Suppose you had 1 mole of oxygen (o2). how many moles of hydrogen (h2) would react completely with the oxygen, and how many moles of h2o would b produced? show the balance equation with explanations.

First, we write an equation for the reaction of Hydrogen and Oxygen to produce water:
H₂ + O₂ ⇒ H₂O
This equation is not balanced, we then balance the Oxygens:
H₂ + O₂ ⇒ 2H₂O
And now the Hydrogens:
2H₂ + O₂ ⇒ 2H₂O
Therefore, if one mole of Oxygen reacts, it will require two moles of Hydrogen and produce two moles of water.

Answerstudying coal cumbustion as an energy source;

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !
