What are enzymes considered?
Enzymes are considered to be catalysts; they increase the rate of a chemical reaction.
Is the reactivity of copper with oxygen considered a chemical or physical property?
The correct spelling is "reaction of copper with...' 1. Chemical reactivity is a chemical property. 2. A chemical reaction involve a chemical change.
When paint dries is it considered an exothermic reaction?
No, the drying of paint is considered a physical change, not a chemical reaction. The drying involves the evaporation of the solvent in the paint, and it is not an exothermic reaction because it does not involve the release of heat.
What must a occur for a change to be a chemical reaction?
The answer choices weren't provided. There must be a change in chemical properties for a change to be considered a chemical reaction.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Is sawing a log chemical reaction?
No, that would probably be considered a physical change. It is only a chemical reaction its chemical makeup is changed.

What kind of chemical reaction would the production of water be considered?
product
Would baking soda and vinegar be considered a chemical reaction?
Yes.
Why is photosynthesis considered a chemical reaction?
Photosynthesis is considered a chemical reaction because it involves the conversion of light energy into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells and involves the chemical reactions of carbon dioxide and water to produce glucose and oxygen.
What must a occur for a change to be a chemical reaction?
The answer choices weren't provided. There must be a change in chemical properties for a change to be considered a chemical reaction.
Is water considered a base in chemical reactions?
Water is not considered a base in chemical reactions. It can act as both an acid and a base depending on the specific reaction.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Would a reaction with oxygen be a chemical or physical property?
A reaction with oxygen would generally be considered a chemical property because it involves a change in the chemical composition of the substances involved. Physical properties, on the other hand, do not involve changes in chemical composition.
