Benzoic acid (5) is soluble in diethyl ether but not water; however, benzoic acid is extracted from diethyl ether with aqueous sodium hydroxide.

The atmospheric concentration of CO2 gas is presently 390 ppm (parts per million, by volume; that is, 390 L of every 106 L of the atmosphere are CO2). What is the mole fraction of the gas in the atmosphere?

Randomized controlled trials (RCTs) are the strongest research design for establishing cause and effect. Which of the following is the main limitation of RCTs?

a) RCTs may not be ethical for some studies.

b) RCT design cannot control for confounders.

c) Randomized controlled trials may have a disproportionate number of people exposed to the risk factor.

d) Randomized controlled trials are, by their very design, likely to be very biased towards an expected outcome.

A new treatment is developed that prevents death but does not produce recovery from disease. Which of the following will occur?

a) Incidence will decrease

b) Incidence will increase

c) Prevalence will decrease

d) Prevalence will increase

In a small study, 12 women with cervical cancer (cancer of the cervix) and 12 women with no apparent cervical cancer were contacted and asked whether they had ever used the hormone estrogen as a drug. Each woman with cancer was matched by age, race, and weight with a woman without the disease. This is an example of:

a) A randomized controlled trial

b)A prospective cohort study

c) A case-control study

d) A retrospective cohort study

What does gravity always do?

(a) At a given temperature molecules of higher mass have a higher average speed than those of lower mass.
(b) The shape of the molecular speed distribution (ie. relative number of molecules versus speed) changes as the temperature is raised from 0 ◦C to 100 ◦C.
(c) The rates of the urms (root-mean-square speed) of two different gases are inversely proportional to the square-roots of their molar masses.
(d) When a gas is observed to have a negative deviation from the ideal gas behavior, its compressibility factor becomes negative (Z < 0).

Write a compare/contrast essay about the Salem Witch Trials and the McCarthy Hearings using the suggested format below: Suggested format below. You must write 300 words please read paragraph 1- 4 there different

1. Paragraph 1: Introduction -This paragraph should introduce the two topics being discussed and lead into the thesis statement.

2. Paragraph 2: Comparison - This paragraph should examine the similarities you found between the Salem Witch Trials and the McCarthy era. There should be at least three comparisons. You must use clear transition words to move from one example to another.

3. Paragraph 3: Contrast - This paragraph should examine the differences you found between the Salem Witch Trials and the McCarthy era. There should be at least three differences. You must use clear transition words to move from one example to another.

4. Paragraph 4: Conclusion - The conclusion wraps up everything you have proven in your essay. It should restate the thesis in a new way. It should also draw a conclusion based on the information presented. Are there more similarities or differences between the two? What is a conclusion that can be drawn from this information?

SAP Customer Relationship Management (CRM) and Salesforce are two common CRM vendors
with one being a market leader in house CRM and another a market leader in Software-as-aService (SaaS). Compare and contrast these two types of vendors. Make use of reliable and up to
date Internet resources such as articles and publications to gather your information. Remember,
to compare by means to find similarities whereas to contrast means to find the differences
between the SAP CRM and Salesforce. 

Assume you go shopping online at any online store e.g. www.takealot.com, www.amazon.com
and the like. You buy an item and it gets fulfilled by getting delivered to you. Discuss the flows of
information between Marketing and Sales, Accounting and Finance, Supply Chain Management,
and Human Resources at a typical online store

In a steady flow, a liquid move between two sections namely Section 1 and Section 2. Data were gathered. For section 1 : Area= 10ft^2 , speed= 100ft/min, specific volume= 4ft^3/lb. For section 2: Area= 2ft^2 , density= 0.2 lb/ft^3. Find the mass flow rate in lb/s.

In this section, please list at least three criteria that must be met by your train design. Also include any limitations that could prevent it from getting its cargo to the station.

A hydrochloric acid solution is standardized by titrating  0.2329 of primary standard Na2CO3 (105.96) to a methyl red end  point by boiling the carbonate solution near the end point to  remove the carbon dioxide. If 42.87 ml acid is required for the  titration, what is its molarity?

The attached figure shows the electric field inside a cylinder of radius R=3.0mm. The field strength is increasing with time as E = 1.0x10^8 t^2 V/m (where 't' is in seconds). The electric field outside the cylinder is always zero, and the field inside the cylinder was zero for t < 0.

a: Find an expression for the electric flux through the entire cylinder, as a function of time.

b: Find an expression for the magnetic field strength as a function of time, at a distance r<R from the center.

c: Find an expression for the magnetic field strength as a function of time, at a distance r>R from the center.

d: Draw a picture showing the magnetic field lines inside AND outside the cylinder.
