The conversion of one or more reactants chemically to form one or more products is known as a chemical reaction. When the reaction gives out energy, it is an exothermic reaction. When the energy is taken in, it is an endothermic reaction. The four basic types of chemical reactions are synthesis, decomposition, single replacement, and double replacement. There are oxidation and reduction reactions where there is gain and loss of oxygen.
Chemical Exposures During Pregnancy
Genetic diseases may be more common in people whose pregnancies include high levels of chemical exposure and cause miscarriage, impairing the child's development.
