Carbon dioxide can be formed from the reaction of carbon monoxide and oxygen. How many moles of carbon monoxide must be reacted in order to produce 147 kJ of energy? 2 CO + O2 2 CO2 ΔH = -787 kJ

0.374 moles of carbon monoxide

Explanation:

Let's consider the following balanced thermochemical equation.

2 CO + O₂ ⇒ 2 CO₂    ΔH = -787 kJ

According to this balanced thermochemical equation, 787 kiloJoules of heat are released (this is the meaning of the minus sign) when 2 moles of carbon monoxide react. The moles of carbon monoxide that must react to produce 147 kJ of energy are:

(-147 kJ) × 2 mol CO/(-787 kJ) = 0.374 mol CO

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
