Answer:
Equation 1 - nuclear fission
Equation 2 - nuclear fusion
Explanation:
Nuclear fission is a reaction in which a large nucleus is split into smaller nuclei when it is bombarded by neutrons. The process produces more neutrons to continue the chain reaction. This is clearly depicted in equation 1 as shown in the question.
Nuclear fusion is a reaction in which two light nuclei combine in order to form a larger nuclei. This is clearly depicted in equation 2 as shown in the question.

Answer:
Filling in the blank, this is an example of <u>chemical weathering</u> which happens <u>to rocks</u> overtime.
Explanation:
Chemical weathering occurs when rocks are disintegrated by chemicals.
Rain water becomes acid rain when it reacts with carbon dioxide in the atmosphere (to form carbonic acid, HCO3).
When acidic rainwater falls and stays on rocks, chemical reactions take place with the minerals present in the rock, causing the rock to weather.
Areas with immense carbon dioxide and sulphur dioxide pollution increases rain water acidity, which in turn causes moisture in the atmosphere to dissolve these gases and produce acid rain.
