Two experiments were conducted: 1.2.750 g of copper(II) oxide, CuO₂, was reduced by heating at high pressure with excess hydrogen to yield 2.196 g of copper Cu. 2.1.179 g of copper Cu was dissolved in nitric acid to yield copper(II) nitrate, which was converted to 1.476 g copper(II) oxide, CuO₂, on ignition. Show that the results illustrate the law of definite proportions by calculating the percentage of oxygen in copper(II) oxide in experiments 1 and 2. Express your answers numerically to two decimal places, separated by commas. Do not enter the percent symbol. View Quailable

A 5.93 g sample of calcium sulfide was decomposed into its constituent elements, producing 3.30 g of calcium and 2.63 g of sulfur. Which of the statements are consistent with the law of constant composition (definite proportions)? Every sample of calcium sulfide will have 3.30 g of calcium. The ratio of calcium to sulfur will vary based on how the sample was prepared. The mass percentage of calcium plus the mass percentage of sulfur in every sample of calcium sulfide equals 100%. The mass ratio of S to Ca in every sample of calcium sulfide is 0.80. Every sample of calcium sulfide will have 55.6% mass of calcium.

A 8.63 g sample of calcium sulfide was decomposed into its constituent elements, producing 4.80 g of calcium and 3.83 g of sulfur. Which of the statements are consistent with the law of constant composition (definite proportions)? The mass percentage of calcium plus the mass percentage of sulfur in every sample of calcium sulfide equals 100%. The mass ratio of Ca to S in every sample of calcium sulfide is 1.25. Every sample of calcium sulfide will be 55.6% by mass calcium. The mass ratio of S to Ca will vary based on how the sample was prepared. A different 8.63 g sample of calcium sulfide will contain a different amount of calcium.
