Study Notes
Chemical Reactions and Equations
- There are five general types of chemical reactions: synthesis, decomposition, single displacement, double displacement, and combustion reactions.
Balancing Chemical Equations
- To balance a chemical equation, the number of atoms of each element must be equal on both the reactant and product sides.
- This is achieved by adding coefficients (numbers in front of formulas of reactants or products) to the equation.
Law of Conservation of Mass
- The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction, only transformed from one substance to another.
- This means that the total mass of reactants is equal to the total mass of products in a chemical reaction.
Chemical Reactions and Equations
- A chemical reaction is a process in which one or more substances are converted into new substances.
- A chemical equation is a representation of a chemical reaction using chemical formulas and symbols.
- The equation shows the reactants (starting materials) on the left and the products (resulting substances) on the right.
Stoichiometry and Balanced Equations
- The stoichiometry of a chemical reaction is the quantitative relationship between reactants and products.
- The coefficients in a balanced chemical equation represent the mole ratios of reactants and products.
- These coefficients are used to calculate the amounts of reactants required or products formed in a reaction.
