Answer:
H
Explanation:
If the energy content in the reactants is higher than the products, that means that the reaction must be giving away energy. So, in other words, chemical energy from the reactants must be released as heat.
occurs in fluids
Explanation:
Convection is a mode of heat transfer that occurs in fluids.
There are three types of heat transfer:
conduction convection and radiation
- Conduction is a mode of heat transfer that involves an actual contact between the molecules of the medium. It occurs mostly in solids
- Radiation uses electromagnetic waves to transfer heat between two bodies or places. It does not require a material medium. The heat of the sun reaches us by radiation.
- Convection is a mode of heat transfer in fluids. It involves the density differences between hot and cold liquids and gases.
- Water boils by convection currents.

Answer:
C
Explanation:
Since the solution have an observable color, that means that it absorbs light in the visible region hence it can be determined by colorimetry. Secondly, KMnO4 is a reducing agent which can be titrated against an oxidizing agent and it's concentration accurately determined.
