Chemical reactions involve the breaking and forming of chemical bonds, resulting in the rearrangement of atoms to form new substances. The total mass of the substances before a chemical reaction is equal to the total mass of the substances after the reaction, as dictated by the law of conservation of mass.

When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Is it true that lowering the temperature slows down most chemical reactions?
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
Do One enzymes can be used for many different types of chemical reactions is this true or false?
True. Some enzymes are able to catalyze multiple types of chemical reactions due to their flexible active sites that can accommodate different substrates. This versatility allows them to participate in various metabolic pathways within an organism.
Why do chemical reactions always involve a chemical change?
Chemical bonds always break in chemical reactions, causing changes in energy.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Why do reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
Chemical reactions that occur in cells are called biochemical reactions?
yes. true.
Do Chemical reactions involve the interplay of the electrons of the reacting chemical?
always.
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Do chemical reactions always involve changes in energy?
no
Is Electrons in an excited state are more likely to enter into chemical reactions true?
True
Chemical reactions that absorb energy will not occur without a source of energy true or false?
True. Chemical reactions that absorb energy, also known as endothermic reactions, require an external source of energy to proceed. Without this added energy, the reaction will not occur.
Electrolytes determine most of the chemical and physical reactions of the body?
True
What is true for all exergonic reaction?
One thing that is true for all exergonic reactions is that the reaction continues with a net release of what is called free energy. Exergonic reactions are chemical reactions.
Is this true about balanced chemical equations that they provide the molar ratios of reactants and products in chemical reactions?
Yes.
