The reaction of carbon dioxide(g) with hydrogen(g) to form carbon monoxide(g) and water(g) proceeds as follows: co2(g) + h2(g) > co(g) + h2o(g)when 16.4 grams of co2(g) react with sufficient h2(g) , 15.4 kj of energy areabsorbed .what is the value of > h for the chemical equation given? δhrxn = kj

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?
