What chemical reactions can give off heat or what?
These chemical reactions are named exothermic.
What chemicals reactions give out heat?
Some examples of chemical reactions that give out heat are combustion reactions (e.g. burning of wood), oxidation reactions (e.g. rusting of iron), and neutralization reactions (e.g. mixing an acid and a base). These reactions release energy in the form of heat due to the rearrangement of atoms and the breaking and forming of chemical bonds.
Do chemical reactions give out energy in the form of heat light or sound?
Yes, chemical reactions can give out energy in the form of heat, light, or sound. This energy is released due to the breaking and forming of chemical bonds during the reaction.
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.

Yes, chemical reactions can give out energy in the form of heat, light, or sound. This energy is released due to the breaking and forming of chemical bonds during the reaction.
Can energy be asorbed or released during chemical reactions?
Yes they can be either absorbed or release during chemical reactions. That is why some reactions explode or give off heat and some absorb heat making them cooler.
Do most of the chemical reactions that give off light also produce heat?
Yes, most chemical reactions that give off light also produce heat. This phenomenon is known as chemiluminescence, where the energy released during the reaction is emitted as both light and heat. However, not all reactions that produce light necessarily produce heat, as some reactions can be endothermic and absorb heat instead.
Are chemical reaction affected by differences in temperature?
Yes, temperature has an effect on the speed of the reaction. Also most chemical reactions create heat. I feel that it is not exactly correct to say that most chemical reaction create heat. That is true for exothermic reactions, which give off heat, but endothermic reactions absorb heat instead.
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
Do all chemical reactions need heat to start them off?
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.
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Chemical reaction that produces heat?
Chemical reactions that produce heat (or energy) are known as Exothermic Reactions. (Example: combustion of fuels)
Does energy conversions always give off heat?
No, not all energy conversions give off heat. Some energy conversions, such as nuclear reactions and chemical reactions, can produce other forms of energy like light or sound instead of heat.
What is the study of heat transfer during chemical reactions and changes of state is?
The study of heat transfer during chemical reactions and changes of state is known as thermochemistry. Thermochemistry deals with the heat of reaction, enthalpy, and heat transfer in chemical processes. It is important in understanding the energy changes associated with chemical reactions.
