(ii) Give an ionic equation to represent the neutralization reaction. Q2. Manganese (IV) oxide catalyses the decomposition of aqueous hydrogen peroxides. In an experiment 50.0 cm3 of aqueous hydrogen peroxide was mixed with 0.50 g of manganese (IV) oxide. The total volume of oxygen formed was measured every 10 seconds

fusion. Nuclear fusion is a reaction where matter is forced together and the nuclei are fused together. This is how the first start was born when hydrogen atoms were fussed together to create helium. After this many more starts and a lot more elements were created. Stars start there life as a cloud of gas called a nebula. Mainly consisting of hydrogen and helium. The gases will then be drawn to a centre point of gravity which will then create a protostar. And then the nuclear fusion in the core

Chapter 10 Practice Test: 1) How do you make a proton out of a hydrogen atom? E) remove an electron from a hydrogen atom 2) What is an acid? E) anything that donates hydrogen ions 3) What is a base? D) anything that accepts a hydrogen ion 4) What best describes what happens when an acid such as HCl is mixed with water? B) The proton chemically bonded to the chlorine is transferred to a water molecule and forms a chloride ion and a hydronium ion. 5) According to the following reaction‚ which

understand the SN1 and SN2 mechanism involved in the reaction 3. To determine the yield of percentage of t-butyl chloride II. Introduction An alkyl halide is a derivative of alkanes. Alkanes are hydrocarbons with a functional group C-C. The hydrogen atom is then replaced by a halogen (F‚ Cl‚ Br‚ I). Therefore‚ alkyl halides are compounds that have a halogen atom bonded to a saturated‚ sp3 hybridized carbon atom. These could be classified according to the number of alkyl groups attached to the

a cheap method to produce hydrogen. A method of industrial synthesis of hydrogen and oxygen through electrolysis was developed by Dmitry Lachinov in 1888. Electrolysis of water requires excess energy in the form of over potential to overcome barriers. Without the excess energy the electrolysis of water happens very slowly or not at all. Water has an electrical conductivity about one 1‚000‚000 of seawater. The Purpose of electrolysis is to separate water into Hydrogen and Oxygen gas. My hypothesis

wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion. C3H6O3----->C3H5O3++H- C2H3OHCOOH--------->C2H3OHCOO+ +H- Hydrogen ion is the acid in lactate acid‚ it interfere with electrical signals in muscles and nerves‚ slows energy reactions‚ and impairs muscle contraction. The burn up we feel in intense exercise is the cause of hydrogen ion. During this experiment(Muscle fatigue lab) it will be seen that after a while of squeezing a small

N‚N-Dimethylanaline to form the product both sodium carbonate and concentrated HCl was added to sulfanilic acid. The sodium carbonate accepts a hydrogen from sulfanilic acid a zwitterion therefore making it much more reactive later in the reaction. The concentrated HCl was used to form a nitrosonium ion from sodium nitrate. The oxygen attacks two hydrogen ions in solution and leaves as a water molecule. This process created the nitrosonium ion that reacts with the activated sulfanilic acid to create

Double Bond Position 4. Presence of Rings. Carbon skeletons can have double bonds in different locations and also different numbers of double bonds. 4.Hydrocarbons only have hydrogen and carbon molecules‚ hence the name. Hydrocarbons are hydrophobic because they mostly consist of hydrogen and carbon bonds
