1030 Final exam 2024/2025 with 100% correct
answers
1). Filtration
Ans: Separates solid substances from liquids and solutions; based on a difference in
size.
2). Distillation
Ans: Separates a homogeneous mixture based on differences in boiling points.
3). Chromatography (paper)
Ans: Separates substances on the basis of differences in solubility in a solvent.
4). Intensive properties
Ans: Independent of the amount of substance present.
-Density, boiling point
5). Extensive properties
Ans: Dependent on the amount of substance present.
-Mass, volume.
6). Atomic number and mass number
Ans:
7). Isotopes
Ans: Atoms with identical atomic numbers but different mass numbers
8). Mole

, Ans: : the amount of a substance that contains as many elementary entities as there
are atoms in exactly 12 g C-12
9). Avogadro's number (na)
Ans: 6.0221418 x10^23
10). Electrostatic energy
Ans: potential energy that results from the interaction of charged particle
11). Quantized energy (max planck)
Ans: Energy can be absorbed or released from atoms only in certain amounts (quanta).
12). Heisenberg's uncertainty principle
Ans: the more precisely the momentum (mu) of a particle is known, the less precisely
its position (x) is known
13). Principal quantum number (n)
Ans: designates size of the orbital (shell)
-n values are integers >0
14). Angular momentum quantum number (l)
Ans: describes the shape of the orbital (subshells)
-l values are integers ranging from 0 to n − 1 for each value of n
15). Magnetic quantum number (ml)
Ans: specifies the three-dimensional orientation of the orbital
-Values are integers ranging from -l ...0 .... l
16). Electron spin quantum number (ms)
Ans: The "spin" of an electron describes its magnetic field, which affects its energy.
-Allowed values: +1/2 and −1/2.
