What information are conveyed by a balanced chemical reaction why is it necessary to balanced a chemical equation?
A balanced chemical equation conveys the correct molar ratios of reactants and products in a reaction. Balancing a chemical equation upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed.
What information does coefficients provide in a balanced chemical equation?
Type your answer here... The coefficients give the molar ratio of the reactants
What term expresses the ratio of moles of reactants and products according to the coefficients in the balanced chemical equation?
molar (Or mole) ratio
How many grams of ethylene as needed to react with 0.0126 mole of water?
To determine the grams of ethylene needed to react with 0.0126 mole of water, you need to use the balanced chemical equation for the reaction between ethylene and water. Once you have the balanced equation, use the molar ratio between ethylene and water to convert moles of water to moles of ethylene. Then, use the molar mass of ethylene to convert moles of ethylene to grams of ethylene.
What is the sum of the atomic masses in a molecule?
Molecular mass.
How is the law of conservation of mass shown by a balanced equation?
In stoichiometry, the equation is balanced by using molar ratios. Because each item on either side of the equation has a specific molar mass, it can be demonstrated that all mass is conserved through the chemical reaction.

If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.

Is the following chemical equation balanced agno3 nacl 4agcl nano3?
The balanced equation is AgNO3 + NaCl --> AgCl + NaNO3. No coefficients are needed because everything bonds in a 1:1 molar ratio.

What term expresses the ratio of moles of reactants and products according to the coefficients in the balanced chemical equation?
molar (Or mole) ratio
What are the molar masses of pbBr2?
The molar mass of PbBr2 is 367.008 g/mol
Why must a chemical equation be balanced to solve stoichiometry problems?
Because chemical reactions take place in molar ratios. The number of moles of each kind of atom has to be the same on both sides of the equation.
How do you determine the stoichiometry of a reaction?
To determine the stoichiometry of a reaction, you must first write out a balanced equation describing the reaction and then use the coefficients of this statement to represent molar ratios.
Is defined as the sum of the atomic masses in the molecule?
This is the molar mass.
How many mole h2o have in this reaction caco3 plus 2hcl---cacl2 co2 h2o?
Molar ratio's in this balanced equation: 1 + 2 --> 1 + 1 + 1 (H2O) respectively
