<span>Combustion reaction is a chemical reaction where compounds and oxidants produce heat and new product during their reaction. The reaction between a HC (hydrocarbon) and O (oxygen) to produce CO2 (carbon dioxide) and H2O (water) is a standard form of a combustion reaction. Therefore,the correct answer would be A.
It is the combustion of gas (Methane, CH4) when it encounters oxygen (2O2). Methane will burn forming C02 gas and H20 gas.</span>
Photosynthesis is the process where plant calls take in Water, Carbon dioxide, and energy(sunlight) To produce oxygen and glucose(sugar)
Cellular respiration is the process where a cell takes in oxygen and glucose to produce water, carbon dioxide, and energy (ATP)
Photosynthesis only occurs in a plant cell, while cellular respiration occurs in all cells.
