Do you always need more than one reactant or more than one product to have a chemical reaction?

A simple definition of a chemical reaction is a reaction in which chemical bonds are broken and/or formed.
Under the right conditions (temperature, pressure and catalyst) the following reaction may run:
2CH4 -> C2H6 + H2
Although in this case two molecules of the same reactant was needed, only one reactant was needed. So, the direct answer to your question is no.

∙ 14y agoNot necessarily. While that is the most common general setup of a chemical reaction, there are others. Synthesis reactions have two reactants that combine to form a single product, like in the reaction 2H2+O2-->2H2O*. Also, there are decomposition reactions, such as the decomposition of hydrogen peroxide: 2H2O2-->O2+2H2O.
*Important note: this is not the true reaction for the formation of water. It is an overall reaction comprised of smaller, sub-reactions that must take place for this to be possible. Simply mixing Hydrogen gas with Oxygen gas will not produce water. NO REALLY DUMB KID

∙ 12y agoBy definition a reactant is something that reacts with something. So it will need something to react with. It's like asking if you could have just one boxer in a boxing match.

YES!!!
The reaction starts with reactants and finishes with products.

What are reactants and products?
Reactants (or 'substrates') are two or more elements/ compounds that chemically interact to form a new substance. They are the starting materials for a reaction and are always found at the left side of a chemical equations.A reactant is one of the inputs in a reaction, that get changedThe word reactant is used in chemistry. A substance that has a reaction and undergoes a change is considered reactant.
In a balanced chemical reaction the total mass of the products always equals the total what?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
Is formation of a gas is a chemical change?
The formation of gas is:- a chemical process if the gas is the product of a chemical reaction- a physical process if the gas is the product of a change of phase as sublimation and vaporization
In any chemical reaction the quantities that are preserved are?
In any chemical reaction the quantities that are conserved are mass and number of atoms. After the correct formula for a reactant in an equation has been written, the formula should not be changed.
What is always conserved in a chemical reaction?
mass
What is the difference between a reactant and a product in a chemical reaction?
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
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!
What happens to a chemical reaction when the limiting reactant is completely used up?
Limiting reactant is the one that limits the rate of the reaction. It is always supplied in adequate amount so that there is enough for the reaction to carry out to obtain the desired products. under ideal cases, When the reaction reaches completion there will be no limiting reactant.
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
How do you identify which is the reactant and which is the product?
In a chemical reaction equation the reactants are the ones in the left side of theequal or arrow sign, and the products are the ones on the right side.i.e., Reactants → Products

What is always a reactant in a combustion reaction?
Oxygen
What is always formed during a chemical reaction?
a chemical reaction always converts reactants to products. Products are always formed otherwise it's not considered a chemical reaction.
What kind of reaction is oxygen always the reactant?
Fire
If one product a chemical reaction is removed the reaction?
Removing product generally shifts the equilibrium to the right. Not always, though; it depends on the details.
How does the chemical energy of the reactants compare to the chemical energy of the products?
the reactants always start at the line but the product would either be over or under the line depending on the reaction.
In a balanced chemical reaction the total mass of the products always equals the total what?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
