Acid rain is formed when nitrogen oxides or sulfur oxides in the atmosphere react with suspended water droplets and produce acids. The chemical reaction equation for the production of acid rain resulting from sulfur oxides is: SO2 + HOH - H2SO3. The reaction equation for acid rain produced from nit

Chemical reactions occur when two molecules collide with each other in a certain orientation and amount of force, which causes a chemical change due to the breaking and forming of the bonds between the atoms. Bonds are broken and formed due to the movement and sharing of electrons between atoms with

The molecules of one reactant are combined with those of another reactant to form a new substance during a chemical reaction. As the chemical bonds are broken, the positions of electrons change, resulting in a product with properties that are different from the properties of the reactants. Various t

It is important to balance chemical equations because there must be an equal number of atoms on both sides of the equation to follow the Law of the Conservation of Mass. This chemical law states that in order for the equation to be correct, "An equal quantity of matter exists both before and after t
