Combustion analysis of 1.0 g of a compound containing only carbon, hydrogen and oxygen gives 2.3 g of carbon dioxide and 0.93 g of water. If the relative molecular mass of the compound is 58, calculate the empirical and molecular formula of the compound.

What mass of water would be required in grams to make a 15% (m/m) KCl solution with 3.8 g of KCl?

Which one is more reactive?

A- Methyl iodide

B- Ethyl iodide

C- Propyl iodide

D- Isopropyl iodide

Please address the query as soon as possible.

Thank You!
