EXPERIMENT 1: Aim: To range the metals copper‚ lead‚ silver and zinc together with hydrogen. Start with the strongest reducing agent. Hypothesis: The nobler a metal is‚ the worse reducing agent. Apparatus/requirements: Sandpaper‚ strips of; zinc‚ lead‚ silver and copper‚ solutions containing aqueous; Zn2+‚ Pb2+‚ Cu2+ and Ag+ ions (0.2 M)‚ hydrochloric acid (5.0 M)‚ emery paper‚ test-tubes. Method: Burnish the three metal strips to get a shiny surface‚ after drop a drop of each of the metal

metal: Acids give hydrogen gas along with respective salt when they react with a metal. Example:- Hydrogen gas and zinc chloride are formed when hydrochloric acid reacts with zinc metal. Hydrogen gas and sodium chloride are formed when hydrochloric acid reacts with sodium metal. Hydrogen gas and iron chloride are formed when hydrochloric acid reacts with iron. Hydrogen gas and zinc sulphate are formed when zinc metal reacts with sulphuric acid Test for hydrogen gas: The gas evolved

following chemical reactions. (i) Hydrogen + Chlorine → Hydrogen chloride (ii) Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride (iii) Sodium + Water → Sodium hydroxide + Hydrogen Answer (i) (ii) (iii) Question 3: Write a balanced chemical equation with state symbols for the following reactions. (i) Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride. (ii) Sodium hydroxide solution (in water)

between sodium thiosulphate (thio) and hydrochloric acid. Hydrochloric Acid + Sodium Thiosulphate "" sodium chloride + water + sulphur The reactants are both colourless‚ but one of the products‚ sulphur‚ is yellow‚ so we can use this fact to follow the rates of reaction. I am going to investigate how the concentration of the acid effects the speed of the reaction.

The Earth’s atmosphere has changed over billions of years‚ but for the past 200 million years it has been much as it is today. We are‚ however‚ causing our atmosphere to change by human activity. Burning fossil fuels and deforestation are two examples of human effect on the environment. Composition of the Earth’s atmosphere The composition of air You need to know the proportions of the main gases in the atmosphere. The Earth’s atmosphere has remained much the same for the past 200 million years

substances is called chemical equation. Example: In this equation‚ A and B are called reactants and C and D are called the products. Arrow shows the direction of chemical reaction. Condition‚ if any‚ is written generally above the arrow. When hydrogen reacts with oxygen‚ it gives water. This reaction can be represented by following chemical equation. In first equation words are used and in second symbols of substances are used to write the chemical equation. For convenience‚ symbol of substance
