ATOM Basic unit of Matter Gk. “atomos” – indivisible
Proton – (+) charge Neutron- No charge Electron- (-) charge
Found in the NUCLEUS…. Kaya they are collectively called NUCLEONS…. xD
GUYS TAKE NOTE that it is 1,836 times lighter
than a proton; thus, the weight is
negligible, okie?

CHEMICAL BONDING - Forces that hold atoms together- All elements try to achieve the configuration of the NOBLE GASES
* OCTET RULE – atoms become stable when the valence e- will complement fully the valence shell
TYPES OF CHEMICAL BONDING:
1. Complete e- transfer (a.k.a. IONIC BOND)- bond formed by a metal and a non-metal- ELECTROSTATIC BOND
2. Sharing of e- (a.k.a. COVALENT BOND)- 2 nonpolar (similar atoms) equal e- sharing- 2 polar (dissimilar atoms) unequal e- sharing

GAS LAWS BOYLE’S LAW —Volume is inversely proportional to pressure
CHARLES’ LAW— Volume is directly proportional to temperature (Kelvin)
AVOGADRO’S LAW —Volume is directly proportional to moles
DALTON’S LAW OF PARTIAL PRESSURE- States that the pressure exerted by a mixture of gases is the sum of the partial pressures that each gas in the mixture exert individually
![Page 37: General Chemistry and Inorganic Pharmaceutical Chemistry Module 1 Pharmacist licensure exam review](https://reader033.fdocuments.us/reader033/viewer/2022061409/58744b791a28abd53e8b4c43/html5/thumbnails/37.jpg)
GAS LAWS IDEAL GAS LAW
GRAHAM’S LAW —The rate of the effusion of two gases (and diffusion) are inversely proportional to the square roots of their densities providing the temperature and pressure are the same for the two gases. DIFFUSION=gradual mixing of molecules of one gas with the molecules of
another gas by virtue of their kinetic properties EFFUSION=passage of a gas under pressure through a small opening
![Page 38: General Chemistry and Inorganic Pharmaceutical Chemistry Module 1 Pharmacist licensure exam review](https://reader033.fdocuments.us/reader033/viewer/2022061409/58744b791a28abd53e8b4c43/html5/thumbnails/38.jpg)
SOLUTIONS Solute + Solvent Factors affecting solubility:
1. Nature of Solute and Solvent2. Temperature: Temp = Solubility (MOST OF THE TIME)
3. Pressure: Pressure = Solubility of gas in Liquid – (HENRY’S LAW)
EXCEPTIONS: Exothermic: Inc in Temp = Dec Solubility Solution of gas in liquid: Inc in Temp = Dec
Solubility
REMEMBER that GAS and Ca(OH)2 are the most common substances that dissolve in COLD TEMPERATURE

CHEMICAL THERMODYNAMICS Thermodynamic System- part of the universe
isolated from the rest by a boundary
“Surrounding” = Everything outside
TYPE OF SYSTEM ALLOWS EXCHANGE OF
Open (Non-conservative)
Matter & Energy
Closed (Conservative)
Energy ONLY
Isolated (Adiabatic) No matter, No energy
![Page 40: General Chemistry and Inorganic Pharmaceutical Chemistry Module 1 Pharmacist licensure exam review](https://reader033.fdocuments.us/reader033/viewer/2022061409/58744b791a28abd53e8b4c43/html5/thumbnails/40.jpg)
LAW OF THERMODYNAMICS 1st Law of Thermodynamics - Heat and work are forms of
energy transfer. Energy is invariably conserved, however the internal energy of a closed system may change as heat is transferred into or out of the system or work is done on or by the system.
2nd Law of Thermodynamics - An isolated system, if not already in its state of thermodynamic equilibrium, spontaneously evolves towards it. Thermodynamic equilibrium has the greatest entropy among the states accessible to the system.
3rd Law of Thermodynamics - The entropy of a system approaches a constant value as the temperature approaches zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has. Specifically, the entropy of a pure crystalline substance at absolute zero temperature is zero

CHEMICAL EQUILIBRIUM- It is a STATE at which the amount of Reactant and
Products present are CONSTANT
LE CHATELIER’S PRINCIPLE- if a system is subjected to stress, the
system will adjust to relieve the stress
Stress: Concentration Pressure and Volume Temperature Catalyst – causes NO SHIFT in Equilibrium (PLS. REMEMBER )
