Hi vishal, you posted this in 2013 and its 2017 . I hope you have got your answer till now. If you haven't you can ask to me. Reply if you need.

To balance chemical equations, the number of atoms of each element in the reactants must be equal to the number of atoms of each element in the products. Let's balance the given chemical equations step by step:

1) Mg3N2 + N2 + H2O = Mg(OH)2 + NH3

To balance the equation, we can start by balancing the elements other than hydrogen (H) and oxygen (O) first, and then balance H and O last.

Start with balancing magnesium (Mg):

Mg3N2 + N2 + H2O = 3Mg(OH)2 + NH3

Next, balance nitrogen (N):

Mg3N2 + 3N2 + H2O = 3Mg(OH)2 + NH3

Now, balance hydrogen (H):

Mg3N2 + 3N2 + 3H2O = 3Mg(OH)2 + NH3

And, finally balance oxygen (O):

Mg3N2 + 3N2 + 3H2O = 3Mg(OH)2 + NH3

So, the balanced equation is:

Mg3N2 + 3N2 + 3H2O = 3Mg(OH)2 + NH3

2) KMnO4 + H2S + H2SO4 = KHSO4 + H2O + MnSO4

Start with balancing potassium (K):

KMnO4 + H2S + H2SO4 = KHSO4 + H2O + MnSO4

Next, balance the manganese (Mn):

KMnO4 + H2S + H2SO4 = KHSO4 + H2O + MnSO4

Now, balance the sulfur (S):

KMnO4 + H2S + H2SO4 = KHSO4 + H2O + MnSO4

Finally, balance the hydrogen (H) and oxygen (O):

2KMnO4 + 3H2S + 2H2SO4 = KHSO4 + 2H2O + MnSO4

So, the balanced equation is:

2KMnO4 + 3H2S + 2H2SO4 = KHSO4 + 2H2O + MnSO4

3) As2O3 + SnCl2 + HCl = SnCl4 + As + H2O

Start with balancing arsenic (As):

As2O3 + SnCl2 + HCl = SnCl4 + As + H2O

Next, balance the tin (Sn):

As2O3 + SnCl2 + HCl = SnCl4 + As + H2O

Now, balance the chlorine (Cl):

As2O3 + SnCl2 + 4HCl = SnCl4 + As + H2O

Finally, balance the hydrogen (H) and oxygen (O):

As2O3 + SnCl2 + 6HCl = SnCl4 + As + 3H2O

So, the balanced equation is:

As2O3 + SnCl2 + 6HCl = SnCl4 + As + 3H2O
