Me with the correct answer how many moles of h2o are needed to produce 1 mole of o2 in the following equation? 2h2o > 2h2 + 1o2 a. 3 b. 4 c. 1 d. 2

The coefficients shown in the balanced equation is showing us the reaction needs 2 moles of H2O to produce 2 moles of H2 and one mole of O2.
This means the answer is D.2

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
