In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.

What happens to the reactants in a chemical reaction?
Put casually, they react with each other to form products. e.g. Reactants A & B form products C & D A + B = C + D
What causes pressure changes of reactants to affect the reaction rate?
The frequency of collisions is changed.
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.
What is a reactant?
A reactant is a substance that participates in and changes during a reaction.
What is meant by the term reactants in terms of chemical changes?
Nature of reactants refers to chemical identities of the reactants.
In a reaction the numbers of some of the elements changes from the reactants to the products?
oxidation
In what kind of reaction can the products form the reactants?
The type reaction that changes the reactants into products is called a chemical reaction. Most chemical reactions can run forward or backward.
What is involved in a chemical reaction?
Chemical ReactionA chemical reaction is composed of REACTANTS and PRODUCTS. The starting compounds and/or elements in the reaction are known as reactants. Once they are combined, the resulting elements/compounds are called the products. Basically:Reactant ---> ProductOr:Reactant 1 + Reactant 2 ---> Product 1 + Product 2Example:Magnesium Chloride + Lithium Floride ----> Lithium Choride + Magnesium FluorideMgCl2 + LiF = LiCl + MgF2
What are the two basic parts of a chemical reaction?
Chemical reaction is the making and breaking of chemical bonds, leading to changes in the composition of matter. Chemical reactions do not create or destroy matter; they only rearrange it in various ways.
Why must the states of all reactants and products be given?
Sometimes the changes in state will affect how the reaction works or even if it will work at all.
What is the criteria in terms of temperature changes for exothermic and endothermic reactions?
Endothermic reactions draw heat from the reactants / products and the environment, so they tend to get cooler as the reaction proceeds. Exothermic reactions release heat to the reactants / products and the environment, so they tend to get hotter as the reaction proceeds.
What is a change that has the same substances as reactants and products?
It is a change in state. For instance, water may undergo boiling to form water vapour. The reactants and products are chemically the same, which is H2O. Another example would be the sublimation of ammonium chloride, where it changes directly from a solid to a gas.The change from reactants to products is called as a chemical reaction. According to the key reaction involved there are several types of reactions. For example, an acid and a base undergo a neutralization reaction to produce a salt and water as products.
What is true of a dynamic equilibrium?
When the concentration of the reactants is equal to the concentration of the products and does not change over time, the system has reached dynamic equilibrium. Dynamic equilibrium means that the reaction is still occurring and does not stop. The reaction never reaches completion, because the reverse reaction is moving at the same rate as the forward reaction. The products and reactants are balanced. The reactants are producing at the same speed that the products are changing back into the reactants. When a reaction is in dynamic equilibrium, it is hard to tell that a reaction is occurring. There is no net change in the concentration of the products or reactants because both forward and reverse reactions are moving at the same rate.
What happens to the reactants in a chemical reaction?
Put casually, they react with each other to form products. e.g. Reactants A & B form products C & D A + B = C + D
Does taking water out of an equilibrium reaction change the equilibrium constant?
No, the equilibrium constant is independent of concentration as long as the ratio of products and reactants remains as is. It can be effected by anything that would influence the ratio of products and reactants, such as changes in temperature or the addition of a catalysis.
What do you need in order to have a chemical reaction?
cell membrane
In a chemical reaction a catalyst changes the 1.potential energy of the products 2.potential energy of the reactants 3. heat of reaction 4.activation energy?
4. activation energy
