A tank has a total pressure of 285 kPa and contains Hydrogen, Oxygen, Carbon dioxide, and Neon. If Neon has a partial pressure o

f 14 kPa, carbon dioxide is 13 kPa, and Oxygen has a partial pressure of 157 kPa, what is the partial pressure of Hydrogen?

Answer:

Lets the total pressure is Pt and the individual gases are designated as pH2, pCO2, pNe, pO2.

Pt =  pCO2+ pNe+pO2+ pH2

285KPa = 13 KPa+ 14 KPa + 157 KPa +pH2

Now add the partial pressure of CO2, Ne and O2 which is equal to 184 KPa.

285 KPa = 184 KPa + pH2  

Now subtract the individual pressure of each gas from thje total pressure.

285 KPa - 184 KPa = pH2

                101 KPa = pH2

The partial pressure of hydrogen is  101 KPa.

What is the function of peristalsis?
Kisachek [45]

Answer:  A

Explanation

The digestive tract carries out the function of peristalsis by moving food through the system.  Peristalsis also removes excess liquid from the body.  Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis.  Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.

An iron ball is dropped onto a pavement from a height H. If half of the heat generated goes into warming the ball, find the temp
mr Goodwill [35]

The given question is incomplete. The complete question is as follows.

A 10 kg iron ball is dropped onto a pavement from a height of 100 m. If half of the heat generated goes into warming the ball,find the temperature increase of the ball. (In Sl units, the specific heat capacity of iron is 450 J/kg.C degree).

Explanation:

In the given case, when the ball comes in contact with the pavement then its kinetic energy will be equal to potential energy of the ball before it was dropped. Half the K.E heats the ball.

As K.E = P.E = mgh

So, mgh = 10 \times 10 \times 100 = 10,000 joules

And, half of this is 5,000 joules

As we know that

             Q = m \times C \Delta T

          5000 = 450 \times 10 \times \Delta T

\Delta T = \frac{5000}{4500}

              = 1.11 degrees

Also, in the given situation

          \frac{mgh}{2} = m \times C \times \Delta T

Since there is an m on both sides of the equation, we will divide both sides by m  and the resulting equation will be as follows.

        \frac{gh}{2} = c \times \Delta t

As, the result is independent of mass which is why the result is the same for any ball of any mass.

How does flame spread over liquid depend on the flash point?
zvonat [6]
If the liquid is at or above its flash point, the flame spread rate is fast, and the entire pool is engulfed within seconds. ... As the liquid temperature decreases, flame radiation must both heat the liquid to the flash point temperature and supply the heat of vaporization.

Then if I have 210.1 g barium chloride with 45g potassium...how many grams of potassium chloride will I produce?
Katarina [22]

Answer:

  85.8 g

Explanation:

The molar mass of BaCl₂ is 208.233 g/mol, so 210.1 g is about ...

  210.1/208.233 ≈ 1.009 mol

The molar mass of K is about 39.089 g/mol, so 45 g is about ...

  45/39.089 ≈ 1.1509 mol

The balanced equation seems to be ...

  BaCl₂ + 2K  ↔ 2KCl + Ba

This reaction requires 2 moles of potassium for each mole of barium chloride, so the available potassium limits the reaction. The result is as many moles of potassium chloride as there are moles of potassium.

The 1.1509 moles of KCl, at 74.551 g/mol will have a mass of about 85.8 g.

The reaction produces 85.8 g of KCl.

When water is heated in an ocean the liquid water changes from and turns into?
sasho [114]
Hello!

The answer is Evaporation

When you add heat to water, it boils, releasing gas into the air. This is called Evaporation. The water changes from a liquid to a gas.

Hope this helped!
