Chemistry flashcards for NUMS Entry Test
21 of 51 cards from the Chemistry deck — real questions with worked answers.
State the law of conservation of mass.
Mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.
Differentiate between an atom, a molecule and an ion.
An atom is the smallest particle of an element that can take part in a chemical reaction. A molecule is two or more atoms chemically bonded together. An ion is an atom or group of atoms carrying a net electrical charge due to loss or gain of electrons.
Define relative atomic mass (Ar).
The average mass of the atoms of an element relative to 1/12 the mass of one atom of carbon-12. It has no units.
What is Avogadro's number and what does one mole represent?
Avogadro's number is 6.022 x 10^23. One mole is the amount of substance containing 6.022 x 10^23 particles (atoms, molecules or ions), equal in grams to the substance's molar mass.
Give the formula linking number of moles, mass and molar mass.
Number of moles (n) = mass (g) / molar mass (g/mol).
What volume does one mole of any ideal gas occupy at STP?
22.4 dm3 (22.4 liters) at standard temperature and pressure (0 C, 1 atm).
Define stoichiometry.
The study of quantitative relationships (mole, mass and volume ratios) between reactants and products in a balanced chemical equation.
What is a limiting reactant?
The reactant that is completely consumed first in a reaction, thereby determining the maximum amount of product that can be formed.
How is percentage yield calculated?
Percentage yield = (actual yield / theoretical yield) x 100.
Define empirical formula and molecular formula.
Empirical formula is the simplest whole-number ratio of atoms of each element in a compound. Molecular formula gives the actual number of atoms of each element in one molecule.
How is the molecular formula obtained from the empirical formula?
Molecular formula = (empirical formula) x n, where n = molar mass / empirical formula mass.
What are the relative charges and masses of the proton, neutron and electron?
Proton: charge +1, mass 1 amu. Neutron: charge 0, mass 1 amu. Electron: charge -1, mass approximately 1/1836 amu (negligible).
Define isotopes and give an example.
Isotopes are atoms of the same element with the same atomic number (protons) but different mass numbers (different numbers of neutrons). Example: carbon-12 and carbon-14.
What do the atomic number (Z) and mass number (A) of an atom represent?
Atomic number Z = number of protons (and electrons in a neutral atom). Mass number A = number of protons + number of neutrons.
Name the four quantum numbers and what each describes.
Principal (n) - energy level/size; Azimuthal (l) - subshell/shape; Magnetic (m) - orbital orientation; Spin (s) - direction of electron spin (+1/2 or -1/2).
What values of azimuthal quantum number (l) correspond to s, p, d and f subshells?
s = 0, p = 1, d = 2, f = 3.
How many orbitals and maximum electrons are in s, p, d and f subshells?
s: 1 orbital, 2 electrons; p: 3 orbitals, 6 electrons; d: 5 orbitals, 10 electrons; f: 7 orbitals, 14 electrons.
State the Aufbau principle.
Electrons fill orbitals starting from the lowest available energy level before filling higher ones.
State the Pauli exclusion principle.
No two electrons in an atom can have the same set of all four quantum numbers; an orbital holds a maximum of two electrons with opposite spins.
State Hund's rule.
Electrons occupy degenerate (equal-energy) orbitals singly with parallel spins before any orbital is doubly occupied.
Write the electronic configuration of chromium (Z=24) and explain its anomaly.
[Ar] 3d5 4s1. Chromium adopts this instead of 3d4 4s2 because a half-filled 3d subshell gives extra stability.
Planning Chemistry for NUMS Entry Test
Chemistry is about 30% of the NUMS Entry Test syllabus by topic count — 47 of 158 topics, spread over 15 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 35 hours.
The heaviest chapters are Fundamental Concepts of Chemistry (4 topics), Atomic Structure (4 topics), Chemical Bonding (4 topics) . Front-load those while your energy is high; the short chapters are better revision filler later.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
