Which environmental changes can cause an increase in the rates of reactions in cells?
increased temperature
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
What 4 things can increase the rate of a chemical reaction?
Concentrations of reactants; concentrations of products; changes in temperature (usually higher temperatures favor faster reactions); catalyst; for some reactions, incident light; and, for reactions with a volume change, changes in pressure.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Can you increase the number of particles of a substance in a chemical reaction?
In some electrochemical reactions the no. of particles automatically changes because of association and dissociation in solution
Which environmental changes can cause an increase in the rates of reactions in cells?
increased temperature
How does temperature aff ect the rate of chemical changes?
An increase in temperature increases the rate of most, but not all, chemical reactions.

What are names for chemical changes?
This name is chemical reactions.

do oreos undertake any chemical changes?
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
Why do chemical reactions always involve a chemical change?
Chemical bonds always break in chemical reactions, causing changes in energy.
What reaction is in antacids chemical or physical?
Chemical reactions are of course chemical changes.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.

Why do chemical reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
Are chemical reactions accompanied by chemical changes in energy?
Yes. Refer to endothermic and exothermic reactions to learn more.
