1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The environmental factors that you are testing on the rate of transpiration are the independent variable of this experiment. These independent variables are specifically light‚ fan‚ dark‚ and humidity. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants are things like the type of plant used‚ room

September 11th‚ 2001. My mom lets me sit in her designated chair at the dining table. I am excited with this newfound power. She talks but I do not understand what she is saying. She tells me things might change and to go wash my hands before dinner. I exit‚ but listen in on her conversation with my dad‚ a sneaky practice I do all the time. Dad: You think you won’t get much work now? Mom: (in a firm‚ tone) Ned‚ it destroyed the industry. In March‚ my mom was laid off from her position as an office

chromatography (TLC) is an extremely valuable analytical technique. It provides a rapid separation of compounds‚ and gives an indication of the number and nature of the components of a mixture. TLC can also be used to identify compounds by comparison with known samples‚ to check the purity of a compound‚ or to monitor the progress of a reaction‚ an extraction‚ or a purification procedure. This experiment will introduce you to the mechanics of TLC‚ and the chemical principles behind it. TLC is normally

In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen

accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase‚ which the TLC plates as well as a mobile phase‚ which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result‚ nonpolar substances travel further than polar substances in this process. The separation of a mixture into its components by TLC transpires because the distinctive components of a mixture interact

Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

IFRS 9 Financial Instruments (AASB 9) was issued to replace IAS 39 (AASB 139) Discuss critically the shortcomings and criticisms of IAS 39 (AASB 139) which have given rise to IFRS 9 (AASB 9). How will the application of IFRS 9 (AASB 9) impact on the accounting for financial instruments in financial reports?

Significant or not it affects some or all. For America 9/11 was the biggest tragedy to occur since Pearl Harbor‚ and has changed the course of our nation and for the future. 9/11 being the largest death poll on American soil since the civil war had a great impact on the country. It takes a great force to change the course of a powerful nation and 9/11 had that power to leave the country in shock and change the future for America.

For every cause there is an effect‚ and unfortunately the effects of 9/11 are disturbing. I like to say that everything happens for a reason‚ and the reasons of 9/11 still continue to puzzle the people today.
