Question
Can i get help with the two examples below

Transcribed Image Text:2.18 When we write arrow-pushing mechanlsms Involving proton
transfer, It Is often difficultto keep track of aclds and bases. In general,
when we wrte arrow-pushing mechanlsms that occur under ackdkc
conditions, It Is best to represent the add and conjugate base as H-A
and A-, respectively. Conversely, for mechanisms that occur under
basic conditions, It Is best to represent the base and conjugate acld
as Band B-H. For reactions that occur under neutral conditions, you
can choose elther H-A/A or B:/B-H
A Suggest a plauslble arrow-pushing mechanlsm for the following
reaction, using H-A as the acld and A-as the conugate base

- A student follows a lab protocol that asks them to make an ‘alcohol’ solution for an experiment. They make a 1.00 L solution by adding 575 g of an alcohol to water. Later they realize that there were three different alcohols sitting on the lab bench and they’re not sure which one they used. The alcohols are: methanol (CH3OH), ethanol (C2H5OH), and butanol (C4H9OH). They decide to boil the solution and they find that it boils at 106.40 °C. Using this information determine which alcohol the student used to make their solution. Density of water is 1.00 g/mL, Kb = 0.513 K/mc. Hint: you need to consider the molar masses of your alcohols.arrow_forwardMuch of Earth's history can be unraveled studying sulfur. Sulfur can be used as "geothermometer". The ratios of stable sulfur isotopes change with the temperature of Earth's processes. For example, igneous systems deep inside the Earth occur at very high temperatures, hydrothermal systems occur at intermediate conditions, and sedimentary rock weathering occurs at low temperatures. The composition of stable sulfur isotopes varies across the 1000 degree temperature range. 10. How many peaks would be seen in the mass spectra for such a study?

In each case, decide whether there is a net force acting on the object outlined in green. If there is a net force, decide whether it pushes the green-ring object to the left or right. Then select the appropriate button under the sketch. For example, if there is a net force pushing the green-ring object in the first sketch to the left, select the left button under the first sketch. If there is no net force on the green-ring object in the second sketch, select the middle button under the second sketch. And so on. I Don't Know Submit X ✪ n tv © 2023 McGraw Hill LLC.

Water is made up of hydrogen and oxygen atoms (H2O); however, biological life in water depends on another form of oxygen. These organisms need molecular oxygen (O2), which they use to perform aerobic respiration. This molecular oxygen fits into spaces between water molecules and is available for aquatic organisms to use. How do you think molecular oxygen gets into the water? Choose two of the following choices. Select all that apply: From the oxygen atoms that are part of the water molecules. From oxygen that dissolves into water from the atmosphere. From oxygen that is given off by aquatic organisms during respiration. From oxygen that is given off by aquatic plants during photosynthesis.arrow_forward

It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry. Q.5 - Preen oil is actually a complicated mixture of many different organic compounds, such as the structure seen previously.. Ornithologists have determined that birds often use preen oil compounds for scent recognition. Below, several different chemicals isolated from preen oil are shown, along with their vapor pressures at room temperature. p-cymene has the highest vapor pressure, meaning it is the most easily evaporated compound of the three listed. Explain why p-cymene has a higher vapor pressure at room temperature compared to the other compounds. Make sure to explain what holds the p-cymene in the sample. (Image attached)arrow_forward
