Atomic Theory

Q. The elements X and Y combine in different ratios to form four different types of compounds XY, XY2, XY3, and XY4. Consider that there is enough of each compound to contain 2 g of X. in XY the mass of X is 2 g and the mass of Y is 4 g. Arrange the following ratios in order of their increasing value. Rank from highest to lowest ratio. To rank item as equivalent, overlap them.

Atomic Theory

Q. Two different compounds are obtained by combining nitrogen with oxygen. The first compound results fro combining 46.7 g of N with 53.3 g of O, and the second compound results from combining 17.9 g of N and 82.0 g of O. Calculate the ratio of the mass ratio of O to N in the second compound to the mass ratio of O to N in the first compound. Express your answer numerically.
