Jahzeel Morales AP Chemistry December 12‚ 2014 Determination of the Molar Mass of Volatile Liquids Theory: Molar masses‚ can be seen and used daily in chemistry. In this lab‚ the ideal gas law helps determine and evaluate the molar mass of gases and volatile liquids. The ideal gas law compares four properties of a gas which include pressure‚ volume‚ moles‚ and temperature. During this experiment‚ the moles would be unknown‚ in effect the student must use a substance mass divided by its molar mass

1 Class XII: Chemistry Chapter 1: The Solid State Concept 1. Solid: Solid is a state of matter in which the constituting particles are arranged very closely. The constituent particles can be atoms‚ molecules or ions. Properties of solids: a. They have definite mass‚ volume and shape. b. Intermolecular distances are short and hence the intermolecular forces are strong. c. Their constituent particles have fixed positions and can only oscillate about their mean positions. d. They are incompressible

• The equilibrium law DYNAMIC EQUILIBRIUM forward A +8 reaction ""r=====~’~ reverse reaction Most chemical reactions do not go to completion. Once some products are formed the reverse reaction can take place to reform the reactants. In a closed system the concentrations of all the reactants and products will eventually become constant. Such a system is said to be in a state of dynamic equilibrium. The forward and reverse reactions continue to occur‚ but at equilibrium
