Given the following equation: 2h2o --> 2h2 +o2 what mass of oxygen would form from 2.30 moles of water? question options: 25.1 36.8 25.1 39.3

36.8 g of oxygen would form from 2.30 moles of water

Explanation:

According to given balanced equation, 2 moles of water forms 1 mole of oxygen

So moles of oxygen would form from 2.30 moles of water=

Molar mass of is 32 g/mol

So mass of would form=

hence 36.8 g of oxygen would form from 2.30 moles of water

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

if you mean hydrogen and oxygen then water is the product
