The writer is considering adding the following sentence to the end of the second paragraph (sentences 3-5). Furthermore, the mov
Nataly_w [17]

This sentence should not be included because it is not explained why these organizations have a negative perspective.

<h3>What is paragraph 2 about?</h3>

Paragraph 2 focuses on the positive points or the benefits of vegetarianism. This idea is stated in "Many studies have found that vegetarianism has important health benefits".

<h3>Should the sentence be included?</h3>

The sentence presented states some health organizations have created a negative perspective about being vegetarian. This idea is indirectly related to the benefits of being vegetarian.

Moreover, this idea is not completely explained, for example, there are no reasons why these organizations have this perspective. Based on this, the sentence should not be included.

Note: This question is incomplete because the text has not been provided; here is the missing section:

(3) Many studies have found that vegetarianism has important health benefits. (4) For example, a vegetarian diet is connected to lower rates of heart disease and diabetes as well as lower cholesterol levels. (5) Some studies have also shown that cancer rates are lower in vegetarians than in meat-eaters and that vegetarians tend to live longer than nonvegetarians.

What is the molar solubility of agcl (ksp = 1. 80 × 10⁻¹⁰) in 0. 500 m nh₃? (kf of ag(nh₃)₂⁺ is 1. 7 × 10⁷)
Hoochie [10]

Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.

<u>Given the following data:</u>

  • Ksp of mg(oh)₂ = 1.8 × 10⁻¹⁰
  • Concentration of NH₃ = 0.500
  • Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷

<h3>How to determine the molar solubility.</h3>

First of al, we would write the properly balanced chemical equation for this chemical reaction:

                          AgCl(s)\rightleftharpoons Ag^{+} (aq)+ Cl^{-}(aq)       Ksp = 1.8 × 10⁻¹⁰

                AgCl(s) + 2NH_3(aq)\rightleftharpoons  Ag(NH_3)_2^{+}(aq)   Kf = 1. 7 × 10⁷

K = Ksp × Kf

K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷

K = 3.06 × 10⁻³

Mathematically, the Ksp for the above chemical reaction is given by:

K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}

x = 2.77 × 10⁻² M.

Which of the following scenarios are potential candidates for use of the ANOVA F-test? Check all that apply.
m_a_m_a [10]

Hello. You forgot to enter the answer options. The options are:

A) We compare homework hours for male and female high schools students.

B) We compare job status (have a job: yes, no) for male and female high school students.

C) We compare hours working at a job for high school student athletes in three sports (basketball, track and soccer.)

D) We compare television viewing hours for high school students with and without a curfew.

Answer:

C) We compare hours working at a job for high school student athletes in three sports (basketball, track and soccer.)

Explanation:

The ANOVA F-test is a type of analysis of variance used in systems that wish to compare the average of three, or more, different groups. With that, we can affirm that the letter B is the correct option, since it is the only option that presents the comparison between three groups.

The ANOVA F-test is used to compare the average between the three groups and determine if there is a statistical equality between them, or if some of them are above or below the average, showing that the groups are not statistically similar.
