Learning Outcomes for Chemical Reactions and Reaction Rates Revision from S1 and S2 Ways of identifying if a chemical reaction has occurred. Examples of chemical reactions S3 Chemistry State why it’s important to know the rate of a chemical reaction Produce a line graph with correct scale, labels, plot and line Produce a bar graph with correct scale, labels and bars State 4 ways to increase the rate of a chemical reaction Describe the effect of particle size on the rate of a chemical reaction Describe the effect of temperature on reaction rate Predict the position and end point of reaction rate lines on a graph with varying temperature State the definition of a catalyst Describe the properties of a catalyst Predict the appearance of graphs in reactions carried out with and without a catalyst and predict the end point positions of such reactions on these graphs Predict the position and end point of reaction rate lines on a graph with varying factors Explain the trends shown in reaction rate graphs I can use a line graph to determine the average rate at different time intervals State the definition of an exothermic reaction State the definition of an endothermic reaction Learning Outcomes for Atomic Theory and Periodic Table S3 Chemistry Identify the 3 sub atomic particles in an atom State the location, charge and mass of each sub atomic particle Calculate the number of protons, neutrons and electrons in an atom Identify whether a species has an equal or unequal number of protons and electrons and use this to state whether it is an atom or ion. State the charge of an ion. Calculate the charge on a ion using nuclide notation Use the periodic table to identify whether an element is a metal or non-metal State that elements are listed in the periodic table in order of increasing atomic number State that some groups contain elements with similar chemical properties State the definition of an isotope Appreciate the varying stability and practical application of isotopes Describe the relationship between relative atomic mass and isotopes State what a diatomic element is State the 7 diatomic elements using the periodic table Learning Outcomes for Bonding and Properties S3 Chemistry Describe and carry out a test to find out if a substance conducts electricity Predict the type bonding present from the formulae of an ionic compound Describe how an ionic bond forms Describe the properties of an ionic compound Predict the type bonding present from the formulae of a covalent compound Describe how a covalent bond forms Describe the properties of a covalent compound Explain why noble gases are unreactive State that electrons are found in orbitals of differing shape Predict the bond order by the number of shared pairs of electrons State whether covalent substances form discrete molecular or giant network structures Predict the typical properties of discrete molecular and giant network covalent structures State that ionic substances form giant lattices of oppositely charged ions and predict the typical properties of ionic substances Explain why ionic substances conduct when molten or in solution and do not conduct when solid Use my understanding of lone pairs of electrons to predict the molecular shape Learning Outcomes for Acids and Alkalis Revision from S2 The pH scale; which colours and numbers represent an acid, an alkali and neutral substances. The names and formula of common lab acids. Examples of acids and alkalis you would find in everyday life. S3 Chemistry 1. A base is any substance which will neutralise an acid. 2. The effect of soluble non-metal oxides on the pH of water. 3. The environmental impact of non-metal oxides dissolving in rain water. 4. The effect of soluble metal oxides on the pH of water. 5. The effect of insoluble oxides on the pH of water. 6. Uses of acids in food and drink and their impact on health. 7. Acids contain aqueous hydrogen ions, H+(aq). 8. Dissociation of water into hydrogen and hydroxide ions. 9. pH is related to the concentration of hydrogen and hydroxide ions in pure water, acids and alkalis. 10. Acids are corrosive and can breakdown and damage certain rocks, metals and organic matter. 11. Neutralisation is a reaction that decreases the hydrogen ion concentration. 12. Metal hydroxides, metal oxides and metal carbonates are all bases that can neutralise an acid. 13. A salt is formed whenever an acid is neutralised. 14. A titration is used to find the unknown concentration of an acid or an alkali. 15. By identifying spectator ions and removing (omitting) them from a reaction equation, you can state what the reacting ions are. Learning Outcomes for Chemical Formula, Mass and The Mole S3 Chemistry Use the endings –ide, -ite and –ate to show the elements present in compounds Use the compound name to state the elements present in the compound. Write chemical formulae using valency State that atoms of different elements have different masses Calculate gfm from chemical formulae using RAM numbers Write a word equation and convert it into a formulae equation Balance chemical equations Use n=m/GFM in calculations S4 Chemistry Describe the difference between a covalent formula and an ionic formula Write ionic formulae Calculate the percentage, by mass, of an element Use balanced equations to calculate unknown masses. Use balanced equations to calculate unknown concentrations and volumes
