Question

Ammonia contains 82.35% of nitrogen and 17.65% of hydrogen. Water contains 88.90% of oxygen and 11.10% of hydrogen. Nitrogen trioxide contains 63.15% of oxygen and 36.85%of nitrogen. Show that these data instruct the law of reciprocal proportion.

Answer 1

Answer:

contains 82.35% of and 17.65% of

contains 88.90% of and 11.10% of

contains 63.15% of and 36.85% of

In ammonia, 17.65g of H combine with N = 82.35g

Therefore, 1g of H combine with N = 82.35/17.65 = 4.67g

In water, 11.10g of H combine with O = 88.90

1g of H combine with O = 88.90/11.10=8.01g

Ratio of the masses of N and O which combine well with fixed mass (is equal to 1g) of H =4.67: 8.01 = 1:1.72

In ratio of masses of N and O which combine with each other = 36.85: 63.15 = 1:1.72.

Thus, two ratios are the same. Hence, it proves the law of reciprocal proportions."
