Chemistry flashcards for Allied Health Sciences Entry Test
21 of 66 cards from the Chemistry deck — real questions with worked answers.
Define one mole and state Avogadro's number.
One mole is the amount of substance containing as many elementary entities as there are atoms in 12 g of carbon-12. Avogadro's number = 6.022 x 10^23 particles per mole.
How is the average atomic mass of an element calculated from its isotopes?
Average atomic mass = sum of (fractional abundance x isotopic mass) for all isotopes. It is a weighted average of the masses of all naturally occurring isotopes.
Write the formula relating number of moles to mass and molar mass.
Number of moles (n) = given mass (m) / molar mass (M).
How do you find the number of particles given the number of moles?
Number of particles = number of moles x Avogadro's number (6.022 x 10^23).
What is the molar volume of an ideal gas at STP?
22.414 dm^3 (litres) per mole at STP (0 degrees C / 273.15 K and 1 atm).
Distinguish between empirical formula and molecular formula.
Empirical formula gives the simplest whole-number ratio of atoms of each element; molecular formula gives the actual number of atoms of each element in a molecule. Molecular formula = n x empirical formula.
Outline the steps to determine an empirical formula from percentage composition.
1) Assume 100 g so percentages become grams. 2) Divide each element's mass by its atomic mass to get moles. 3) Divide all mole values by the smallest. 4) Convert ratios to whole numbers to get the empirical formula.
How is the molecular formula obtained from the empirical formula and molar mass?
Find n = molar mass / empirical formula mass, then multiply each subscript in the empirical formula by n.
The empirical formula of a compound is CH2 and its molar mass is 42 g/mol. What is its molecular formula?
Empirical mass of CH2 = 14; n = 42/14 = 3; molecular formula = C3H6.
What is stoichiometry?
Stoichiometry is the quantitative study of the relationships (mass, moles, volume) between reactants and products in a balanced chemical equation.
What does the coefficient ratio in a balanced equation represent?
The mole ratio (and for gases, the volume ratio) in which reactants combine and products form.
State the three types of stoichiometric relationships derivable from a balanced equation.
Mass-mass, mole-mole, and mass-volume (or volume-volume for gases) relationships between reactants and products.
Define limiting reactant.
The limiting reactant is the reactant that is completely consumed first and therefore determines (limits) the maximum amount of product that can be formed.
How do you identify the limiting reactant in a reaction?
Convert each reactant's amount to moles, divide by its coefficient in the balanced equation; the reactant with the smallest resulting value is the limiting reactant.
Define theoretical yield, actual yield, and percentage yield.
Theoretical yield = maximum product calculated from stoichiometry. Actual yield = product actually obtained experimentally. Percentage yield = (actual yield / theoretical yield) x 100.
Why is actual yield usually less than theoretical yield?
Due to side reactions, incomplete reactions, loss during transfer/purification, reversible reactions, and impure reactants.
What is filtration and what does it separate?
Filtration separates an insoluble solid (residue) from a liquid (filtrate) by passing the mixture through a porous filter medium such as filter paper.
What is crystallization and on what principle is it based?
Crystallization is purifying a solid by dissolving it in a hot solvent, then cooling so pure crystals form. It is based on the difference in solubility of a substance at high and low temperatures.
Why must a solution be saturated and hot before crystallization, then cooled slowly?
A hot saturated solution holds maximum solute; slow cooling reduces solubility gradually, allowing pure, well-formed crystals to separate while impurities stay in the mother liquor.
Define sublimation and give an example of a substance that sublimes.
Sublimation is the direct conversion of a solid to vapour (and back to solid) without passing through the liquid state. Examples: iodine, naphthalene, ammonium chloride, dry ice (solid CO2).
What is solvent extraction and the principle behind it?
Solvent extraction separates a solute from one solvent using another immiscible solvent in which the solute is more soluble. It is based on the distribution (partition) of a solute between two immiscible liquids.
Planning Chemistry for Allied Health Sciences Entry Test
Chemistry is about 30% of the Allied Health Sciences Entry Test syllabus by topic count — 45 of 152 topics, spread over 12 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 Organic Chemistry and Biochemistry (5 topics), Basic Concepts of Chemistry (4 topics), Gases (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.
