affecting the catalytic decomposition of Hydrogen peroxide Please refer to the additional files for tables/graphs. Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide. I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide. Introduction- The decomposition of Hydrogen peroxide is a process by which Hydrogen peroxide decomposes into water and Oxygen

the R Lab 1. One mole of hydrogen gas has a mass of 2.02 g. Use your value of molar volume to calculate the mass of one Liter of hydrogen gas at STP. The density is in g/L. Compare your value to a literature value? (Consult a hand book or text book) 2. In setting up this experiment‚ a student noticed that a bubble of air leaked into the gas tube when it was inverted in the water bath. What effect would this have on the measured volume of hydrogen gas? Would the calculate value

goggles and an apron or lab coat to protect our eyes and clothes. As we are using enzymes and Hydrogen Peroxide we need to be extra careful‚ ensuring they don’t come into contact with our eyes‚ skin or clothes. Catalyse is an enzyme found in all living cells. It makes Hydrogen Peroxide decompose into water and Oxygen. We will be measuring the amount of Oxygen released from the Hydrogen Peroxide. In order to do this we will use a measuring cylinder. This piece of apparatus measures

Chemist from the University of Glasgow in Scotland have taken a step closer towards producing clean hydrogen fuel in a maintainable way. Hydrogen gas is able to be burned to generate electricity without producing lethal releases‚ unlike fossil fuels. It is produced from water releasing them as gas‚ through a process called electrolysis‚ which uses electricity to break the bonds between hydrogen and oxygen. This technique is 30 times faster than the current method‚ and can be powered by renewable

Making and Testing for Hydrogen Gas Felicity Tyler Aim: To produce and test for hydrogen gas. Materials: * rubber stopper * dilute hydrochloric acid (HCI) * zinc pieces (Zn) * test-tube rack * matches * dilute sulphuric acid (H2SO4) * 2 cm strips of magnesium ribbon (Mg) * Iron pieces (Fe) * Test-tube Method 1. Test the different metals with the acids by separately combining

calcium carbonate content?Calcium carbonate is a substance found in the eggshells giving them hardness and strength. It is essential to the commercial egg industry that the biggest possible amount of eggs reaches the market. Hence‚ as calcium carbonate reacts steadily with hydrochloric acid to produce carbon dioxide as well as two other substances‚ I investigated which type of an eggshell contains more calcium carbonate. This reaction cannot be used directly to titrate the calcium carbonate because

hydrogen chloride has properties: Hydrogen chloride has one molecule of hydrogen and one molecule of chlorine: Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because

Hydrogen‚ interpreted from Greek as the water-creator (RSC site). Fundamentally it is by far the simplest element‚ yet it composes virtually all of the visible universe. Hydrogen is not merely omnipresent; in actuality‚ it is the oldest and arguably the most essential corporeality to the creation and sustainability of utterly all in existence. The aforementioned characteristic that hydrogen is immensely crucial to the survival of all lifeforms is supported by the fact that it is the building block

Chemistry – Titration experiment I – Standard Solution Prep Preparation of a standard solution of sodium carbonate Anhydrous sodium carbonate is a suitable chemical (primary standard) for the preparation of a standard solution. Standard Solutions are critical in chemistry because you need to have solutions with an EXACT known concentration and volume. Chemicals/Materials: solid sodium carbonate (Na2CO3) distilled water Apparatus: 250cm3 volumetric flask 250cm3 beaker Glass stirring

OF CATALASE ON HYDROGEN PEROXIDE The aim of the experiments is to see if increasing the surface area of the enzyme Catalase‚ affects the relative activity of the substrate Hydrogen peroxide. Then to observe and measure the effect the Catalase has on the chemical breakdown of the hydrogen peroxide. My theory is if you keep increasing the surface area of Catalase‚ the more active sites are available to join with the substrate causing an increase in the breakdown of the hydrogen peroxide producing
