success‚ it must reduce some economic‚ social and environmental damages‚ while being affordable for the region of use. An example of a strategy that modifies the event of a tropical storm is cloud seeding. While cloud seeding (using dry ice or silver iodide to trigger precipitation e.g. to maintain sunny conditions at the Beijing 2012 Olympics) has the potential to prevent any social‚ economic or environmental losses at all through the dissipation of a storm over a safe region‚ it has a number of drawbacks

First‚ 2 mL of was reacted with approximately .5 g of KI in an Erlenmeyer flask to form and a hypoiodite species. The second step is the reaction between another molecule of and hypoiodite‚ which results in reformation of the catalyst‚ potassium iodide. The catalyst is used to speed up the reaction by decreasing the activation energy. In addition‚ the catalyst can regenerate itself to be used again till the reaction runs to completion. Overall‚ the reaction is (l). Oxygen gas will be collected

What are the exceptions? Sodium chloride‚ sodium iodide‚ and sodium sulfates generally do not form precipitates. One exception in our results with all three of these was when they were each combined with Fe(NO3)3 (iron nitrate) in which all three yielded brown precipitates. E - Which cations generally

Purpose: The purpose of this lab is to develop a deeper understanding of LeChatelier’s Principle by observing several systems at chemical equilibrium and interpreting the effects of varying concentrations and temperature. The principle states that if systems at equilibria are altered or disturbed in any form‚ the equilibria will shift to reduce the disturbing influence ( Catalyst‚ 186). In a 3 part experiment‚ we analyzed the outcome of changes in reactant and product concentrations‚ equilibrium

Demo write up: #1 The plastic tablet that gets placed into the water causes the water to spin like a tornado. Then when dry ice is added the water starts to spin and create smoke‚ the color of the water goes from dark green to light green. There is probably a chemical in the dry ice that is reacting with the universal indicator which is causing the substance to change colors. Hydrochloric acid changes the color of the mixture and makes it green to yellow but when you add more hydrochloric acid

Sodium Bromide which is slightly toxic if inhaled or ingested may cause serious eye damage if in contact. Sodium Iodide may cause serious eye damage‚ corrosion or irritation causes skin irritation. Silver Nitrate may cause skin corrosion or irritation also may cause severe skin burns and eye damage‚ very flammable keep away from heat‚ sparks‚ open flames‚ and hot surfaces
