the number of particles stays the same because you have not made or destroyed anything

Why does increasing concentration usually increase reaction rate?
Lncreasing the number of particles in a given volume, means they are more concentrated. Since there are more particles in a given volume it means that they will collide more often with the reacting particles. 'More often' means an increasing rate of reaction.
According to collision theory increasing the concentration of the reactants in a chemical reaction increases?
A.the rate of collisions between two particles.
As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.
How many potassium atoms are in the reactants of the chemical reaction?
The same number you started with. In every chemical reaction the total number of atoms at the start is the same as the number of atoms at the end.
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
These particles are protons and neutrons; but to be correct the mass of electrons must be added.
Is a change in the number of particles in a suspension a chemical reaction?
This is not a chemical reaction.
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
Does adding a catalyst increase the number of particles of a substance available to react in a chemical reaction?
No, the catalyst doesn't increase the number of reactant particles.
Why do we need to know the number of particles in a chemical reaction?
so we can see if anything has changes :)
Can you increase the number of particles of a substance in a chemical reaction?
In some electrochemical reactions the no. of particles automatically changes because of association and dissociation in solution
According to kinetic and collision theory why does increasing the temperature of the reaction increase the rate of reaction?
The likelihood that two particles will collide in a given time increases. The number of particles per volume increases.
What happens to the number of molecules of the gas when it is compressed?
It does not change, unless a chemical reaction in the gas happens.
Why are there the same number of particles before and after the reaction?
There are the same amount of particles at the end of a reaction as in the beginning of that reaction because of the law of conservation of mass. You simply cannot have particles disappearing to nowhere.
What does not increase the number of particles of a substance available to react in a chemical reaction?
increasing the surface area
What happens to the total number of atoms of each element before and a after a chemical reaction?
It does not change
When an atom undergoes oxidation what happens to the number of neutrons?
Oxidation is a chemial reaction; the atom and the number of neutrons remains unchanged.
What happens to the atomic number of an element if it emits 1 alpha particle and 1 beta particles?
It drops 2
