- 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 the same pressure and temperature): 1. volume gas X + 2 volumes gas Y2 volumes compound I 2. volumes gas X + 1 volume gas Y2 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.The vitamin niacin (nicotinic acid,C6H5NO2 ) can he isolated from a variety of natural sources, such as liver, yeast, milk, and whole grain.

Aldehydes have at least one hydrogen atom attached to the carbonyl carbon, which еТext means that C=0 must appear at the end of a carbon chain. Ketones do not have any hydrogen atoms attached to the carbonyl carbon because C=0 occurs between alkyl groups.
