Look at the balanced equation below: C2H6O + 3 O2 → 2 CO2 + 3 H2O

If you produced 11.5 moles of H2O, how many moles of O2 were used?

11.5 moles O2
11.5 moles O, 2

34.5 moles O2
34.5 moles O, 2

3.83 moles O2
3.83 moles O, 2

7.67 moles O2

11.5moles of oxygen gas

Explanation:

The reaction equation is shown below;

     C₂H₆O  + 3O₂ → 2CO₂  +  3H₂O

 We were given  11.5moles of H₂O produced;

Since the equation is balanced;

          3 mole of oxygen gas was used to produce 3 mole of water

        11.5 moles of water will be produced   = 11.5moles of oxygen gas

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

a. hope i'm right
