There are 2 worksheets (and answers) as well as notes and worked examples (ws2). WS1 has 2 pages of questions where the student has to choose whether a reaction is either endothermic or exothermic, draw and label an energy profile. There are also some simple calculations to determine the amount of energy given off from a known mass of an organic compound. WS2 contains notes, worked examples and 10 problems (and answers) focused on the equation Using q = mCΔT and Hess's law. The problems will be useful for students enrolled in Honors, AP or those who would like to sit the National Chemistry Olympiad competition. The problems are of straight forward to moderate difficulty. Key words: Hess's law, thermochemistry, enthalpy, heat, thermodynamics, calculations.

This resource will be useful for teachers new to the profession or those with limited experience teaching chemistry. It contains * notes for the teacher including a 4-6 period lesson plan and template for practicals (5 pages in total); * a simple power point presentation with 13 slides that gives step by step instructions on how to balance equations. Reactions are limited to group 1 and 2 metals and their associated oxides, hydroxides and carbonates; * 4 worksheets (and answers) for word, symbol, and also word and symbol problems. The worksheets (and answers) can be found as separate resources if notes and lesson plans are not required.

This test comprises about 45 marks worth of short answer questions (4 pages long). The focus is on the periodic table, electron configuration, balancing simple word and symbol, equations, universal indicator colors and a few questions concerning the electrolysis of NaCl. Answers are included.

This resource contains two fun-worders based around the first 20 elements of the periodic table. In the first fun-worder, the student has to find the element. Each element succeeds its atomic number (find the name and you find the atomic number). The 2nd fun-worder has both the proton number (before the word) and the atomic mass (after the word). The student then fills in the periodic table grid (supplied) in the correct order. The students love these activities and it can take a good 45 minutes to complete. It is fun and builds familiarity with the PT. Other shorter activities are included: match symbols and names, and electron configuration practice.

This test is about 1 hours long. It includes questions about calculating oxidation number, observations and balancing half and full REDOX equations. This test would be useful for students doing AP or Honors chemistry. Answers are included.

There are two worksheets (with worked answers) in this resource. WS1 focuses on word equations and limits reaction to those of oxides, hydroxides and carbonates. Notes are also provided. The intention is for students to get used to the idea of always writing down the salt and that water is the other product. WS2 asks students to balance the symbol equations. The equations are limited to acids reacting with oxides, carbonates and hydroxides. Both worksheets are also part of a larger resource called "Chemistry: balancing equations involving metals and their salts". This resource will suit students learning about balancing equations for the first time.

This resource consists of notes and worked examples to show how to establish a molecule's Lewis structure and molecular shape. The problems are more difficult than ws1 and would suit students who are doing Honors, AP or are interested in competing in the National Chemistry Olympiad competition.

This resource has a set of notes with worked examples to explain how to determine Lewis structures, molecular shapes and formal charges. The accompanying worksheet uses these skills to predict shapes and reason the bond angles. Some problems are based on the comparison of two molecules.

This resource consists of 2 worksheets: 25 calculation problems (and worked answers) involving aspects of acid base chemistry and some general pH calculation notes, which initially cover simple calculations. . The first half of each work sheet covers pH calculations in both acid and base conditions and calculation of H+ and OH- ion concentrations. The 2nd side of the worksheets focus on pH calculations involving partial neutralisation reactions where the student has to work out what species is in excess before calculating the pH. Some problems also involve the use of n=m/M equation. These problems would suit students interested in Honors, AP or wanting to enter the National chemistry Olympiad competition.

This resource consists of some general REDOX notes, which outline how to balance REDOX equations and 2 double sided worksheets (and answers). The exercises include oxidation number elucidation, balancing half equations and balancing full equations. This resource would suit students who want to progress in the Honors program.

This resource consists of some general REDOX notes and 1 work sheet with 6 hard-to-difficult REDOX reactions to balance. The difficulty is due to the fact the students must first convert word equations into symbols. One problem requires them to balance under alkaline conditions and the metal product is not immediately obvious. The problems introduce the students to uncommon reactions where the acid itself is converted to products other than hydrogen gas. This worksheet would be suitable for students doing AP, Honors or wanting to take part in the National Chemistry Olympiad competition.

This resource contains 2 worksheets (4 pages) of crystallisation problems (and answers). The exercises would be suitable for students wanting to do Honors or AP.

This worksheet (and answers) contains 8 empirical formula problems. It would suit students wanting to do Honors or AP. Key words: calculations, molecular formula, empirical formula,

This resource consists of 4 work sheets and answers. It would suit students aged 14-16 learning to balance word and symbol equations. WS1 contains 20 word and symbol equations involving the reaction of metals with oxygen, chlorine, water or an acid. WS2 contains 20 word and symbol equations involving reactions between metal salts (carbonates, hydroxides and oxides) and acids WS3 requires the students to complete acid base word and symbol equations WS4 requires symbol equations for reactions with metals. Some of these resources appear elsewhere.
