What is a coefficient in a equation?
The coefficients in a chemical equation represent the amount of moles of each substance involved in the reaction. On a smaller level, it also represents the amount of particles that have to collide or are produced in the reaction. Consider the following example: CH4(g) + 2O2(g) (arrow) 2H2O(l) + CO2(g) The coefficent behind oxygen in the reactants means that 2 molecules of oxygen have to collide with 1 molecules of methane to react. The coefficients in the products mean that this reaction produces 2 molecules of water and 1 molecule of carbon dioxide.
What are the two sides of a chemical equation called?
The side on the left of a chemical equation is the reactants, the chemicals consumed by the reaction. The side on the right is the product, the chemicals produced by the reaction.
Mass mass problems?
Mass-mass problems can be solved in various ways. You should start by writing a balanced equation for chemical reaction involved and eventually change the mass into moles which will facilitate the comparison and allow you to calculate the number of moles required.

How can you obtain third equation of motion from first equation?
The 1st and 3rd Equation of motion are the same, the force is zero. Thus 0 =force = Sum forces = action + reaction =0
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What do coefficients in a chemical equation represent?
Coefficients in a chemical equation represent the number of units of the formula immediately following the coefficient that are involved in the balanced equation for the reaction.
What information about a chemical reaction is derived from the coefficients in a balanced equation?
Coefficients are used to represent multiple molecules of formula units.
How do the coefficients in a balanced equation compare quantites of two substances?
These coefficients show the number of molecules involved in the chemical reaction.
How does the coefficients a balanced equation compare quantities of two substances?
In a balanced equation, the coefficients show the mole ratio of the different substances. That is, it shows how each substance taking part in the reaction is related on a mole to mole basis.
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 can you calculate if you know the concentration of a reaction's products and reactants as well as the coefficients of each in the balanced equation?
the equilibrium constant
What is the importance of coefficients in a balanced chemical equation?
Coefficients are imortant in a balanced chemical reaction, because it shows you how much of that chemical is reactanting, and also how much is being produce to form the products.
What is a balanced chemical equation why should the chemical equation be balanced?
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
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.
What information do the coefficients of a of a balanced equation give about the reactants?
These coefficients show the number of molecules (and the amount of substance) involved in the chemical reaction.
