To predict the weight of oxygen required to combine with 1.00 g of nitrogen to form an oxide, we need to determine the ratio between the combining elements in each compound and then use that ratio to calculate the weight of oxygen.
Let's first look at the ratio of weights between hydrogen and nitrogen in ammonia. The given weight of nitrogen is 1.00 g, and the weight of hydrogen is 0.216 g. Therefore, the ratio of hydrogen to nitrogen in ammonia is 0.216 g : 1.00 g.
Next, we need to determine the ratio of weights between hydrogen and oxygen in water (H2O). The given weight of hydrogen is 0.126 g, and the weight of oxygen is not provided. We can assume that the weight of oxygen is x g. Therefore, the ratio of hydrogen to oxygen in water is 0.126 g : x g.
Now, let's find the ratio of nitrogen to oxygen in the desired oxide. Since we know the ratio of hydrogen to nitrogen and hydrogen to oxygen, we can set up a proportion:
Hydrogen to Nitrogen = Hydrogen to Oxygen
0.216g : 1.00g = 0.126g : x g
To solve the proportion, we can cross-multiply:
(0.216g)(x g) = (0.126g)(1.00g)
0.216x = 0.126
x = 0.126 / 0.216
x ≈ 0.583 g
Therefore, the weight of oxygen required to combine with 1.00 g of nitrogen to form an oxide is approximately 0.583 g.
