Many elements have this property, including all the alkali metals and the heavier alkaline earth metals. Also, many compounds such as sulfuric acid have exothermic heats of solution, but solution is not technically a "reaction."

What is the difference between endothermic and exothermic And give examples?
Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. Example: Mixture of sodium and chlorine to yield table salt In other words, combination reactions are exothermic. Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. For example: In the process of photosynthesis, plants use the energy from the sun to convert carbon dioxide and water to glucose and oxygen.
Physical and chemical changes can be either exothermic or endothermic changes?
The two terms are probably used most often to describe chemical reactions - whether or not they absorb or require heat (endothermic) or create release heat (exothermic). However, since the terms simply mean "absorbing heat", and "giving off heat", they can be used to describe any such event, physical, chemical or nulear. Ray
Dose a chemical reaction create molecules and compounds?
Yes, it is true: all chemical reactions create new molecules of compounds.
Chemical reactions that create energy within a cell are referred to as?
6co2
When paint dries is it considered an exothermic reaction?
Yes, completely because there is no other chemical added to the paint to create a chemical reaction or to act as a internal catalyst.
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 chemical conducts heat?
there are alot of chemical mixtures that create exothermic REACTIONS, but no chemical in particular. my favorite chemical reaction is thermite. (alluminum powder, iron(ii) oxide) temperatures reach 9000 degrees!
How enzymes control chemical reactions?
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
What have chemical reactions help us create?
Salt

Yes, it is true.
What is the similarity between combustion and decomposition?
•They both need oxygen to happen. •They both create energy, water and carbon dioxide. •Both processes give off heat •They are both considered chemical reactions.

What is the fizz when the baking soda and vinegar are combined?
When vinegar and baking soda are mixed, the chemical reactions that take place create carbon dioxide, which rises to the surface very quickly in bubbles, causing the fizz.
Is it true or false that Chemical reactions rearrange atoms but do not create or destroy them?
true
