EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

(CDs) increased from 10 to 11‚ the quantity of CDs demanded decreased from 100 to 87. What is the price elasticity of demand for CDs Is demand elastic or inelastic 2. Explain why the demand for residential natural gas (gas used for heating‚ cooling‚ and cooking) is more elastic than the demand for residential electricity. 3. Would you expect the demand for a specific brand of running shoe to be more elastic or less elastic than the demand for running shoes in general Why 4. For each

Importance of maintenance Maintenance of air conditioning is important to prevent health and safety issues and keep the air clean and prevent break downs. Heating‚ ventilating‚ or air conditioning units for repairs entail significant costs‚ so it is important to avoid future expenses. Older air conditioners may still be able to offer years of relatively efficient use. However‚ making older air conditioner last requires performing proper operation and maintenance.

Unit 1 This scheme of work suggests possible teaching and learning activities for each section of the specification. There are far more activities suggested than it would be possible to teach. It is intended that teachers should select activities appropriate to their candidates and the curriculum time available. The first two columns summarise the specification references‚ whilst the Learning Outcomes indicate what most candidates should be able to achieve after the work is completed. The Resources

colored jars had the highest emissivity (or absorbed heat the fastest) & which colors radiate heat the fastest by performing independent tests for heating & cooling the colored jars. Methods/Materials Nine of the 10 small jars were painted on the outside with different colors of enamel paint. The 10th jar was used as the control variable. For the heating testing‚ the colored jars were divided into 3 groups. Group 1: red‚ blue‚ yellow; Group 2: gold‚ silver‚ black; Group 3: white‚ green‚ purple
