The chemical equation for the combustion of hydrogen is shown below. A scientist burns 6 g of H2 in excess oxygen
and collects 40 g of water. What is the percentage yield of
the reaction?
2H*2 + O*2 2H*2*0

I’m pretty sure it’s false i’m not sure

Decomposition is the cycle at which bacteria breaks down any organic material into the soil

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
