10. CHALLENGE. You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react "gas X" with "gas Y" to make the products, you get the following data (all at standard pressure and temperature): 1 volume "gas X" + 2 volumes "gas Y" → 2 volumes compound I 2 volumes "gas X" + 1 volume "gas Y" → 2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y and suggest identities.

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Question
Transcribed Image Text:10. CHALLENGE. You have two distinct gaseous compounds made from element X and element Y.
The mass percents are as follows:
Compound I: 30.43% X, 69.57% Y
Compound II: 63.64% X, 36.36% Y
In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic?
Triatomic? That is for you to determine.) When you react "gas X" with "gas Y" to make the
products, you get the following data (all at standard pressure and temperature):
1 volume "gas X" + 2 volumes "gas Y" → 2 volumes compound I
2 volumes "gas X" + 1 volume "gas Y" → 2 volumes compound II
Assume the simplest possible formulas for reactants and products in the chemical equations
above. Then, determine the relative atomic masses of element X and element Y and suggest
identities.
