Question

Given the following equation:
2 H2 + O2 → 2 H2O
How many kg of H2O would be produced from 300.0 kilograms of hydrogen gas? NOTE: All numbers located immediately after elemental symbols should be considered subscripts.

Answer 1

Answer:

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

This component is called the solvent and may be viewed as the medium in which the other components are dispersed, or dissolved

Answer 2

By the looking at the stochiometric values of the equation

2 g H2 + 32 g O ==> 36 g water

therefore 1 g of H2 will produce 18g H20 hence 300 kg == 5400 kg h20

but there must be an excess of O2
