A coefficient stands for how many moles are in that element or compound. For example the reaction: 2LiOH+H2SO4->Li2So4+2H20 the coeficient is a 2 in front of LiOH meaning u need 2 moles of that to equal and balance out the other side.

The coefficients are the numbers written in front of the chemical formulas in a chemical equation, and tells how much of a certain substance is involved in the reaction. When there is no number, it is understood to be one. For example, the following equation, which represents the combustion of methane (CH4), could be read in a couple of different ways.

CH4 + 2O2 --> CO2 + 2H2O

One molecule of methane plus two molecules of oxygen produces one molecule of carbon dioxide plus two molecules of water.

or

One mole of methane plus two moles of oxygen produce one mole of methane plus two moles of water.

What information in a balanced chemical reaction 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 information in a balanced chemical equation shows how many moles of REACTANT ARE INVOLVED IN The reaction?

What is a reaction quotient?

A reaction quotient is a fraction with product concentrations in the numerator and reactant concentrations in the denominator - with each concentration raised to a power equal to the corresponding stoichiometric coefficient in the balanced chemical equation.

It tells you the number of molecules or number of moles of each substance.


Why is Fe balanced with coefficient of 3 instead of a subscript of 3?

The subscript is mentioned only in a chemical formula.3 FeCl3 in a chemical reaction is not similar to Fe3O4 in a chemical formula.


What is the significance of rate constant?

A coefficient of proportionality relating the rate of a chemical reaction at a given temperature to the concentration of reactant (in a unimolecular reaction) or to the product of the concentrations of reactants.


The number that tells how many molecules of a particular substance take part in a chemical reaction is?

When writing a BALANCED Reaction equation , it is the extreme left number(Molar ratio) that indicates the number of molecules reacting. e.g. H2SO4 + 2KOH = K2SO4 + 2H2O The molar ratios are 1:2::1:2 We can re-write this equation as H2SO4 + KOH + KOH = K2SO4 + H2O + H2O As you can see the 'KOH' and the H2O ' are written out twice.. So in order to eliminate this repetition we place a coefficient ( molar ratio) to the left of the given molecule.
