Describe the motion of atoms and molecules in a gas. the atoms and molecules bounce off one another each time they come in contact with eachother. they never bond‚ but reflect off of eachother and spread around. 2. How are the behavior and arrangements of gas molecules similar to and different from soccer players

Oil and gas conservation means their better and more efficient use with regard to economic‚ social or environment costs and benefits resulting minimization of wastage and protection of environment. A very high priority is attached by the government to conservation of petroleum products in view of the need to reduce increasing gap between demand for and supply of oil and petroleum products. Government has initiated various steps to promote conservation of petroleum products in the different sectors

all having their own drawbacks. But‚ the one that will be focused upon in this analysis is hydrogen as a source of fuel‚ and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us‚ how it might hurt us‚ and whether it is worth pursuing from an ethical stance. Background: Hydrogen has already been under the micro scope for many years as an alternative fuel source to us

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

ENPE 573 – Unconventional Gas Exploitation Introduction to Shale Gas Classification‚ Formation‚ & Extraction Abstract The production of conventional gas has been declining over the last few years due to dwindling reserves. To counter-act this decline‚ companies are quickly turning to unconventional gas plays that can offer even greater reserves as shown in figure 1. Unfortunately‚ recovering unconventional gas is a very difficult process that requires advanced stimulation and/or

Calculation on the molar enthalpy change of a neutralization reaction Principle H2SO4(aq)+2NaOH(aq)=Na2SO4(aq)+2H2O(l) The reaction is a exothermic reaction‚ when the heat released by it is absorbed by water‚ the temperature of the water increases. The heat produced by the reaction can be calculated if it is assumed that all the heat is absorbed by the water. Heat change of reaction=-heat change of water =-mH2O×cH2O×△TH2O As the water has gained the heat produced by the reaction‚ the heat change

Aim To investigate the effect of molar mass on the molar heat of combustion of adjacent members of a homologous alcohol series. Introduction Chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance. The heat of reaction is determined by the difference in the enthalpy between the reactants and products. The molar heat of combustion of a substance is the quantity of heat liberated when one mole of that substance is burnt completely in air. In the case

When hydrogen gas comes in close contact with fire‚ it generates a loud noise similar to a popped piece of popcorn and it blows out the flame. 2. Oxygen B. When manganese reacts with H2O2 small bubbles form around the pieces of manganese and carbonates the whole solution. E. When I put the glowing toothpick in the oxygen gas it caused
