Question

Розтавте коефіцієнти в рівняннях реакціі 1) F2+H2O> HF+O2 2) CuOH>Cu2O+H2O 3)C2H2+O2>CO2+H2O 4)FeS2+O2>Fe2O3+SO

Answer 1

2F2+2H2O=4HF+O2
4CuOH=2Cu2O+2H2O
2C2H2+5O2=4CO2+2H2O
4FeS2+11O2=2Fe2O3+8SO2

Answer 2

Balancing Chemical Equations:

1) F2 + H2O -> HF + O2 To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

F2 + 2H2O -> 4HF + O2 [[1]]

2) CuOH -> Cu2O + H2O To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

2CuOH -> Cu2O + H2O [[2]]

3) C2H2 + O2 -> CO2 + H2O To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

C2H2 + 5/2O2 -> 2CO2 + H2O [[3]]

4) FeS2 + O2 -> Fe2O3 + SO To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

4FeS2 + 11O2 -> 2Fe2O3 + 8SO2 [[4]]

Please note that the coefficients in balanced chemical equations represent the relative number of molecules or moles of each substance involved in the reaction.
