Which gas will effuse at the rate closest At a particular pressure and temperature, nitrogen gas effuses at the rate of 79mLs. U
Contact [7]

Answer : The rate of effusion of sulfur dioxide gas is 52 mL/s.

Solution :

According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.

R\propto \sqrt{\frac{1}{M}}

or,

(\frac{R_1}{R_2})=\sqrt{\frac{M_2}{M_1}}       ..........(1)

where,

R_1 = rate of effusion of nitrogen gas = 79mL/s

R_2 = rate of effusion of sulfur dioxide gas = ?

M_1 = molar mass of nitrogen gas  = 28 g/mole

M_2 = molar mass of sulfur dioxide gas = 64 g/mole

Now put all the given values in the above formula 1, we get:

(\frac{79mL/s}{R_2})=\sqrt{\frac{64g/mole}{28g/mole}}

R_2=52mL/s

Therefore, the rate of effusion of sulfur dioxide gas is 52 mL/s.

Which process releases energy that eventually produces lightning in the thunderstorm?
Ira Lisetskai [31]

Answer:

Answer: B. Water condenses to form clouds.

Explanation:

When the moisture condenses, this results in the release of energy. The energy causes the air to be warm and results in the rise of air in the upper atmosphere. This process results in the instability in the atmosphere and cumulonimbus clouds are formed. These clouds support lightening during a thunderstorm.

Determine the number of grams of sodium carbonate needed to prepare 100.0 ml of a 2.5 m solution
SCORPION-xisa [38]

Answer:

26.5 g

Explanation:

First we convert 100.0 mL to L:

  • 100.0 mL / 1000 = 0.100 L

Now we <u>calculate how many moles of sodium carbonate are needed</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • moles = molarity * liters
  • 2.5 M * 0.100 L = 0.25 mol

Finally we <u>convert 0.25 moles of sodium carbonate into grams</u>, using its <em>molar mass</em>:

  • 0.25 mol * 106 g/mol = 26.5 g

The rate constant for this first‑order reaction is 0.550 s−10.550 s−1 at 400 ∘C.400 ∘C. A⟶products A⟶products How long, in secon
Alisiya [41]

Answer:

t=2.08s

Explanation:

Hello,

In this case, for first order reactions, we can use the following integrated rate law:

ln(\frac{[A]}{[A]_0} )=kt

Thus, we compute the time as shown below:

t=-\frac{ln(\frac{[A]}{[A]_0} )}{k}=- \frac{ln(\frac{0.220M}{0.690M} )}{0.55s^{-1}} \\\\t=-\frac{-1.14}{0.550s^{-1}}\\ \\t=2.08s

Best regards.
