5.12 Unit Test Chemical Reactions
What Causes Chemical Reactions?
Chemic 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 move and sharing of electrons between atoms without any modify to the nuclei.
While there are multiple types of chemic bonds, the most common bonds are ionic or covalent. An ionic bond occurs when an atom takes an electron from some other cantlet, causing chemical reactions, such every bit those with sodium and chlorine to grade table common salt. Covalent bonds occur when atoms share electrons, causing chemical reactions such equally that between hydrogen and oxygen to grade h2o.
The chemical changes in reactions are the transformation of the reactants into one or more than products, which have unlike properties than the original reactants. Chemical changes occur at a ready reaction rate based on the temperature and chemical concentration involved, and typically end when one of the reactants is consumed, the required energy is no longer supplied or the reactant mixture reaches chemical equilibrium. In equilibrium the reaction is stable, but reactions may be connected by removing products from the reaction mixture, increasing the temperature or applying pressure.
