no
Endothermic reactions need heat.
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
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.
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.
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.
Candle and 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.
You need to be more specific with this question, forced chemical reactions? What happens to the patron? What happens to the drink?
Photosynthesis: The reaction where carbon dioxide and water are converted into glucose and oxygen by plants using sunlight. Endothermic reactions: Reactions that involve the absorption of heat energy from the surroundings, such as the decomposition of calcium carbonate to form calcium oxide and carbon dioxide.
