Eukaryotes are multicellular organisms. So, just about every ant, bee, and termite you can think of qualifies. Also, if you consider herds applicable, you can add elephants, zebras, and lions.

You have 4 moles of oxygen gas in a flask. 4 moles of helium gas is added. What happens to the total pressure of the gases in th
ASHA 777 [7]

Answer: The correct option is (c). The total pressure doubles.

Solution:

Initially,  only 4 moles of oxygen gas were present in the flask.

p_{O_2}=Tp_1\times X_{O_2}  (X_{O_2}=\frac{4}{4}) ( according to Dalton's law of partial pressure)

p_{O_2}=Tp_1\times 1=Tp_1....(1)

Tp_1= Total pressure when only oxygen gas was present.

Final total pressure when 4 moles of helium gas were added:

X'_{O_2}=\frac{4}{8}=\farc{1}{2},X_{He}=\frac{4}{8}=\frac{1}{2}

partial pressure of oxygen in the mixture :

Since, the number of moles of oxygen remains the same, the partial pressure of oxygen will also remain the same in the mixture.

p_{O_2}=Tp_2\times X'_{O_2}=Tp_2\times \frac{1}{2}

Tp_2= Total pressure of the mixture.

from (1)

Tp_1=Tp_2\times X'_{O_2}=Tp_2\times \frac{1}{2}

On rearranging, we get:

Tp_2=2\times Tp_1

The new total pressure will be twice of initial total pressure.

Examining the figure, how many orders of magnitude larger is a person than a bacterial cell?
TEA [102]
This question is repeated. I will copy the same answer provided by myself.

Well you did not show the figure, but I can show you how to do it.

Suppose the person is 6 feet tall and the bacteria cell is 1 micrometer in length.

So, put both magnitudes in the same units. I will use meter.

Person: 6 feet * 0.3048 m / foot = 1.8288 m, which in orders of magnitud is about 2 m

Bacteria cell: 1 micrometer * 1 m / 1,000,000 micrometer = 1 * 10 ^ -6 m.

Now divide: 2m / 10^ -6 m = 2,000,000

So a person is about 2 million times larger than a bacteria cell.

If the numbers in your figure are different you can use the same method to get a new result according to your figure.

A container with an initial volume of 1.0L is occupied by a gas at a pressure of 150kPa at 25'C. By changing the volume, the pre
Archy [21]

Answer:

Final Volume = 0.31L

Explanation:

Initial volume V1 = 1L

Initial pressure P1 = 150kPa

Initial temperature, T1 = 25'C + 273 = 298K

Final Pressure P2 = 600kPa

Final Temperature T2 = 100'C + 273 = 373K

Final Volume V2 = ?

The combined gas law is given as;

P1V1 / T1  = V2P2 / T2

150 * 1 / 298 = V2 * 600 / 373

V2 = 55950 / 178800 = 0.31L
