Introduction Silver Iodide is an inorganic compound represented by the formula AgI that is used in cloud seeding‚ photography‚ and can also be used as an antiseptic. These are the three main ways the compound

Relative Humidity Lab 1. Yes‚ our relative humidity was different for the two locations because the temperature in the building was lower than the temperature outside. 2. The psychrometer has a "sock" on the bulb of the thermometer. You get the sock wet and twirl the thermometer around for 30 seconds. If the temperature dropped then you spin it again for 15 seconds. Then you subtract the temperature of the psychrometer from the starting temperature and that is the difference. Then you must look

Title: Food Energy Lab Report Date of Activity: 8-28-13 through 8-29-13 Purpose: The purpose of the lab was to measure the amount of energy contained in a gram of certain foods. Hypothesis/Prediction: I hypothesize that some of the foods are going to be difficult to burn. Procedure: 1. Weigh the weight of empty can and food items. 2. Fill can approximately one third full of water. 3. Weigh the can after water is in the can. 4. Take the temperature of the water in the can. 5. Place the

Maricela Sandoval Period 2 10/27/12 Title of Lab: The Melting Temperature of a Pure Substance Purpose: The goal of this experiment was to find the melting point of Paradichlorobenzene and to observe the freezing/melting of a substance. The purpose was to also observe an endothermic and exothermic process. Introduction: The uses of Paradichlorobenzene are mainly as a fumigant for the control of moths‚ molds‚ and mildews‚ and as a space deodorant for toilets and refuse containers. It is also

used during the experiment are as follows; * Marcet boiler * Bunsen burner * Gauge pressure * Thermocouple * A mercury-in-glass thermometer * A stop watch PROCEDURES * I heated the boiler with both taps open. When boiling started‚ I closed the side tap. * I allowed the steam to escape from the top tap for one minute I closed the top tap. * I heated the boiler with all taps close and took readings of temperature for the selected pressure as it boils. * I

the shorter amount of time it takes to crystallize. The less amount of KNO3 you have‚ the longer it takes to crystallize. In the end‚ my hypothesis was correct because when we added more KNO3 it took less time to crystallize. We had 0 errors in our lab everything went

Effect of pH on Enzyme Activity Athenaa Jeyachandran Mr.Menes Course Code January 21st‚ 2013 The Effect on Enzyme Activity Due to Temperatures Purpose: The purpose of this lab experiment is to examine how different temperatures affect enzyme activity using hydrogen peroxide. Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes

also known as glucose must be present within the yeast. When the yeast fermentation solution was used it made it easier to measure the effects of temperature on the yeast fermentation and the respiration or breathing room of the yeast and meets the lab requirements. Also yeast when combined with sugar excretes carbon dioxide in which was measured through the process of water displacement. Water displacement is when something is placed in water and the amount of water is measured (Hughes‚ 2005).

minutes of being placed under the same heat lamp‚ the soil will absorb heat faster‚ therefore ending with a higher temperature than the water. Materials • 2 petri dishes • Soil • Water • 2 thermometers • Heat lamp Procedure 1. Design lab tables. 2. Record mass of petri dish and then add enough soil to fill it to the brim. Record mass again. The difference is the mass of the soil sample. 3. Record the mass of another petri dish and fill it with water. Record the mass again. The difference
