Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

search- specific latent heat Q. Value for the specific latent heat of fusion of water: Specific latent heat is where the amount of energy (in joules) needed to change the state of 1Kg of a substance is called its specific latent of heat. You can calculate the amount of energy needed using the equation: energy (J) = specific latent heat (J/Kg) X mass (Kg) Material Specific heat of fusion (J/Kg) Specific latent heat of vaporisation (J/Kg) Water 334000 2260000 Lead 24500 871000 Ethanol

were conducted to find the specific heat of a metal as well as the heat of solution of a solid. Both experiments required the use of calorimetry to measure heat flow and temperature change. The specific heat of the metal was found by heating it in boiling water before transferring it to the calorimeter that was partially filled with water. After shaking the calorimeter‚ the temperature change was measured and recorded. This information was used to calculate the specific heat. The heat of solution

How do you design and conduct a specific training program ? Answer : To design a program a trainer has to assess several factors. First the trainer should understand the need of the training. Then assess the training needs. Finally‚ according to the assessment‚ design a specific type of training programme. The training and development programme for workers‚ supervisors and mangers has to design separately. Programme Designing. The designing of the programme for the workers is normally done

EApplication and Analysis The article deals with implementation and removal of a specific subsidy. A specific subsidy is the specific amount paid by the government to a firm per unit output. Graph 1 Graph 1 shows the removal of the specific subsidy for diesel. The demand of diesel is relatively inelastic. Price elasticity of demand is a measure of how much the quantity demanded of a product changes when its price changes. As we can see‚ the market is in equilibrium with Q1 being
