How do you write a balanced equation for the reaction of sodium hydroxide and hydrochloric acid?

How do you write a balanced equation for the reaction of sodium hydroxide and phosphoric acid?

Thanks for any help you can offer.

How do you write A balanced equation or The belanced equation?

If you meant the balanced eqn, the general rxn between an acid and a base is:
Acid + base ---> water + salt

For the first one:
NaOH +  HCl ---> H20 + NaCl

yes, I meant The balanced equation.  :)

so for the second question the answer is

NaOH + H3PO4---->H2O + NaCl

Are these balanced?

Where did phosphorus go?  NaCl is just one example of a salt.  Salts are just ionic compounds: eg. NaH2PO4.

3NaOH + H3PO4 → Na3PO4 + 3H2O.
