Answer: C.  A new compound formed when nitrogen and hydrogen chemically reacted.

Explanation:

Due to the temperature increase, the atoms of both Nitrogen and Hydrogen reacted chemically with one another and formed a new compound which was still colorless but now had a strong odor as well.

This new compound is known as Ammonia with the chemical composition NH₃. It is formed when Hydrogen and Nitrogen react chemically. Ammonia is a colorless gas with a sharp strong odor.

Why would a sole proprietorship or partnership need to submit a DBA form for the company?
Feliz [49]
If you’re a sole proprietorship  or general partnership, you’ll need to file a DBA if you want your company to operate under a name that’s not your full, legal name, or your partner’s name. That’s because sole props and GPs are unincorporated, and they don’t need to file entity formation papers, and a business entity name, with the state. (Though they do still need to acquire the necessary business licenses and permits.)

So, they and their business are one in the same entity—which means they and their business have the same name, too—unless they file a DBA. 




I hope it helped you!

You have $250,000 to invest in a stock portfolio. Your choices are Stock H, with an expected return of 12.9 percent, and Stock L
prisoha [69]

Answer:

The investment in stock H will be $104837.5 while the investment in stock L will be $145162.5

Explanation:

The portfolio return is the weighted average return of the individual stocks that form up the portfolio. The weightage of each stock in the portfolio is the investment in a stock as a proportion of investment in the portfolio.

Let x be the weightage of Stock H.

Weightage of Stock L will be (1-x).

Portfolio return = wH * rH  +  wL * rL

Plugging in the values,

0.111 = x  * 0.129   +   (1-x) * 0.098

0.111 = 0.129x  +  0.098  -  0.098x

0.111- 0.098  =  0.031x

0.013 / 0.031  = x

x = 0.41935 or 41.935% rounded off to 3 decimal places

(1-x) = 1 - 0.41935  =  0.58065 or 58.065%

Investment in Stock H = 250000 * 41.935%  =  $104837.5

Investment in Stock L = 250000 * 58.065%  =   $145162.5
