Temp. 25 C Pressure 76.0 Indirect Measurement of Volume INTRODUCTION: The purpose of this lab was to demonstrate an indirect measurement of volume. This was done by determining the volume of a single drop of using a graduated cylinder to measure a known amount of consistent drops‚ which allows for the individual volume to be determined mathematically. MATERIALS AND METHODS: Pipette‚ 10ml graduated cylinder‚ water‚ rubbing alcohol and hand soap. A pipette was used to place

Hydrogen peroxide and iodide ions Aim: To determine the rate equation for the reaction between Hydrogen peroxide and iodide ions‚ and to investigate the effects of a catalyst and temperatures on the reaction and to derive the activation enthalpy. Background knowledge: 1Hydrogen peroxide reacts with iodide ions producing iodine‚ when in an aqueous acid solution. H2O2 (aq) + 2I- (aq) + 2H3O+(aq) I2 (aq) + 2H2O(l) To detect iodine you can look at the color shown by the addition of starch

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

Electricity from Natural Gas Natural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants and animals originally obtained from the sun is stored in the form of carbon in natural gas. Natural gas is combusted to generate electricity‚ enabling this stored energy to be transformed into usable power. Natural gas is a nonrenewable resource because it cannot be replenished on a human time frame

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

Chemistry 121 Experiment 19 Molar Mass Determination y Depression of the Freezing Point Introduction: The most commonly used liquid is water. In this experiment we study the equilibria that can exist between pure water and an aqueous solution‚ and ice‚ the solid form of water. The heat will transfer from a higher temperature to a lower temperature. In order for water to change states of matter‚ it takes a certain amount of kinetic energy or heat. The shift from ice to water (solid to a liquid)

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

they weigh the same. What is this difference? The relationship between the lead and feathers is expressed by the physical property called density. Density is defined as the ratio of a substance’s mass to the volume it occupies. Density (g/mL) = Mass (g)___ Volume (mL) In this laboratory exercise‚ you will be using skills and techniques learned earlier to determine the identity of different substances. To determine the precision of your technique‚ you will calculate the
