by road vehicles. The second is hydrogen‚ the idea of using hydrogen‚ which is of course a gas and ambient conditions‚ came from the time when nuclear fusion was supposed to produce abundant electricity at very low cost‚ which could then be used to electrolyse water‚ yielding abundant and she cheap hydrogen. Unfortunately nuclear fusion has persisted in remaining on the horizon as a possible energy sources‚ and hence other strategies for generating hydrogen have been extensively investigated

solids. Structure: The simplest saturated acyclic hydrocarbon is methane‚ CH4. The other hydrocarbons belonging to this class can be taken as descendents of methane‚ resulted from the substitution of one or more atoms of hydrogen with hydrocarbon radicals. Therefore‚ if one hydrogen atom from methane is replaced by a methyl radical‚ -CH3‚ the hydrocarbon (superior to methane) will have the composition C2H6‚ named ethane. The alkanes can be: with a continuous chain‚ if all the carbon atoms are bound

Inside the living body‚ implanted metals are primarily exposed to highly oxygenated body fluids containing inorganic ions (chloride‚ carbonate‚ calcium‚ etc.)‚ proteins‚ lipids‚ amino acids and cells that assemble around the implanted metal [1]. Biomaterials devices made of smart metals such as the equiatomic binary alloy‚ nickel-titanium (commonly known as nitinol)‚ may corrode

1. Describe the nuclear fusion reaction that occurs in stars. Page 294 Stars are made primarily of the almond hydrogen the most common material universe. As a star forms‚ gravity pulls the hydrogen into a dense ball that heats up. Electrons are torn from the hydrogen and other atoms‚ creating a plasma made up primarily of protons (the nucleus of the hydrogen atom) and electrons. Normally‚ protons would repel each other. As matter accumulates ending the new star however‚ the protons move

started doing chemistry. Bubbles of hydrogen are formed‚ together with colourless solutions of beryllium or magnesium sulphate. For example: Calcium‚ strontium and barium Calcium sulphate is sparingly soluble‚ and you can think of strontium and barium sulphates as being insoluble. That means that you will get a layer of insoluble sulphate on all of these which will slow down the reaction or stop it entirely. In the calcium case‚ you will get some hydrogen produced together with a white

Purpose: The Purpose of this lab is to utilize‚ demonstrate and understand the various techniques and procedures used to gravimetric labs. For this particular lab we will utilize our scientific knowledge of related to gravimetric procedures to find the chloride content in an unknown soluble salt. Theory: Using our developed knowledge of the conservation of mass‚ solubility and precipitation it is possible (with some degree of error) to know the content of chlorine in a particular salt by dissolving it

and you tend to get carbon and hydrogen fluoride produced. It is of no particular interest. For example: The reaction between alkanes and iodine Iodine doesn’t react with the alkanes to any extent - at least‚ under normal lab conditions. The reactions between alkanes and chlorine or bromine There is no reaction in the dark. In the presence of a flame‚ the reactions are rather like the fluorine one - producing a mixture of carbon and the hydrogen halide. The violence of the reaction

Put all the potatoes into individual test tubes. 2. Pour 3mL of hydrogen peroxide into one test tube. Watch and time how much time goes by before the reaction begins. 3. Observe and write down the time. 4. Repeat steps 2 and 3 until all the potatoes have been tested and observed. Data: Type of potato Amount of hydrogen peroxide

measuring the total hydrogen yield of the reaction. Stoichiometry was then used to find a molar ratio between hydrogen and zinc. After calculating the moles of zinc‚ the mass can then be figured by multiplying by the molar mass of zinc. Experimental Procedure. First an apparatus needed to be set up to measure the hydrogen gas given off in the reaction of the zinc on the nail and the hydrochloric acid. A Erlenmeyer flask was used to hold the acid and nail which released the hydrogen into a rubber
