Periodic Table Trends Quiz 1. The most reactive metals are located in the lower left hand corner of the periodic table 2. Which of the following atoms listed below has the largest atomic radius? Ca 3. Compared to the atomic radius of a rubidium atom‚ the atomic radius of a strontium atom is smaller. The smaller radius is primarily the result of the strontium atom having greater effective nuclear charge 4. An element is most likely to have properties similar to those of another

Fact A Place at the Table (Silverbush and Jacobson‚ 2013) was about the hunger in America‚ including programs that involve food stamps and school lunch programs. It discussed the need and increase for healthy food in America and the lack of food security. The movie talked about women in America who are currently struggling to make ends meet due to making “too much” money according to standards to meet the need for food stamps. It also shows several families who are trying to make ends meet while

Abstract The following experiment details the effect of different concentrations of catalase on the production of oxygen and water through the breakdown of Hydrogen Peroxide. In this experiment paper disc where coated in varying concentrations of catalase‚ 0‚ 25‚ 50 75 and 100%. The time taken for the disc to float between two markers on the side of a glass was then recorded. This experiment demonstrates that the higher the concentration of enzyme used the greater the production of oxygen on the paper

The Spectrophotometer Determination Of Protein Concentrations And The Effects Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth
