What is stoichiometry?

Stoichiometry is a branch of chemistry that deals with the calculation of relative quantities of reactants and products in chemical reactions based on the principles of conservation of mass. It involves determining the molar ratios of substances in a balanced chemical equation to accurately predict the amount of products formed or reactants needed in a chemical reaction.

What is a balanced chemical equation?

A balanced chemical equation is a representation of a chemical reaction where the number of atoms of each element is the same on both the reactant and product sides. This is achieved by adjusting the coefficients of the reactants and products to ensure that the law of conservation of mass is satisfied, meaning that atoms are neither created nor destroyed during a chemical reaction.

How do you determine the stoichiometric coefficients in a balanced equation?

To determine the stoichiometric coefficients in a balanced equation, you first write the chemical equation with the correct formulas for the reactants and products. Then, balance the equation by adjusting the coefficients of the compounds involved until the number of each type of atom is the same on both sides of the equation. This involves using integer values to balance the atoms and ensuring that the law of conservation of mass is satisfied.

What is a molar ratio?

A molar ratio is a ratio that compares the amounts in moles of two substances in a chemical reaction. It is used to indicate the relative quantities of reactants and products involved in a reaction and is based on the coefficients of the balanced chemical equation. Molar ratios help in determining the stoichiometry of a reaction and are crucial in calculating the amounts of reactants needed or products produced in a chemical reaction.

How do you calculate the number of moles of a substance from its mass?

To calculate the number of moles of a substance from its mass, you need to divide the given mass of the substance by its molar mass. The formula is: moles = mass (in grams) / molar mass (in g/mol). By using this formula, you can determine the amount of moles present in a given mass of a substance.

How do you calculate the number of particles (atoms, molecules, etc.) from the number of moles?

To calculate the number of particles from the number of moles, you can use Avogadro's number, which is 6.022 x 10^23 particles per mole. Simply multiply the number of moles by Avogadro's number to find the number of particles. For example, if you have 2 moles of a substance, you would multiply 2 moles by 6.022 x 10^23 particles/mole to get 1.2044 x 10^24 particles.

What is the limiting reactant in a chemical reaction?

The limiting reactant in a chemical reaction is the reactant that is completely consumed first and limits the amount of product that can be formed. It determines the maximum amount of product that can be produced in the reaction.

How do you calculate the theoretical yield of a reaction?

To calculate the theoretical yield of a reaction, you typically start with the balanced chemical equation for the reaction. Next, you determine the limiting reactant by comparing the amounts of each reactant to their stoichiometric coefficients. Then, use the stoichiometry of the balanced equation to calculate the theoretical yield based on the limiting reactant. Finally, convert the amount of limiting reactant consumed to the amount of product formed using the mole ratio in the balanced equation.

What is percent yield and how is it calculated?

Percent yield is a measure of the efficiency of a chemical reaction or process, indicating the proportion of the theoretical yield that is actually obtained in practice. It is calculated by dividing the actual yield by the theoretical yield and then multiplying by 100 to express the result as a percentage. The formula for percent yield is: (actual yield / theoretical yield) x 100%.

How can stoichiometry be used to determine the amount of excess reactant or the amount of product formed in a reaction?

In stoichiometry, the balanced chemical equation is used to establish the mole ratio between reactants and products. By comparing the actual amount of reactants used in a reaction to the amounts required by the stoichiometry of the balanced equation, one can determine the limiting reactant and the amount of excess reactant. This information can then be used to calculate the theoretical yield of products that should be formed. The actual yield of the product can be compared to the theoretical yield to determine the efficiency of the reaction.
