Answer:
True
Explanation:
The majority of the reactions happened with a flow of heat. When there's no heat, the reaction is adiabatic.
For no adiabatic reactions, the heat can be released (evolution) by the system, so the reaction will be exothermic, or absorbed by the system (absorption), then the reaction is called endothermic.
<span>Carbohydrates because carbohydrate is a molecule that contains carbon, hydrogen and oxygen usually in a ratio of two hydrogen atoms for each carbon atom. Carbohydrates are also known as saccharides or carbs.They are basically sugar or starches.</span><span />
Answer:
3 mole O2
Explanation:
Need balanced equation first: O2 + 2SO2 --> 2SO3
assuming SO2 is in excess,
1.5 mol O2 (2moles SO3/1mole O2) = 3 mole O2
1.regulating ph
2.heating
3.adding some oppositely charged colloids
