CORRECT ANSWERS GRADED A+
◍ Exam Duration.
Answer: Total time allocated for completing the exam.
◍ Merged Question Paper.
Answer: Combined set of questions from various topics.
◍ How do group 7 elements achieve full outer shells?.
Answer: Group 7 elements need 1 electron to fill their outer shell so they
just share an electron with another group 7 element, this is known as
covalent bonding

element have?.
Answer: When a group 7 element reacts with a metal the group 7 element
gains and electron and forms a 1- ion
◍ Chemistry 8462/1H.
Answer: Specific code for AQA Chemistry exam.
◍ State the four different ways of separating mixtures.
Answer: Four different ways of separating mixtures are filtration,
crystallisation, distillation or chromatography
◍ What are the properties of ionic compounds.
Answer: The properties of ionic compounds are that they can transfer
, electrons when they react, they have high melting and boiling points and can
conduct electricity when they are not solids
◍ Relative formula mass (Mr).
Answer: The sum of the atomic masses of all the atoms in a formula
◍ Where are elements shown?.
Answer: Elements are shown in the Periodic table
◍ Document Sharing.
Answer: Process of distributing documents electronically.
◍ Mark Scheme.
Answer: Guidelines for grading exam responses.
◍ Higher Tier.
Answer: Advanced level of assessment for students.
◍ Assessment Objectives.
Answer: Criteria for evaluating student performance.
◍ Stoichiometry.
Answer: Study of quantitative relationships in chemical reactions.
◍ Question Types.
Answer: Different formats of questions in the exam.
◍ Does graphite have a high or low melting and boiling point?.
Answer: Graphite has a high melting and boiling point
◍ What is formed when hydrochloric acid reacts with magnesium?.
Answer: Hydrochloric Acid + Magnesium → Magnesium Chloride +
Hydrogen
◍ What is the word equation for the reaction between an acid and a metal?.
Answer: Acid + Metal → Salt + Hydrogen
◍ Downloaded by.
Answer: Indicates who accessed the document.
,◍ AQA.
Answer: Assessment and Qualifications Alliance, UK exam board.
◍ Exam Format.
Answer: Structure and layout of the examination paper.
◍ Alkali.
Answer: When dissolved in water, it produces OH⁻ ions. Its solution has a
pH > 7.
◍ What is the Relative Atomic Mass (Ar)?.
Answer: Relative Atomic Mass is the final mass that takes in consideration
all the isotopes of an element
◍ Safety Procedures.
Answer: Guidelines to ensure safety in the lab.
◍ Chemical Equations.
Answer: Representations of chemical reactions using symbols.
◍ How many elements are there?.
Answer: There are around 118 elements
◍ Is making bonds exothermic or endothermic?.
Answer: Making bonds releases energy so it is exothermic
◍ Periodic Table.
Answer: Chart organizing all known chemical elements.
◍ University of Nairobi.
Answer: Institution mentioned in the context of notes.
◍ Subject Content.
Answer: Topics covered in the Chemistry curriculum.
◍ Why can't the atom economy be over 100%?.
Answer: The atom economy can't be over 100% because that would mean
we're creating atoms which is impossible
◍ 57 pages.
, Answer: Total number of pages in the document.
◍ Where are transition metals located?.
Answer: Transition metals are located in the centre of the periodic table
◍ Practical Experiments.
Answer: Hands-on activities to demonstrate chemical principles.
◍ Element.
Answer: A substance made up of only one type of atom. Cannot be broken
down chemically into any simpler substance
◍ Describe the structure of a metal.
Answer: Metals consist of a giant structure of atoms arranged in regular
layers, the electrons in the outer energy level of each atom are delocalised
◍ Neutral.
Answer: A solution with a pH value of 7 which is neither acidic nor alkaline.
Or, something that has no electrical charge
◍ Paper 1.
Answer: First exam paper in the AQA Chemistry series.
◍ GCSE.
Answer: General Certificate of Secondary Education, UK qualification.
◍ Student Notes.
Answer: Personalized study materials created by a student.
◍ Revision Strategies.
Answer: Methods to prepare effectively for exams.
◍ How do we balance equations using moles?.
Answer: To balance an equation using moles we need to calculate the
number of moles of all the chemicals then put the number of moles in front
of the chemical the divide all the numbers with smallest number, the
equation is now balanced
◍ What is a molecule?.
