Why is an enzyme unchanged in a chemical reaction?
Enzymes are very efficient catalysts for biochemical reactions. They do not undergo permanent changes and so remain unchanged at the end of the reaction.
What properties of the water won't change?
The chemical formula remain unchanged.
Why the catalyst remain unchanged after the reaction?
A catalyst remains unchanged after a reaction because it facilitates the reaction by lowering the activation energy required for the reaction to occur without being consumed in the process. It participates in the reaction by temporarily forming intermediate complexes but is regenerated at the end of the reaction. This allows the catalyst to be used repeatedly in multiple reaction cycles. Thus, its chemical identity and quantity remain the same before and after the reaction.
Did the properties of the substances change after mixing?
After the mixing the properties of substances remain unchanged.
Is dissolution of resin in alcohol a chemical change or a physical change?
Dissolution is a physical change because the molecule remain unchanged.
Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
Is mealting a chemical reaction?
No, melting is a physical change of state, the chemical properties and formula of the substance remain unchanged.
Is it true that the amount of matter present appears to change during a chemical reaction?
The total mass remain unchanged.
Do enzymes get used up in a reaction, or do they remain unchanged and available to catalyze multiple reactions?
Enzymes remain unchanged and available to catalyze multiple reactions. They are not used up in a reaction.
Why is an enzyme unchanged in a chemical reaction?
Enzymes are very efficient catalysts for biochemical reactions. They do not undergo permanent changes and so remain unchanged at the end of the reaction.
How can someone tell when equillibrium in a reaction has occured?
Equillibrium in a reaction has occured when the concentration of compounds remain unchanged.
What will happen if there is no physical and chemical change?
The system remain unchanged.
What properties of the water won't change?
The chemical formula remain unchanged.
How does the state of matter change crayons?
The state of matter remain unchanged.
Why is a lava lamp not a chemical change?
The chemical structures remain unchanged.
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
