Balloons may contain tiny microscopic holes, which allow the gas particles within to escape via effusion. Suppose a 4.30 L ballo

on is filled with 1.21 g of He to a pressure of 1.68 atm. A second balloon is filled with 39.63 g of Xe to the same volume and pressure. From which balloon will atoms effuse more quickly?

Explanation:

It is known that according to Graham's law of effusion of gases.

              \frac{R_{1}}{R_{2}} = \sqrt{\frac{M_{2}}{M_{1}}}

where, R_{1} = rate of effusion of gas 1 = rate of effusion of He

             R_{2} = rate of effusion of gas 2 = rate of effusion of Xe

            M_{1} = molar mass of gas 1 = molar mass He = 4.0026 g/mol

            M_{2} = molar mass of gas 2 = molar mass Xe = 131.29 g/mol

Now, we will substitute the values into the above formula as follows.

           \frac{R_{He}}{R_{Xe}} = \sqrt{\frac{M_{Xe}}{M_{He}}

                    = \sqrt{\frac{131.29 g/mol}{4.0026 g/mol}}

                    = \sqrt{32.8}

                    = 5.73

Thus, we can conclude that helium effuses 5.73 times faster than Xenon.

Answer:

The balloon filled with Helium will effuse more quickly.

Explanation:

Step 1: Data given

Balloon 1: Has a volume 4.3L , a pressure of 1.68 atm and is filled with 1.21g of Helium

Balloon 2: Has also a volume of 4.3 L and a pressure of 1.68 atm but is filled with 39.63 grams of Xenon

Molar mass of He = 4g/mol

Molar mass of Xe = 131.3 g/mol

Since He is lighter than Xe, the effusion rate for He will be larger than that for Xe, which means the time of effusion for He will be smaller than that for Xe.

The balloon filled with Helium will effuse more quickly.

What is the average velocity of atoms in 1.00 mol of argon (a monatomic gas) at 275 K? For m, use 0.0399 kg. (1 point)
valentinak56 [21]

What is the average velocity of atoms in 1.00 mol of argon (a monatomic gas) at 275 k for m, use 0.0399kg

Answer: The average velocity of the atoms 847.33 m/s.

Explanation:

Moles of the neon = 1.00

Temperature of the gas : 288 K

Mass of the gas = 0.01000

R = 8.31 J/mol K

The average velocity of the atoms 847.33 m/s.

You are given a solution of sugar and sand and water your task is to separate sugar from sand which of the following experimenta
Ostrovityanka [42]

Answer:

Explanation:

Filtration followed by evaporation:

To separate the mixture of sand and sugar, it is best to use the separation technique of filtration then evaporation.

Pour the water into the mixture. The sugar will dissolve with time in the water. Sand is made up of quartz and does not dissolve in water.

After the dissolution, filter the solution to separate the sand using a filter paper.

Dry the sand thereafter then proceed to evaporate the sugar with water solution. Evaporation will turn water into vapor and the sugar crystals will be left behind.
