1 minute equals 60 kph.........Thanks Tionne17 for asking!!!
Combustion is a type of exothermic chemical reaction that generates light and heat in most cases, and occurs fairly quickly.
<h3>What is an exothermic reaction?</h3>
An exothermic reaction is one that when it occurs releases energy in the form of heat or light to the environment.
<h3>Characteristics of an exothermic reaction</h3>
- When this type of reaction occurs, the products obtained have lower energy than the initial reactants.
- Most of the exothermic reactions are oxidation, and when they are very violent they can generate fire, as in combustion.
- Combustion is a very fast oxidation reaction that occurs between materials called fuels and oxygen.
Therefore, we can conclude that combustion is an example of an exothermic reaction that releases large amounts of heat, which can lead to fire.

Answer:
Hydrogen gas is evolved at the cathode and chlorine gas at the anode.
Explanation:
The solution will ionise. Hydrogen ions, H+, will migrate to the negative cathode ( where the current leaves the solution and chloride ions Cl- will migrate the the positive anode.
Answer:
homologous structures.
Explanation:
If you look at many different organisms, you will see similar structures. Like humans have a forearm, birds have a wing, whales have fins, leopards have legs. The bones evolvolved to fit the animal
