Overview[ edit ] To summarize the properties and behaviors of acids and bases, this chapter lists and explains the various chemical reactions that they undergo. You may wish to review chemical equations and types of reactions before attempting this chapter. The following reactions are net ionic equations. In other words, spectator ions are not written.
I know from feedback that my gcse science summary revision pages have proved useful but they do not guarantee a high grade, that all depends on you and the factors mentioned in point 4. Please note that my GCSE science revision pages are designed to be used for online convenience, so, beware, printouts could be quite long!
Some quizzes, particularly the compilations, are quite large and take some time to download. Links to specific GCSE chemistry notes and quizzes about the topic in question have been added, and from these pages, you may find other links to more useful material linked to the topic.
In terms of old grades the following is an approximate comparison: Elements, compounds and mixtures: Predicting and identifying reactions and products: Monitoring and controlling chemical reactions: It is concerned with the synthesis, formulation, analysis and characteristic properties of substances and materials of all kinds.

You should appreciate the achievements of chemistry in showing how the complex and diverse phenomena of both the natural and man-made worlds can be described in terms of a small number of key ideas which are of universal application, and which can be illustrated in the separate topics set out below.Year 8 Module 1 Chemical Reactions the reactions of acids and alkalis – know this is a neutralisation equation Write a word equation for complete combustion and list condition for the reaction to occur.
Describe how classroom fractional distillation works. 1. Magnesium metal is an active metal. Magnesium will react with hydrochloric acid.
2. Illustration of a single displacement reaction.
Illustration of an oxidation-reduction reaction. Illustration of a reaction that produces a gas. 3. Write a balanced chemical equation and a net ionic equation.
The word "neutralization" is used because the acid and base properties of H + and OH-are destroyed or neutralized.
In the reaction, H + and OH-combine to form HOH or H 2 O or water molecules. A neutralization is a type of double replacement reaction. This chemical equation balancer can help you to balance an unbalanced equation. This balancer can also help you check whether the equation is balanced or not, thus you may edit the equation and check it's balance.
The balancer is case sensitive. Following are some equation input format examples: 1. H2 + O2 = H2O 2.
2H2 + O2 = 2H2O 3. Write the word equations for the observed chemical reaction 13 Chapter 2 - Acids, Bases and Salts Formative Assessment Manual for Teachers Write symbols and formulae for the reactants and products Balance the chemical equation for the observed reaction.
Derive a general equation . The equation showing the standard enthalpy change of formation for water is: you must end up with 1 mole of the compound. If that needs you to write fractions on the left-hand side of the equation, that is OK.
(In fact, Enthalpy of combustion equations will often contain fractions, because you must start with only 1 mole of whatever you.
