the transfer of energy from molecule to molecule is called

. The ATP molecules transfer energy to other biological molecules. ATP (adenosine triphosphate) is an energy rich compound having three phosphate group attached to a nucleoside of adenine (a nitrogen base), called adenosine (adenine + pent..

Average kinetic energy of a molecule is The total kinetic energy of all the molecules is The average speed is somewhat smaller than the rms speed. It can be shown th..

The smallest particle of an element, which may or may not have independent existence is called an atom, while the smallest particle of a substance which is capable of independent existence is called a molecule. Molecules are classified as homoatomic and heter..

An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively or negatively charged ion respectivel..

Molecules of Compounds - A molecule of a compound consists of two or more atoms of different elements joined together in a fixed ratio. Examples: CuSO 4 contains Cu - 1 atom, S - 1 atom, O - 4 atoms A chemical formula represents the composition of a molecule of the sub..

Atoms and Molecules - Laws of Chemical Combination With the development of more scientific ideas on elements, compounds and mixtures, people began to probe into how and why substances react. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by descr..

Atoms and Molecules - Summary The law of conservation of mass states that the masses of the reactants and products remain unchanged. The law of constant proportions states that all pure specimens of a compound always contain the same elements combined together in the same proportion by we..

The Atom - When scientists started exploring matter, they realised that matter can be divided into smaller and still smaller particles. What was the ultimate particle like? They discovered that the smallest particle of an element that maintains its chemical identity through all chemical and phys..

Formation of Molecule Atoms of most of the elements do not exist independently. They either form molecules or ions. An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively or negatively charged ion res..

Asymmetric and Chiral Molecules - An object or molecule is not symmetrical or is asymmetrical when it doesn't have any element of symmetry. Chiral molecules are asymmetrical in nature. However some symmetrical molecules are also chiral when their symmetry is ..
