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.



What information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction?

The information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction is the number appearing immediately before the formula for the reactant in question in the chemical equation. This number is called a "coefficient".




What number describes how many molecules are involved in a chemical reaction?

In a balanced equation for the reaction, the coefficient appearing immediately before the formula for a reactant describes the number of moles of that reactant involved in the reaction shown by the equation.


In a chemical equation where is the reactant?

at the beginning of the equation


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 chemical equation shown is a reactant?

Reactants are to the left in a chemical equation.


What does reactant mean in a chemical equation?

A reactant is a starting material that is about to undergo a chemical change. When looking at the written chemical equation, the reactants are to the left of the central arrow.


What equation has water as a reactant in the chemical reaction?

Any chemical equation in which water is one of the compounds combined to form the product has water as a reactant.




Describe in words a balanced chemical equation?

Balanced Chemical Equation is an equation in which the number of moles of reactant is equal to the moles of product .



The products of a chemical reaction are?

1. A chemical equation is a concise shorthand expression which represents the relative amount of reactants and productsinvolved in a chemical reaction. The skeleton equation indicates that two hydrogen atoms react with two oxygen atoms on the reactant side of the equation.


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."


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 part of chemical equation allows us to determine how much product you can get from a known amount of reactant?

The reaction equation gives the RATIO of moles reactant to moles product. With known molar mass the (mass) yield can be calculated. (Of course other reactants are to be in excess! for complete reaction of the reactant involved for this yield)


Where is a reactant in a chemical equation?

Reactants are on the left side of a chemical equation, at least in countries where one reads from left to right.


Does an equation indicates the number of atoms of each product and each reactant involved in a reaction?

Not quite. A properly balanced an equation indicates the number of atoms of any elemental product and any elementalreactant involved in a reaction, along with the number of molecules of any molecular compound product and any molecular compound reactant involved in the reaction. The original sentence is deficient because in any chemical reaction, there must be at least one non-elemental product or reactant.


What are 5 key words in a chemical change?

These are: reaction, chemical formula, reactant, product, chemical equation.
