Answer 2

You have to match up the positive and negative charges and swap them between the compounds. This would leave you with NaCl and H2O.

Answer 3

NaOH & HCl are the reactants & NaCl & H2O are the products.

Answer 4

NaOH is a alkali (bases soluble in water) & HCl is an acid.

1) Acid + base → Salt + water + heat (neutralisation reaction).

2)The equation is already balanced.

To check whether it is balanced check whether the number of atoms of each kind are equal on both RHS & LHS.

Now you must be wondering about H2 on the R.H.S & H on the L.H.S. You might think it is not balanced. But i
t is balanced because there are t H(s) on L.H.S one from HCl & the other from NaO"H".

3)NaOH & HCl are the reactants & NaCl & H2O are the products.
