What happens to a catalyst after a reaction?
In any reaction, a catalyst is never used up or changed. This means that at the end of every reaction you should always get your catalyst back. sometimes in the course of the reaction, the catalyst is used up, but by the end of the reaction it will always be reformed completely.
Catalyst are always enzyme it's true or false?
False . Catalysts can be many things ; enzymes and transition elements and their compounds , for example .So Enzymes are always catalysts but Catalysts are NOT always enzymes .
A catalyst for automobile exhausts removes carbon dioxide. True or False?
that is true
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
What type of elements include metals metalloids and nonmetals CATAlyst or representative or transition?
catalyst

Is this true or false Nonmetals are good conductors of heat and electricity?
True
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
A catalyst for automobile exhausts removes carbon dioxide. True or False?
that is true
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
Is catalyst a compound?
Not always, it can also be an element
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Which are more common metals or nonmetals?
Metal because there the biggest section of elements on the periodic table true statement.
Does nonmetals are highly reactive while metals are completely nonreactive?
It is not true; many metals are very reactive and several nonmetals are nonreactive.
What is ture of a catalyst?
It is true that a catalyst is used in chemical reactions to help speed up the reaction by reducing activation energy.
