- In a combustion reaction, the most common fuel that burns contains compounds called hydrocarbons. This organic compound reacts quickly with oxygen and produces carbon dioxide (CO2) and water vapor (H2O). The reaction typically gives off heat and light as well. The combustion of methane is represented by the equation: CH4 + 2O2 → CO2 + 2H2O 1. In the above reaction what compound is oxidized? 2. Give another example of a hydrocarbon combustion reaction and write the equation.arrow_forwardIn the combustion of butanol (CH 00), what mass (in g) of butanol must react to produce 55.4 g of product?

- pour it 2. Still sleepy from a late night studying, you take the milk out of the refrigerator and pour it on your lemon juice to milk to make paneer (fresh cheese). As a group, craft a chemical explanation for the fact of coagulated milk onto your cereal. The last time you saw milk coagulate like that was when you added breakfast cereal. Unfortunately, by the time you notice the funny smell you have already poured clumps lemon juice to milk to make paneer (fresh cheese).
