What else can I help you with?
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.
Is it true that at equilibrium, no chemical reactions take place?
At equilibrium, the rates of the forward and reverse reactions are equal, but chemical reactions are still occurring.
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 it true that all chemical reactions are reversible?
No, not all chemical reactions are reversible. Some reactions are irreversible, meaning they cannot easily be reversed to reform the original reactants.
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?
This is true. Energy is required to begin all reactions.
Electrolytes determine most of the chemical and physical reactions of the body?
True
