Endothermic reactions need heat.
Not all chemical reactions require water. While many reactions may occur in the presence of water, there are also reactions that take place in other solvents or under dry conditions. The presence of water can often act as a catalyst or a medium for facilitating certain reactions, but it is not a universal requirement for all chemical reactions.
These are not chemical reactions but thermonuclear reactions.
The question is quite vague, as there are many chemical reactions and none are specified, so the two chemical reactions must be specified before an answer can be given.
All atoms involved in a chemical reaction have an atomic nucleus.
Chemical reactions are a topic in chemistry, gravity is a topic in physics, and atoms are a topic in both chemistry and physics.
Chemical weathering means that rocks are worn down by chemical reactions. This is unrelated to gravity.
Chemical weathering is the breakdown of rocks through chemical reactions. Gravity can contribute to chemical weathering by exerting pressure on rock formations, causing them to crack and fracture. This can expose a larger surface area of the rock to chemical agents like water and oxygen, accelerating the process of chemical weathering.

You need to be more specific with this question, forced chemical reactions? What happens to the patron? What happens to the drink?
Chemical reactions occur in respiration, photosynthesis, and more life processes. Respiration and photosynthesis are both essential for life to exist.
