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.

What is the difference between a word equation a formula equation and a chamical equation?
A chemical formula is the way a particular chemical (element or compound) is represented using the letters given in the Periodic Table. For example, the chemical formula of oxygen is O2 and the chemical formula of caron dioxide is CO2A word equation describes a chemical reactionusing the names of chemicals only. For instance, the word equation for respiration is:glucose + oxygen => carbon dioxide + waterA formula equation also describes a chemical reaction, but uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:CH4 + 2O2 => CO2 + 2H2O
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
How do the coefficients in a balanced equation compare quantites of two substances?
The coefficients in a balanced equation represent the relative number of moles of each substance involved in a chemical reaction. By comparing the coefficients of the substances in the balanced equation, you can determine the mole ratios between them. This allows you to calculate the amounts of substances consumed or produced in the reaction.
What information can you determine from the coefficients in this balanced chemical equation?
The coefficients in a balanced chemical equation represent the relative amounts of each substance involved in the reaction. They indicate the mole ratios of the reactants and products, which can be used to determine the stoichiometry of the reaction. The coefficients help to show the conservation of mass and atoms in the 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 indicates how much of each reactant will be used up in a reaction?
the coefficients of a balanced reaction
How does the coefficients a balanced equation compare quantities of two substances?
The coefficients in a balanced chemical equation represent the ratio of moles of reactants and products involved in a reaction. This allows for the comparison of the amounts of different substances involved in the reaction. The coefficients provide a way to understand the stoichiometry of the reaction and ensure that matter is conserved.
Are coefficients equal in a balanced chemical equation?
No, coefficients in a balanced chemical equation represent the relative amounts of each reactant and product involved in the reaction. Coefficients can be different for each substance in the equation based on the stoichiometry of the reaction.
What information about a chemical reaction is derived from the coefficients in a balanced equation?
The coefficients in a balanced chemical equation provide the mole ratios of reactants and products involved in the reaction. This information is used to determine the amount of each substance consumed and produced in the reaction and to calculate the theoretical yield of a product.
How can you tell the mole ratio of substances in a balanced equation?
The mole ratio of substances in a balanced equation is determined by the coefficients of the reactants and products in the equation. These coefficients represent the number of moles of each substance involved in the reaction. By looking at the ratios of these coefficients, you can determine the mole ratio of the substances involved.
How do you determine the stoichiometry of a reaction?
To determine the stoichiometry of a reaction, you must balance the chemical equation by adjusting the coefficients of the reactants and products so that the number of each type of atom is the same on both sides. This helps in determining the mole ratio of reactants and products involved in the reaction. The coefficients in the balanced equation represent the stoichiometry of the reaction.
What correctly gives the best coefficients for the reaction below N2H4 plus H2O2 plus N2 plus H2O?
The balanced equation for the reaction is: N2H4 + H2O2 -> N2 + H2O The coefficients for the balanced equation are: 1 N2H4 + 1 H2O2 -> 1 N2 + 2 H2O
What information does the coefficients provide in a balanced equation?
The coefficients in a balanced chemical equation represent the relative amounts of reactants and products involved in the reaction. They provide information about the mole ratio between the substances participating in the reaction.
