3. Pick a uniformly chosen random point inside a unit square and draw a circle of radius 1/3 around the point. Find the probability that the circle lies entirely inside the square.24. A. Let (X, Y) denote a uniformly chosen random point inside the unit square [0, 1]2 =[0, 1] × [0, 1] = {(x, y) : 0 ≤ x, y ≤ 1}. Let 0 ≤ a < b ≤ 1. Find the probability Pr(a < X < b), that is, the probability that the x-coordinate X of the chosen point lies in the interval (a, b)

CHEM 221 Santa Barbara City Steam Distillation of Essential Oils Lab Report.

https://youtu.be/Cj-tqUTCtA8The
following is an outline of what your instructor expects to see in your
lab reports. As long as the order and main titles (presented below in
bold type) are present, the style is completely up to each student. A
carbon copy laboratory notebook is required, and all work should be
recorded directly in the notebook, not on scratch paper, as the work is
performed. The written laboratory report includes the following areas:Name,
Lab section or day/time and the complete title of the experiment should
be written in the provided section on the top of each page.The
Objective should indicate the purpose of the experiment in 1 to 2
sentences be clear and concise. If the experiment involves synthesizing a
compound, meaning you make something new, please include a reaction
scheme. A reagent table labeled as Physical and Chemical
Properties of Reagents. Within this table should be the appropriate
physical and chemical properties such as molar mass, melting point,
boiling point, density, refractive index, amount needed, and at least
one hazard and safety precaution for each substance. You can find this
information in the CRC Handbook of Chemistry and Physics or online at a
credible website, such as sigmaaldrich.com or https://sdbs.db.aist.go.jp
and the proper reference should be indicated below the table.
Calculations of theoretical yield and limiting reagent should be written
below this table if the experiment is a synthesis.Equipment/Apparatus
section will include a list of common glassware or equipment needed,
such as spatula, Erlenmeyer flask etc. OR you may be required to draw
and label the apparatus primarily used in the experiment of the day
unless the apparatus had been used in a previous experiment, such as
distillation. Since you will be observing the experiments in a
video format I want you to write the Procedure according to your
observations and my narration. This way, it will be in your own words
and in a manner that you understand! Yay! It should, however, be written
such that any organic chemist can perform the experiment when using
these procedures. It may be a flow chart, paragraph, or bullet point as
an example. The first time you perform a certain technique, for example,
a distillation, you must describe how to set up and perform the
distillation. If a subsequent experiment requires a distillation, you
may simply state that the liquid was distilled.The above 5
sections are called the “pre-lab” and would typically be due upon
entering the lab, but in this online format will be submitted with the
below sections, called the “post-lab” and will include the following: Data
and Results section is completed during the lab. Include all data
obtained, observations (color changes, emulsions forming, liquid
disappeared, melting point, crystallization), measurements (including
tared masses), and results. Analytical results, such as an NMR spectra
or IR should be attached at the end of the report. Calculations including items such as percent yield, or Rf values etc should be written out completelyThe
Conclusions section should be used to interpret the data obtained. You
should summarize your results of the experiment, including data such as
yields, mp, bp, purity and how you came to this conclusion, % error,
spectral analysis, literature values as well as any other necessary
information needed to identify if the objectives of the experiment were
achieved. You may also state whether or not the procedure was a good
method for making the desired compound and any suggestions on improving
the methods for future experiments. Possible sources of error, and how
that error would affect the overall yield are extremely important to
comment on.

## University of Virginia Equation of Force Balance for Ions Questions

University of Virginia Equation of Force Balance for Ions Questions.

I’m working on a physics multi-part question and need guidance to help me study.

A velocity selector is a device that uses a combination of an electric field and a magnetic field to select particles that are moving at a particular velocity and “eliminate” particles that are moving faster or slower than that velocity. For a velocity selector with fields aligned as below:
– Draw the direction of the force on the ion due to the electric field.
– Draw the direction of the force on the ion due to the magnetic field.
– Derive an equation that will balance the forces on the ion due to the magnetic and electric fields (use Newton’s 2nd law).
– If the magnitude of the electric field is 100 N/C, what does the magnitude of the magnetic field need to be in order to select for 1000 m/s.

## Electoral College, powerpoint, political science homework help

essay order Electoral College, powerpoint, political science homework help.

Many Americans who vote in a Presidential election believe they are
voting directly for a candidate. In actuality, they are voting for a
slate of electors who will cast their ballots in the Electoral College.
These electors ultimately select the President and Vice President. Some
believe it is time to change this process, and elect the President and
Vice President by a direct nationwide popular vote of the people. For
this assignment, please provide arguments on both sides of the equation –
keeping the current Electoral College system or changing to a
nationwide direct popular vote election of the president.Your completed presentation should include at least the following elements:A
comprehensive explanation of the Electoral College and how it works to
elect the President and Vice President of the United States. The
reasons the founders of the United States created an Electoral College
and included it in the Constitution, instead of having a direct
nationwide popular vote election of the President. The total number of Electoral College votes, and how many electoral votes are needed to become President. Provide
an explanation of how electors are divided or apportioned amongst the
various states. For instance, how many electors are apportioned to each
state, and what is the method used for apportioning these electors?
Which states have the most electors, and why? Which states have the
least number of electors, and why? How are the number of each
state’s electors related to a state’s representation in the Congress –
in terms of House members and Senators? Also, who are these “electors”
and how are they selected? What happens after the November
General Election leading up to Inaugural Day? For instance, explain what
happens in each of the state capitols in mid-December and during a
joint session of Congress in early January following the November
General election. Finally, compare and contrast the U.S. system
of electing the President with the system used in another country of
your choice. For instance, how does the selection of the President of
France, or the Prime Minister of Great Britain, or the Chancellor of
Germany, compare and contrast with the system of electing the President
of the United States? 15 slide PowerPoint Presentation
