6. Find the partial pressures of the gases in a mixture with a total pressure of 101.3 kPa, if there are 7.8 mole of

ikadub [295]

Answer:

Explanation:

Total mole of gases = 7.8 + 2.1 + .09 + .01 = 10

the partial pressures of the gases in a mixture

= mole fraction x Total pressure

mole fraction = mole of a gas in the mixture / total mole

partial pressure of Ng = $\frac{7.8}{10} \times 101.3 kPa$

= 79.014 kPa

partial pressure of O = $\frac{2.1}{10} \times 101.3 kPa$

= 21.273 kPa .

partial pressure of Ar = $\frac{.09}{10} \times 101.3 kPa$

= .9117 kPa .

partial pressure of Co = $\frac{.01}{10} \times 101.3 kPa$

= .1013 k Pa .

Answer:

Without the hydrosphere, the atmosphere will no longer be able to carry up the evaporated water, as well as pour down the water, leaving the biosphere to rot away. The hydrosphere works with the Biosphere to provide the requirement of water to the organisms needs, as well as the hydrosphere assisting in photosnythesis.

A body travels 10 meters during the first 5 seconds of its travel, and it travels a total of 30 meters over the first 10 seconds

Mariulka [41]

Answer:

$\large \boxed{\text{C. 4 m/s}}$

Explanation:

At 5 s the body has travelled 10 m.

Between 5 s and 10 s, the body reached 30 m.

Distance travelled = 30 m - 10 m = 20 m

Time = 10 s - 5 s = 5 s

$\text{Speed} = \dfrac{\text{ distance}}{\text{time}} = \dfrac{\text{20 m}}{\text{5 s}} = \textbf{4 m/s}\\\\\text{The average speed between 5 s and 10 s is $\large \boxed{\textbf{4 m/s}}$}$
