Basic chem

..... composed of extremely small particles, called

atoms.

• Element

• Molecule

• Compound

• Ion

..... is the total number of neutrons

and protons present in the nucleus of an atom of

an element.

• Mass number

• Atomic number

• Isotope

• electron

Which is the properties of gases

• Gases is the easiest form of matter to compress

• Gases not assume the volume and shape of their containers

• Gases will not immediately mix evenly and perfectly if placed in the same container

• They have much higher densities than liquids and solids

In the ideal gas equation (PV = nRT), the R value is

• 0,0821 L.atm/K.mol

• 0,821 L.atm/K.mol

• 0,00821 L.atm/K.mol

• 8,210 L.atm/K.mol

..... is defined as the ability to do work.

• Energy

• System

• Surrounding

• Enthalpy

..... which is the science that studies changes between heat and other forms of energy.

• Thermodynamics

• State function

• Enthalpy

• System

....., a bond in which two electrons

are shared by two atoms.

• Covalent bond

• Ionic bond

• Electronegativity

• Octet Rule

Geometric shape of the AB2E2 molecule

• Tetrahedral

• Bent

• Trigonal Pyramidal

• Distorted Tetrahedron

...... measures how fast a reactant is consumed or how fast a

product is formed.

• Rate of reaction

• Rate laws

• Activation energy

• Rate constant

..... describes the state in which the rates of forward and reverse reactions are equal and the

concentrations of the reactants and products remain unchanged with time.

• Chemical equiblirium

• Equilibrium constant

• Reaction qoutient

• Le Chatlier's principle
