the correct answer is combustion
when an organic compounds burns in the presence of oxygen the products are carbon dioxide and water. Combustion reactions yields a large amount of energy
an example for combustion reaction is as follows
combustion of methane;
CH₄ + 2O₂ --> CO₂ + 2H₂O
correct answer is
2. combustion
Since metals are malleable they are able to be bent and shaped.
Because gravity is trying to pull it down not up and when it's going down it's going with gravity not against it.
The balanced reaction formula is 2CuO + C = 2Cu + CO2. The change the 365 g to mole: 365/79.5=4.6 mol. So you can get 2.3 mol CO2. The mass is 2.3*44=101 g. So the answer is a.
it is water energy :) this is easy
