What else can I help you with?
Why is the sublimation of dry ice and the expansion of gases not chemical reations?
A chemical reaction is one that changes the chemical properties of a substance. Sublimation is just going from solid to a gas and is only a change of state.
All of the chemical reations in an organism?
Metabolism
The total of all chemical reations in an organism?
metabolism
What is a protein that speeds up chemical reations in living systems?
an enzyme
Chemical digestion would not be possible without that speed up the rate of chemical reations in your body?
enzymes
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
What are the 4 different phases used in chemical reations?
solid, liquid, gas, and aqueous
What are the geological chemical reactions?
Dissolution, Mineral conversions, Exchange reations, Redox reactions.
What temperature does sprite freeze?
yes it does because the chemical reations are not uised to be freezing
What relationship exists between an enzyme?
they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells. they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells.
