Key Concepts

Conservation of Mass

This principle states that in a closed system, the total mass of reactants equals the total mass of the products regardless of the chemical reaction. It is a fundamental concept in chemistry that underpins the balancing of chemical equations and ensures that mass is neither created nor destroyed during a reaction.

Chemical Equation Balancing

Balancing a chemical equation involves ensuring that the number of atoms of each element is the same on both the reactant and product sides of the equation. This practice reflects the conservation of mass and is crucial for accurately describing the proportions in which reactants combine and products form.

Stoichiometry

Stoichiometry is the calculation of the quantities of reactants and products in chemical reactions using the balanced equation. It helps in determining the relationships between the amounts of substances involved in the reaction, ensuring accurate computations of masses, moles, and volumes based on the reaction coefficients.

Molar Mass

Molar mass is the mass of one mole of a given substance, usually expressed in grams per mole (g/mol). It plays a key role in converting between the mass of a substance and the amount in moles, which is essential for undertaking stoichiometric calculations in chemical reactions.
