Feelings of sadness:

A) Sadness can occur within anybody, not just a symptom of depression. This option is out of the question, since it is wrong.

B) Feelings of sadness are usually linked to depression when felt over a long period of time. Studies say that sadness is only a little part of depression, while you mostly feel rejected, hopeless, and worthless. Looking at the other options, this would be the most reasonable answer.

C) This CAN be true in some ways, but panic attacks can be triggered by so many things. The #1 reason is usually when you're nervous or anxious. Panic attacks can even happen out of the blue. Sadness can lead to panic attacks, but not usually. I would say no for this option.

D) Sadness should NOT be ignored when they last over a long period of time. If you are sad for a certain time period, you should look into talking to somebody about the issue. This option is obviously false.

Out of the choices, two out of four were reasonable, but I would have to go with B) are one of the major symptoms of depression.

What are the roles of producers, primary consumers, secondary consumers, tertiary consumers for the trophic levels in the energy
Nesterboy [21]
     This question is more for Biology than Chemistry, but the role of producers is to make energy (food) to be consumed. In a pyramid diagram, the producers would be at the bottom. Now going up the pyramid, the primary conumers are the first to consume producers and obtain energy from them. As you go up the pyramid, the secondary consumers will consume the primary consumers as a way to obtain energy, and the same goes for tertiary consumers towards secondaries.

As you go up the energy pyramid, you will notice a trend that there is less energy being obtained from each consumer. In other words, the producers will ALWAYS have more energy than the tertiary consumers.

I hope this answers your question.

A. At STP, what is the volume of 708 mol of nitrogen gas? 708 mol = 708 mol X L B. A sample of hydrogen gas occupies 14.1 L at S
elena-14-01-66 [18.8K]

Answer:

A. 15859.2 L or 15900 L

B. 0.629 mol

Explanation:

At STP, one mole is equal to approximately 22.4 L

L or mL is volume, so you are attempting to solve for L or mL.

A.

708 mol x (22.4 L/1 mol) = 15859.2 L (w/ significant figures included - 15900 L)

B.

(14.1 L) x (1 mole/ 22.4 L) = 0.629 mol.
