An aqueous solution containing 6.51 g naoh is added to an aqueous solution containing 19.3 g h3po4. (a) write a balanced equation for the acid-base reaction that should occur. (include physical states.)

Balanced chemical equation:

3NaOH)aq) + H₃PO₄(aq) → Na₃PO₄(aq) + 3H₂O(l)

Explanation:

Chemical equation:

NaOH)aq) + H₃PO₄(aq) → Na₃PO₄ + H₂O

Balanced chemical equation:

3NaOH)aq) + H₃PO₄(aq) → Na₃PO₄(aq) + 3H₂O(l)

How to balance:

NaOH)aq)     +   H₃PO₄(aq)     →       Na₃PO₄ + H₂O

Na = 1                                                Na = 3

O = 5                                                  O = 5

H = 4                                                   H = 2

P = 1                                                     P = 1

Next:

3NaOH)aq)     +   H₃PO₄(aq)     →       Na₃PO₄ + H₂O

Na = 1 × 3                                               Na = 3

O = 4 + 3=7                                             O = 5

H = 3 + 3 = 6                                            H = 2

P = 1                                                           P = 1

Next:

3NaOH)aq)     +   H₃PO₄(aq)     →       Na₃PO₄ + 3H₂O

Na = 1 × 3                                               Na = 3

O = 4 + 3=7                                             O = 4+ 3= 7

H = 3 + 3 = 6                                            H = 3 × 2 = 6

P = 1                                                           P = 1

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
