How many moles of O2will be produced from 6.2 moles of water?​

I hope This will help youand please mark me as Brilliant

Explanation:

The formula, H2O tels us that there are the same number of moles of Oxygen as there are of water. The (understood )molecular coefficient of H2O is 1. The (understood ) coefficient of O in the formula is also 1. The number of moles of oxygen is the same as the number of moles of water. This is moles of oxygen atoms. If the question wants moles of oxygen gas, O2, then it will be half as many I think that is what they want, so I would answer 3.1 moles of O2.

- decrease the number of plants and animals living in the water.
