PAPER 2026 QUESTIONS WITH ANSWERS
GRADED A+
◍ molar gas volume.
Answer: 24 dm³ at r.t.p.
◍ Describe the structure of Graphite.
Answer: Graphite has a giant covalent molecular structure it contains many
layers of carbon atoms each carbon atom covalently bonded to three other
carbon atoms, the layers are held by weak forces between them
◍ Is graphene a good or bad conductor of electricity?.
Answer: Graphene is a good conductor of electricity
◍ How do you carry out a titration?.
Answer: Fill up a flask with 25cm³ of sodium hydroxide solution, then add 5
drops of indicator to the solution, then place the flask on a white tile so we
can see the colour change. Fill a burette with sulfuric acid. Slowly add the
acid into the alkali until it nuetralsises, read the volume, record the results
on the burette
◍ The higher the temperature, the more particles will have...
Answer: enough energy to react (the activation energy)
◍ ethanoic acid.
Answer: CH₃COOH, a weak acid, the main component of vinegar apart
from water
,◍ pH scale.
Answer: A measure of acidity or alkalinity of water soluble substances
◍ What are the forces of attraction between the negative delocalised electrons
and the positive ions?.
Answer: There are strong electrostatic forces of attraction between the
negative delocalised electrons and the positive ions
◍ electron transfer.
Answer: movement of electrons from one atom, ion or molecule to another
◍ HT What happens in gaseous reactions when the pressure of a system in
equilibrium is increased?.
Answer: The equilibrium position shifts towards the side with the smaller
number of molecules as shown by the symbol equation for the reaction
◍ limiting reactant.
Answer: The reactant that runs out first in the chemical reaction and limits
the amount of product created
◍ Ernest Rutherford.
Answer: British physicist (born in New Zealand) who discovered the atomic
nucleus and proposed a nuclear model of the atom (1871-1937)
◍ Ore.
Answer: Rock which contains enough metal to make it economically
worthwhile to extract.
◍ fractional distillation.
Answer: The separation of the components in a mixture of liquids having
different boiling points by vaporization.
◍ endothermic.
Answer: A reaction in which more energy is taken in than is released by the
formation of bonds.
◍ concentration.
Answer: A measure of how much solute is dissolved in a specific amount of
, solvent or solution. = Amount of solute (g)/Volume of solution (dm³)
◍ Does silicon dioxide have a high or low melting and boiling point?.
Answer: Silicon dioxide has a high melting and boiling point
◍ temperature.
Answer: A measure of the average kinetic energy of the particles in a sample
of matter.
◍ Can diamond conduct electricity?.
Answer: Diamond cannot conduct electricity
◍ atom economy.
Answer: (Molecular mass of the desired product / Sum of molecular masses
of all products) x 100
◍ Give an example of an electrolyte.
Answer: An example of an electrolyte is an ionic compound
◍ Give an example of an acid producing hydrogen ions.
Answer: HCl → H⁺ + Cl⁻
◍ Describe the correlation of the reactivity of a group 7 element and it's
location in the table.
Answer: Group 7 elements have a lower reactivity as you move down the
column
◍ What is formed when a metal reacts with oxygen?.
Answer: When a metal reacts with oxygen a metal oxide is formed
◍ What is the word equation for the reaction of a group 1 metal and water?.
Answer: Metal + Water → Metal Hydroxide + Hydrogen
◍ H₂.
Answer: Molecular hydrogen
◍ Describe the particles in a gas.
Answer: The particles in a gas are much further apart in a random
arrangement, they move very quickly
