What do the coefficients in a balanced chemical equation tell you about the reactants and products?

27
The coefficients of a balanced chemicalequation tell us the relative number of moles of reactantsand products. In solving stoichiometric problems, conversionfactors relating moles of reactants to moles of productsare used. In mass calculations, the molar mass is needed toconvert mass to moles.


Likewise, people ask, what do the coefficients in a balanced equation tell us mark all that apply?

coefficients are important to prove the law ofconservation of mass. The coefficients in a balancedchemical equation indicate the relative number of moles ofreactants and products. By multiplying the # of moles of thereactants by the mole ratio. You can determine the number ofmoles of the product.

Secondly, why must chemical equations be balanced choose all that apply Choose all that apply in a balanced chemical equation the coefficients in front of each reactant and product allow us to predict how much reactants are required to form a given amount of products in a balanced chemical equation the coefficients? In a balanced chemical equation, the coefficients infront of each reactant and product allow us to predict whetherthe given reaction is possible or not. In a balancedchemical equation, the coefficients in front of each reactant andproduct allow us to predict whether the reactionrequires a catalyst or not.

Hereof, what information about a chemical reaction is derived from the coefficients?

Chemical reactions are balanced by addingcoefficients so that the number of atoms of each element isthe same on both sides. Stoichiometry describes the relationshipbetween the amounts of reactants and products in areaction.

How does a balanced chemical equation show relationships between the reactants and products?

Stoichiometry is exactly that. It is thequantitative relation between the number of moles (andtherefore mass) of various products and reactants ina chemical reaction. Chemical reactions must bebalanced, or in other words, must have the same number ofvarious atoms in the products as in thereactants.

What is the importance of coefficients in a balanced equation?

In a balanced chemical equation, the totalnumber of atoms of each element present is the same on both sidesof the equation. Stoichiometric coefficients are thecoefficients required to balance a chemicalequation. These are important because they relate theamounts of reactants used and products formed.

What is the importance of stoichiometry?

Answer and Explanation:
Stoichiometry is the study of elements andmeasures the quantity of reactants consumed or the quantity ofproducts produced in a chemical reaction. Stoichiometry isimportant as only by analyzing a chemical equation, we maycalculate the amount of substances consumed orproduced.

What is a stoichiometric equation?

Stoichiometric Coefficients
In a balanced reaction, both sides of theequation have the same number of elements. Thestoichiometric coefficient is the number written in front ofatoms, ion and molecules in a chemical reaction to balance thenumber of each element on both the reactant and product sides ofthe equation.

What are the two items that are always conserved in every chemical reaction?

Every chemical equation adheres to the law ofconservation of mass, which states that matter cannot be created ordestroyed. Therefore, there must be the same number of atoms ofeach element on each side of a chemicalequation.

How do you solve stoichiometry problems?

There are four steps in solving a stoichiometryproblem:
  1. Write the balanced chemical equation.
  2. Convert the units of the given substance (A) to moles.
  3. Use the mole ratio to calculate the moles of wanted substance(B).
  4. Convert moles of the wanted substance to the desiredunits.

What is stoichiometry and how does it relate to chemical reactions?

Stoichiometry expresses the quantitativerelationship between reactants and products in a chemicalequation. Stoichiometric coefficients in a balanced equationindicate molar ratios in that reaction. Stoichiometryallows us to predict certain values, such as the percent yield of aproduct or the molar mass of a gas..

What happens when a chemical equation is unbalanced?

According to the law of conservation of mass, when achemical reaction occurs, the mass of the products should beequal to the mass of the reactants. A balanced chemical equationoccurs when the number of the atoms involved in the reactantsside is equal to the number of atoms in the productsside.

What is conserved during a chemical reaction?

In a chemical reaction the total mass of all thesubstances taking part in the reaction remains the same.Also, the number of atoms in a reaction remains the same.The law of conservation of mass states that the total mass ofsubstances taking part in a chemical reaction isconserved during the reaction.

Can all chemical equations be balanced?

A balanced chemical equation tells you theamounts of reactants and products needed to satisfy the Law ofConservation of Mass. Basically, this means there are the samenumbers of each type of atoms on the left side of theequation as there are on the right side of theequation.

What is the actual yield of a reaction?

The actual yield is the quantity of a productthat is obtained from a chemical reaction. In contrast, thecalculated or theoretical yield is the amount of productthat could be obtained from a reaction if all of thereactant converted to product. Theoretical yield is based onthe limiting reactant.

What does it mean to simplify the chemical equation?

A balanced equation is an equation for achemical reaction in which the number of atoms for eachelement in the reaction and the total charge are the same for boththe reactants and the products. In other words, the mass and thecharge are balanced on both sides of the reaction.
