Yes, every chemical reaction requires activation energy, though in some cases the ambient heat of room temperature is enough to provide that energy.
Yes, they do.
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
No, a chemical reaction that absorbs energy is called an endothermic reaction. The transfer of heat from the surrounds into the substance. In reactions, energy is always CONVERTED, not created which means that nothing can be converted i.e. heat to chemical if there is no heat or initial energy.
An enzyme is not required in a chemical reaction. While reactants, energy, and a chemical reaction pathway are essential components of a chemical reaction, enzymes can speed up the reaction but are not always necessary for it to occur.
One example of a chemical reaction that releases energy is the combustion of methane gas (CH4) in the presence of oxygen. This reaction produces carbon dioxide (CO2) and water (H2O) along with a significant amount of heat and light energy.
Yes, they do.

An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.

Energy. Different chemical reactions require different amounts of energy to occur, which can affect the speed and extent of the reaction.
Endothermic reactions are chemical reactions that absorb free energy, typically in the form of heat. These reactions require an input of energy to proceed. Examples include photosynthesis and the melting of ice.
No. They include their energy source, to glow for a while (thanks to a chemical reaction).
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
