Experiment 6 Mole Ratio in a Chemical Reaction Background: Mole ratios of reactants are often times figured out by the use of the other products in a chemical equation. However‚ in the instance that the products’ mole ratios are unknown‚ it can be determined through the experiment. This method is called continuous variations. In this lab‚ I determined the mole ratio between Sodium Hypochlorite and Sodium Thiosulfate by using continuous variations of ratios in a given volume. This reaction was

Profitability Ratios Return on Capital Employed (ROCE) or Return on Equity (ROE) Numerator – the net profit or income‚ usually taken before tax. Capital Employed or Shareholders Equity - Designed to indicate the effective use of the shareholders capital in the business with respect ot the net profits that they have generated over the period of concern. Net Profit/Income Percentage or Return on Sales Helps to identify the impact of administrative‚ selling and distribution costs on profit

traded in Africa. The trans-Saharan trade routes were a vast trade network that reached across the continent‚ on which diverse goods and resources were traded‚ and knowledge‚ ideas‚ and religion spread in a phenomenon known as cultural diffusion. Cultural diffusion that occurred along the trans-Saharan trade routes shaped the development of culture in medieval Africa. The trans-Saharan trade routes provided African people access to goods and resources that were not local to their

simple diffusion and understand how to make % solutions. Exercise 2 demonstrated the principle of osmosis: observing the movement of water by osmosis from an area of lower concentration of a solute to an area of higher concentration of a solute. Materials and Method: Refer to pages 47-51 of Bio 203L Lab Manual. Results/ Discussion: The effect of the chloride ion on its rate of diffusion in agar means it will diffuse faster because it is more concentrated. We graphed the diffusion of chloride

CAPACITY Lung capacities are combinations of specific lung volumes. The lung capacities are measurements of two or more volumes. The total lung capacity (TLC) is a measurement of the total amount of air that the lung can hold; normally it is 6 litters for adult male and 4.2 litters for an adult female. The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. The Residual Volume (RV) is the amount of gas remaining the lungs after a maximal

One of these includes the southern region of Bangladesh. The main source of freshwater in Bangladesh comes from the Ganges River. Water and soil pollution is now one of the major problems occurring in Bangladesh and the Ganges River Basin. It has been an ongoing problem for many years so it is not like it

probes successfully landed on the surface of the Venus. However‚ the essential equipment on probes was damaged‚ leading to that it failed to get insight into the surface of the Venus. While‚ on 17th August 1970‚ with the experiences from the previous two attempts‚ "Venus 7" lander completed their missions on the surface of the Venus successfully. The lander gauged the atmospheric pressure on the surface of the Venus‚ which illustrated that the pressure on the Venus’ surface was at least 90 times stronger

Lab Report on Osmosis and Diffusion Biology 1‚ Period 3 March 15‚ 2010 Lab Team: Jason Perez‚ Kicia Long‚ Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing. Materials Used 2.5 cm dialysis tubing 15% glucose

Plants were cut at the soil surface‚ leaves were separated from the plants‚ covered with blotting paper to keep the leaf intact and retain its original shape and were brought to the laboratory. Leaf area was measured immediately after
