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

The 'BIG' number to the left of a chemical substance is the 'molar ratio'. e.g. 2NaOH(aq) + H2SO4(aq) = Na2SO4(aq) + 2H2O(l) In words ' Two moles of sodium hydroxide react with one mole of sulphuric acid, to produce one mole of sodium sulphate and two moles of water. NB The number '1' is never shown as a molar ratio. When no number is shown, read it as '1'(one).


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.


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

These data are given by the correct coefficients in the chemical equation.


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

This is the number before a chemical compound.

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 information in a balanced chemical equation shows how many miles of a reactant are involved in the reaction?

A balanced chemical equation does not provide information on the physical amount or quantity of reactants involved in a reaction, such as miles. The coefficients in a balanced chemical equation represent the mole ratio of reactants and products, not physical quantities like miles. To determine how many moles or amount of reactant is involved in a reaction, one would need to use stoichiometry calculations based on the coefficients in the balanced equation and known quantities.


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

The coefficient (the number in front of the reactant) tells you the number of moles involved.


What is a balanced chemical equation showing the formula of each reactant and product in the reaction?

Sure, could you please provide the reaction you would like to see a balanced chemical equation for?


What gets written into a chemical reaction when it is balanced?

In a complete and correctly balanced chemical equation you will have the coefficients for each reactant and product indicating the mole ratios as well as the phases of each reactant and product.


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.


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.
