2H2O
ZnCl2 + 2AgNO3 = Zn(NO3)2 + 2AgCl

Answer 2

Coefficients for the Given Reactions:

1. Al + O2 = Al2O3 - The coefficients for this reaction are: 4 Al + 3 O2 = 2 Al2O3.

2. N2 + H2 = NH3 - The coefficients for this reaction are: N2 + 3 H2 = 2 NH3.

3. Ca + H3PO4 = Ca3(PO4)2 + H2 - The coefficients for this reaction are: 3 Ca + 2 H3PO4 = Ca3(PO4)2 + 3 H2.

4. Ba(OH)2 + HCl = BaCl2 + H2O - The coefficients for this reaction are: Ba(OH)2 + 2 HCl = BaCl2 + 2 H2O.

5. ZnCl2 + AgNO3 = AgCl + Zn(NO3)2 - The coefficients for this reaction are: 2 ZnCl2 + 2 AgNO3 = 2 AgCl + Zn(NO3)2.

Please note that the coefficients provided above are based on the given reactions and may vary depending on the specific conditions and reaction conditions.
