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
