Answer 1

3K + P(красн.) = K3P(зел.)

 

Ba + 2H2O = Ba(OH)2 + H2

 

Mg + H2SO4 = MgSO4 + H2

Answer 2

Electron Balancing

To balance the given chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. We'll go through each equation one by one.

a) K + P = ?

The given chemical equation is not balanced. To balance it, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Balanced Equation: 2K + P4 = 2KP

b) Ba + H2O = ?

The given chemical equation is not balanced. To balance it, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Balanced Equation: Ba + 2H2O = Ba(OH)2 + H2

c) Mg + H2SO4(konc) = ?

The given chemical equation is not balanced. To balance it, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Balanced Equation: Mg + H2SO4(konc) = MgSO4 + H2

d) Zn + N2 = ?

The given chemical equation is not balanced. To balance it, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Balanced Equation: 3Zn + N2 = Zn3N2

e) Ca + HNO3(konc) = ?

The given chemical equation is not balanced. To balance it, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Balanced Equation: Ca + 2HNO3(konc) = Ca(NO3)2 + H2
