All atoms involved in a chemical reaction have an atomic nucleus.
Not by chemical means. A nuclear reaction can be induced by bombarding the nucleus with neutrons, alpha particles, beta particles, gamma rays, high velocity nuclei from a particle accelerator, or cosmic ray particles. Neutrons are most effective at causing nuclear reactions as they have no charge and are reasonably massive.
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.
No, chemical reactions do not require gravity to occur. Chemical reactions involve the rearrangement of atoms and molecules, which can happen in the absence of gravity. Gravity may influence the rate or behavior of certain reactions on Earth, but it is not necessary for the reactions themselves.
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.

Endothermic reactions need heat.
In fusion reactions, nuclei need to overcome the strong electromagnetic repulsion to merge and release energy, requiring high temperatures to achieve the necessary kinetic energy. In fission reactions, nuclei need to be bombarded by neutrons to induce a split, a process that can occur at lower temperatures.

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.

Candle and all Chemical reactions
All chemical reactions need a certain amount of activation energy to get started.
