Answer:
22.49 g of NH3
Explanation:
The balanced equation for this would be:
3H₂+N₂ → 2NH₃
So let's take note of this:
We will need 3 moles of H₂ to produce 2 moles of NH₃.
Now let us convert:
First we determine the molar mass of H2:
Element:
number of atoms x molar mass
H = 2 x 1.01 g/mol = 2.02 g/mol
Let's see how many moles of H2 there are in 4.00g
Now we can see how many moles of NH₃ we can make given the ratio and convert it again to grams by getting the molar mass of NH₃:
This means that with 1.98 moles of H₂, we produce 1.32 moles of NH₃
So let's get the molar mass of NH₃ so we can convert it to grams:
N = 1 x 14.01 = 14.01
H = 3 x 1.01 = 3.03
17.04g/mol
Answer:
Monitoring and Controlling
Explanation:
Note that, in Project management process stages there are typically five phases:
- initiating,
- planning,
- executing,
- controlling and
- closing.
However, from this scenario in which Cheryl is watching the weather forecast for an outdoor senior picnic project, it shows that she is monitoring and trying to control all aspects of the planned picnic project against the risk of bad weather.
The form of organization must the project manager be working in Functional.
<h3>What is the meaning of organization?</h3>
Organization refers to the group of the people working together in order to achieve organizational goal. The aim of every organization is maximization of the profits.
In the above case, the project manager is trying to complete a software development project but is unable to get the attention on the project. all the resources are under completion of the different works.
This implies that form of organization must the project manager be working in Functional because he has little powers to make the use of the resources.

Answer:
the Expected rate of return will be 8.2%
the variance will be 0.001296
Explanation:
We will calculate the Expected Rate of Return which is the sum of the wieghted return based on their probabilities:
return of 0.15 probability 20% = 0.03
return of 0.07 probability 70% = 0.049
return of 0.03 probability 10% = 0.003
expected return = 0.082 = 8.2%
Now to calculate the variance we do:
∑(rk-ERR)^2 x pk
The sum of the difference between the expected rate and the escenario rate, power two, and multiply by their posibility
the variance will be: 0.001296
Answer: The correct answer is "B. may be less than the variance of the least risky stock in the portfolio.".
Explanation: If a stock portfolio is well diversified, then the portfolio variance may be less than the variance of the least risky stock in the portfolio.
This occurs because diversifying the risk results in a lower risk in the total portfolio.
