GENERIC NAME: enalapril. DRUG CLASS AND MECHANISM: Enalapril is a drug that is used for treating high blood pressure. It is in a class of drugs called angiotensin converting enzyme (ACE) inhibitors. ACE is an enzyme in the body that causes the formation of angiotensin II.
RECOMMENDED LESSONS: Chemical energy. Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by product (exothermic reaction) . Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.
To understand the difference between two types of reactions (exothermic and endothermic), we need to explore a couple of other concepts. In addition to kinetic energy (vibrational, rotational and translational motion), molecules also have potential energy. Potential energy is energy due to position and composition. It is stored in molecular bonds that exist within molecules (intramolecular); between different molecules (intermolecular), between different atoms of an element and finally within atoms. Example1 Show the intermolecular and intramolecular bonds in HCl.
