Endothermic reactions need heat.
Chemical reactions in living organisms require a source of energy to start. This energy is typically obtained from molecules such as ATP. Additionally, enzymes play a critical role in catalyzing these reactions by lowering the activation energy required for the reaction to occur.
A common type of chemical reaction that doesn't involve heat is a precipitation reaction, where two soluble compounds in a solution react to form an insoluble solid called a precipitate. Other examples include acid-base reactions and redox reactions, which can occur without the need for external heat sources.
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.
no
No, not all chemical reactions require heat to start. Some reactions can occur at room temperature or even at low temperatures. Heat is often used to speed up reactions or provide enough energy to overcome the activation energy barrier.
yes they all need more or less start up energy

Heat is a form of energy. All chemical reactions need to have an energy of some sort. Fire is a chemical reaction. You can figure out the rest. na sooooooo!
Endothermic reactions need heat. Exothermic reactions give off heat.

Candle and all Chemical reactions

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.
