Inorganic Chem Reviewer Flashcards
One of the fundamental properties of any matter.
Density
What is the formula of density?
P= m/v
What is the SI unit of density? (Checimal and non-chemical-setup).
In chemical setup, g/cm3, non-chemical setup kg/m3
What is the density of 30 C?
0.9957g/mL
What is the density of 25 C?
0.9970g/mL
What is the density of 4 C?
1.0000g/mL
What is the density of 0 C?
0.9998g/mL
How is the volume of liquid can be easily determined?
It can be determined using calibrated cylinder but in laboratory setting, it can be determined in a graduated cylinder.
Can be determined by direct measurement provided that the solid has a regular geometrical shape, such as a cube or a cylinder.
Volumes of Solid
Such as a small rock or a small chunk of metal are determined by liquid volume displacement.
Volume of irregularly shaped solids
Closeness of a measurement to its true value.
Accuracy
How a measurement or process can repeat the
same value.
Precision
What is C?
Speed of light (~3.08x108m/s)
What is λ?
Wavelength
What is f?
Frequency
How is a quantum energy can be released?
Whenever an electron decays from a greater amount of energy to a smaller amount of energy.
When are the colors created?
When atoms with different energy levels collide.
The first to propose that the outermost electron of an atom.
Gilbert N. Lewis
Are responsible for the formation of molecular bonds.
Valence electrons
Shows how atoms would share electrons to fill eight (8) electrons in its outermost shell to form covalent bonds also known as Octet Rule.
Lewis Dot Structure
Suggests that electron pairs around an atom will assume a position that minimizes the repulsion between electrons.
Valence Shell Electron Pair Repulsion (VSEPR)
A process wherein reactants (or starting materials) are converted into products.
Chemical reaction
Two or more atoms or compounds in this type of reaction combine to form a product.
Combination or synthesis.
This type of reaction is a breakdown of a compound into simpler compounds or elements.
Decomposition
This type of reaction is one where a more active element takes the place of another element in a compound.
Single replacement or substitution.
Two reactants exchange ions to form a new compound. When the reactants are acids and bases, the process is termed neutralization reaction.
Double replacement.
A specific type of reaction (which can sometimes also fall under the categories given above) where oxygen reacts with a combustible reactant, usually hydrocarbons, to produce carbon dioxide, water, and a huge amount of energy.
Combustion reaction
Studied the behavior of gases in a systematical and quantitative manner.
Robert Boyle
Studied the relationship of temperature and volume of gases.
Jacques Charles
What is the R?
0.08206 L∙atm/mol∙K
What is m?
Mass (g)
What is MM?
Molar mass (g/mol)
Molar weight of unknown mass formula?
MM=mRT/PV
What are the homogenous mixture?
Solution, Colloids, and Suspension Solutions
Are stable mixtures with a very large surface area and solute particles ranging from 1 to 1000 nm.
Colloids
Its ability to scatter light when viewed at a right angle.
Tyndall effect
Colloidal systems composed of immiscible or partially miscible liquids .
Emulsions
Are unstable mixture of particles larger than 1000 nm, separating into phases.
Suspensions
A pure substance has a standard boiling point freezing point and vapor pressure, which may alter in the presence of soluble compounds.
Colligative properties of solution
Is inversely proportional to the vapor pressure, which means that a decrease (¯) in vapor pressure will result in the rise/increase (+) of boiling point of a liquid.
Boiling point
Function of the number of particles in solution and the presence of solute lowers the freezing point of pure solvent.
Freezing point
Pressure that needs to be applied to prevent the flow of pure solvent through a semi-permeable membrane into a solution.
Osmotic pressure
Constants for water (K) kb
Molal boiling
point elevation = 0.52°C kf
Molal freezing
point depression
1.86 C
