Abstract Molar volume is the volume that one mole of gas occupies when temperature and pressure are kept constant. The molar volume of a gas can be determined through evaluating how much gas is given off when the number of moles of the substance is known. To find the volume of gas that will be used to calculate the molar volume‚ the process of water displacement can be used. Reference Citation Cesa‚ J. (2002).

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

Hydrogen Selenide is toxic. It is made up of selenium which is also toxic‚ and hydrogen which is nontoxic. This substance is also colorless like hydrogen‚ but not like selenium which is a deep red color. There are reports of mine workers being poisoned by hydrogen selenide and selenium. Increasing industrial applications of selenium and the fact that workers may be exposed to Hydrogen Selenide have led authors to make a further investigation of the toxicity of this substance. The purpose of this
