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

What tells the story of a chemical reaction?
The balanced chemical equation for a reaction tells the story of a chemical reaction by showing the reactants that are consumed and the products that are formed. It also provides information on the stoichiometry of the reaction, including the ratios of reactants and products involved.
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.
Is magnesium a reactant or product?
It depends on the chemical reaction taking place.magnesium + oxygen -> magnesium oxideIn equation 1 it would be a reactant.magnesium oxide -> magnesium + oxygenIn equation 2 it would be a product.If magnesium is on the left-hand side of the equation it is a reactant.If magnesium is on the right-hand side of the equation it is a product.From Wikipedia:"The substances initially involved in a chemical reaction are called reactants. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants."
If 100 g of CuS and 56 g of O2 are available which is the limiting reactant?
To determine the limiting reactant, first calculate the moles of each reactant by dividing the given mass by their respective molar masses. Then, determine the mole ratio between CuS and O2 in the balanced chemical equation. The reactant that produces fewer moles of product based on this ratio is the limiting reactant.
If one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction one can determine the mass of product D produced by using the?
Balanced chemical equation along with the stoichiometric ratios derived from that chemical reaction. A + B --> 2C mass of A * 1/molar mass of A = moles of A Moles of A * 2 moles of C/mole of A = moles of C Moles of C * molar mass of C = mass of C Also, you must think about limiting reagents, because if there is not enought reactant B to react with the amount of reactant A then the amount of reactant B will limit the production of product C!
What is the chemical equation shown is a reactant?
Reactants are to the left in a chemical equation.
what reactant has the smallest coefficient in a balanced chemical equation?
The reactant with the smallest coefficient in a balanced chemical equation is considered the limiting reactant because it limits the amount of product that can be formed.
Each substance on the left side of the arrow in a chemical equation is a?
Reactant
What is the first chemical in the chemical equation called?
The first reactant.
What is the reactant(s) in the chemical equation below?
The reactants in a chemical equation are the substances that are present at the start of a reaction and are used up during the course of the reaction. If you provide the specific chemical equation, I can help you identify the reactant(s).
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
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
What chemical equation has equal numbers of reactant and product atoms?
Any chemical reaction.
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.
In a chemical equation the limiting reactant .?
determines the amount of product that will form
What is the equation that has water as a reactant in chemical reaction?
An example of a chemical equation with water as a reactant is the reaction between hydrogen gas and oxygen gas to form water: 2H2 + O2 -> 2H2O.
