Station 2: Density column In the graduated cylinder, you have molasses, water (blue), corn oil, and ethanol (red). They have the following densities: Substance Molasses Water Corn Oil Ethanol Density 1.45 g/mL 1.0 g/mL 0.92 g/mL 0.79 g/mL Polarity Polar Polar Nonpolar Polar Viscosity High Low Low Low 1. Explain why the column is arranged in the order it is according to density.

Can you give me a detailed step by step process of how to do this please, thank you !

Impure Compound X was found to have a melting point range of 106-114 oC. What do each of these numbers (104 and 112) represent?

You are interested to know the Q10 value for mean heart rate (# of beats/10 sec) for a species of crab for the temperature interval of 25°C - 35°C. To find this value, you collect data for these six temperatures and calculate mean heart rate (# of beats/10 sec) for each temperature. Here is the data: 10°C 15°C 20°C 25°C 30°C 35°C Mean Heart Rate (# 23.67 23.89 24.33 27 35.89 37.78 beats/10 sec) What is the Q1o value for heart rate (# of beats/10 seconds) for the temperature interval of 25°C - 35°C? Round your answer to two decimal places.

Hello I need help on these two quick questions. Thank you.

If you have already had an eye examination at an ophthalmologist, you probably noticed that you had to use eyedrops at first. The solution is then dripped into the eyes of atropine (the poison of the poison ivy), which dilates the pupils - which makes it possible easier tracking of the fundus. For more complicated procedures they use substances that work longer - for example, tropicamide. Like all similar substances tropicamide also affects the central nervous system and thus became one of the ingredients of the infamous "crocodile" drug. In this task we will look at its synthesis: d) Intermediate IN2 is converted to intermediate IN3 through 3 steps, the procedure is as follows: It is necessary to prevent the formation of by-products. 1. What would happen if we attempted the direct alkylation of IN2 to IN3 using ethyl iodide in the presence of potash? 2. Write the structure of at least 2 byproducts VP1 and VP2 that would they could have arisen under such conditions. e) In the synthesis…

Like all similar substances tropicamide also affects the central nervous system and thus became one of the ingredients of the infamous "crocodile" drug. In this task we will look at its synthesis: b) Tropicamide is prepared by the reaction of intermediates IN3 and IN5. The resulting mixture after reaction is diluted with water and slightly warmed. from the mixture, tropicamide crystallizes, and is formed with the general formula C17H20N2O2. Write its structure. c) The IN1 intermediate is a diazonium salt and these are generally unstable in the presence of nucleophiles. Compare the stability (i.e.…

For this statement, answer True or False and explain your answer briefly. Polarity is the only characteristic used in liquid-liquid extraction to isolate a poison from the biological matrix.

Question 7/19 > NEXT A BOOKMARK Almonds are edible seeds that grow on trees. Wild almonds typically have a bitter taste caused by a chemical in the almond. If an organism eats wild almonds, a chemical reaction occurs that releases the bitter taste. However, a genetic mutation in the almond tree can occur that prevents wild almonds from producing the bitter taste. Which statement describes how this type of mutation could affect these wild almond trees? 7 A This mutation could increase the population of wild almond trees. B This mutation could increase the life span of wild almond trees. (c) This mutation could decrease the rate of the production for wild almond tree P Type here to search DELL
