A chemical reaction is a process in which one or more substances (reactants) are transformed into one or more new substances (products) with different properties. This transformation involves breaking and forming chemical bonds between atoms.
The main types of chemical reactions are synthesis, decomposition, single displacement, double displacement, combustion, and acid-base reactions. These are classified based on the type of reactants and products involved in the reaction.
To balance a chemical equation, you need to make sure that the number of atoms of each element on the reactant side is equal to the number of atoms of that element on the product side. This can be achieved by adjusting the coefficients in front of each compound in the equation.
The rate of a chemical reaction can be affected by factors such as temperature, concentration of reactants, presence of a catalyst, surface area of reactants, and pressure (for reactions involving gases). These factors can either increase or decrease the rate of the reaction.
Stoichiometry is the calculation of the quantities of reactants and products involved in a chemical reaction. It is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Stoichiometry is used to determine the amount of products that can be obtained from a given amount of reactants, and vice versa.
