1 some reaction can be very fast and consume the products of other reactions as they form, for example multistage reactions like blood clotting.
2 some reactions are highly reversible such as the oscillating clock reactions

Why are reactants important in chemistry?
A chemical reaction without reactants is not possible.
How does changing the amounts of reactants in a chemical reaction change the chemical compositions of the products?
Yes, it is possible; for example complete or not complete burning.
Define products in a chemical reaction?
They are substances formed by a chemical reaction. All atoms that are present in the reactants are present in the product. Products are always on the RIGHT of the formula.Exothermic reaction:Ex: Reactants--->Products + EnergyEndothermic reaction:Ex: Reactants+energy--> Products...Reactants...............Products{6CO2+6H2O}--->{C2H12O6+6O2 }
Two colorless solutions were mixed. a yellow precipitate was formed.what possible reactants were mixed and what was the yellow coloured precipitate formed due to?
chemical change
Why do reaction rates slow as time goes on?
There are fewer reactants left to collide.
Why are reactants important in chemistry?
A chemical reaction without reactants is not possible.
Is a solid formed from a liquid reactants during a chemical reaction?
Yes, it is possible.
How does changing the amounts of reactants in a chemical reaction change the chemical compositions of the products?
Yes, it is possible; for example complete or not complete burning.
The only sure evidence for a chemical reaction is?
A kind of chemical bond in the possible reaction products that did not exist in the reactants, or a kind of chemical bond in the reactants that does not exist in the possible reaction products.
Why is an equilibrium price important?
It is how sellers determine the best possible price for their products for optimal profit.
Can you determine the number of moles of any substance produced in a reaction if you know the number of moles of at least two of the reactants?
Yes, it is possible.
What effect does a promoter catalyst have on the position of the equilibrium?
By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
Is it possible to tell whether a chemical change has occurred by watching atoms form new substances?
if the atoms form substances that are chemically different from the reactants, then a "chemical" change has occurred.
Define products in a chemical reaction?
They are substances formed by a chemical reaction. All atoms that are present in the reactants are present in the product. Products are always on the RIGHT of the formula.Exothermic reaction:Ex: Reactants--->Products + EnergyEndothermic reaction:Ex: Reactants+energy--> Products...Reactants...............Products{6CO2+6H2O}--->{C2H12O6+6O2 }
What is a reactant in a chemical equation example?
Almost any chemical element or compound can participate in some type of chemical reaction and thereby be a reactant. One of the more common reactants is oxygen. It may be that only helium can never be a reactant.
Two colorless solutions were mixed. a yellow precipitate was formed.what possible reactants were mixed and what was the yellow coloured precipitate formed due to?
chemical change
Hydrogen peroxide breaks down into water and oxygenexplain why this is a chemical reactionwhat are the reactants and products in the reaction?
The chemical reaction is caused because it is not possible to rearrange water and oxygen to form hydrogen peroxide. This is taught in science.
