A reactant is something that reacts with another thing(s) in a word equation to make something else (the things made are the 'products'). So an example is:
CARBON + OXYGEN -> CARBON DIOXIDE + WATER
Carbon and oxygen are the reactants and carbon dioxide and water are the products.
This word equation as a symbol equation is:
C + O2 -> CO2 + H20

∙ 12y agoIf A and B combine to form C, then you say:
A + B => C
In this case, A and B are the reactants and C is the product.

What tells the story of a chemical reaction?
The written statement that shows a chemical reaction is called an "equation". The representation of each reactant is called its chemical formula.
What information in a balanced chemical equation shows how many moles of a reactant are involved in the reaction?
The coefficient (not a subscript or superscript) placed immediately before the formula of the reactant in the equation shows how many moles of a reactant are involved in the reaction. If there is no explicit coefficient, a value of 1 for the coefficient is assumed. The coefficient in front of the molecule tells its relative number of moles.
What is the reactant of H2O?
The reactants of H2O are, of course, Hydrogen and Oxygen, but the chemical equation is not as simple to understand.The chemical equation of water is: H4+O2 ---> 2H2OIt is complicated to understand, but the O has to be changed to O2 in the reactants side due to the H2, which was changed to H4 in order to balance out the equation.
After a chemical reaction starts when will a chemical reaction end?
When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.
Why is a catalyst written above the arrow in a chemical equation rather than with the reactants?
The enzyme is written above the arrow of the chemical equation because it is involved in the reaction without being changed by it or used up in the reaction. It is not a reactant or a product.
What is the chemical equation shown is a reactant?
Reactants are to the left in a chemical equation.
What is the first chemical in the chemical equation called?
The first reactant.
Each substance on the left side of the arrow in a chemical equation is a?
Reactant
what reactant has the smallest coefficient in a balanced chemical equation?
It depends on the equation.
What is a chemical equation in which both the reactant and product have an equal?
blananced equation
Which of the molecules in this chemical equation shown is a reactant?
CO2
What information In a balanced chemical equation shows how many moles of a reactant are involved in the reactant?
In a balanced chemical equation the number of molecules or atoms are specified.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
Is the substance to the right of the arrow in a chemical equation called a reactant?
No, on the right of the arrow in a chemical reaction is called a product. The reactant is on the left.
What information in a balanced chemical equation shows how many moles of a reactant are involed in the reaction?
The number before the chemical formula of the reactant.
Where are the reactant in a chemical equation located?
On the left side of the arrow
Where are the reactant located in chemical equation?
On the left side of the arrow
