How are atoms and molecules affected by chemical reactions?
In a chemical reaction, atoms are rearranged and bonds between them are broken and formed to create new substances. Molecules can be broken down into smaller molecules or combined to form larger molecules through chemical reactions. Overall, chemical reactions alter the arrangement of atoms and molecules to create different substances with unique properties.
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
Chemical reactions that create energy within a cell are referred to as?
6co2
Does exothermic create more energy?
No, it releases energy to it's surroundings!
What is the diffrencence between exothermic reaction and chemical reaction?
A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.
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.
Do reactions create energy?
Reactions do not create energy; rather, they involve the conversion of energy from one form to another. In some reactions, energy is released (exothermic reactions), while in others, energy is absorbed (endothermic reactions). Energy is always conserved in a chemical reaction according to the law of conservation of energy.

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
Does chemical reactions create molecules and compounds?
Yes, chemical reactions can create new molecules and compounds by rearranging atoms in existing substances. This process involves breaking and forming chemical bonds to create different combinations of elements.
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.
