old when the super force decays into the separate force of nature. Roughly 3 minutes after the big bang‚ the temperature of the universe have dropped to 1 billion degrees Fahrenheit‚ cool enough for atomic nuclei to form. The element hydrogen forms and some hydrogen atoms fuse to create heliums. During the fourth minute of the big bang‚ reactions took place that locked up the remaining neutrons in helium nuclei. By just over 30 minutes after the big bang‚ all of the positrons (anti-matter) had

Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

was to make a vertical axis wind turbine (VAWT) that instead of charging a battery‚ would deliver its power directly to an electrolysis apparatus to make hydrogen and oxygen gas. The reason for doing this would be to avoid the complications and expenses of inverters‚ batteries‚ and connecting the turbine to the grid. It would also make hydrogen gas which could power a car‚ a generator‚ or be used as a welding/cutting torch‚ which is what I intended to use it for. That was the idea‚ however I

between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms share the electrons. Combination of silicon and oxygen - The combination of silicon and oxygen is similarly to carbon and hydrogen‚ silicon and oxygen form numerous compounds. They are commonly known as silicates An Example - Beach sand is a good example

If you heat hydrogen to 10 million degrees‚ it creates energy that stars use to shine. When hydrogen is heated to 10 million degrees‚ a process called nuclear fusion takes place. It creates a new‚ heavier element called helium. Some of the matter in this reaction is covered to pure energy which bursts out

of a lot of energy. Stars are powered by nuclear fusion in their cores‚ mostly converting hydrogen into helium (Fusion in Stars‚ 2012). The production of new elements by nuclear reactions is called nucleosynthesis. A star ’s mass determines what type of nucleosynthesis occurs during explosive changes in its life cycles (Fusion in Stars‚ 2012). Nuclear Reactions The smallest stars only convert hydrogen into helium. Medium stars‚ such as our Sun‚ can convert helium into oxygen and carbon.
