Name a compound of hydrogen and oxygen showing stronger acidic behaviour than water?

0.16 gm hydrogen form 1.45 gm water on reaction with oxygen.Show that these results are in accordance with the law of reciprocal proportion.

In a mixture, two enantiomers are found to be present in 85% and 15% respectively. The enantiomeric excess (e,e) is

Two oxides of a metal, M were heated separately in hydrogen. The water obtained in each case were carefully collected and weighed. It was observed that- (1) 0.725g of the first oxide gives 0.18g of water and (2) 2.86g of the second oxide gives 0.36g of water. show that these results are in acccordance with the law of multiple proportions.
