Answer:
Energy is released in this reaction possibly in the form of heat thus it is an exergonic and or exothermic reaction.
The energy is sometimes transferred as heat, inflicting the reaction mixture and its surroundings to become hotter. The temperature increase may be detected employing a measuring device. Some samples of exothermic reactions are: Combustion .An chemical reaction may be a chemical process that releases energy by lightweight or heat.
Explanation:
It is an example of chemical weathering.
Because the carbon dioxide mixed with the air changes the chemical composition of limestone.

Answer: Fusion is a type of nuclear reaction.
Explanation:
Nuclear reaction is defined as those reaction in which nucleus of an atom is involved. There are two types of nuclear reaction:
- Fusion : In this type, two or more smaller atomic nuclei are combined together to form larger nucleus with release in energy
- Fission : In this type, one large unstable nucleus breaks down into two smaller nuclei with release in energy.
Answer:
2016 km
Explanation:
The escape velocity from Earth's surface is 
.
We need to find how many kilometers would a rocket travel in three minutes. It is a concept based on the definition of speed of an object.
Speed = distance per unit time
1 hour = 60 minutes
⇒ 3 minutes = 0.05 hour
1 m/s = 3.6 km/h
11200 m/s = 40320 km/h
So,
Hence, a rocket will travel 2016 km in 3 minutes.
