A mixture of CO2 and Kr weighs 35.0 g and exerts a pressure of 0.708 atm in its container. Since Kr is expensive, you wish to re
ollegr [7]

Explanation:

Since, it is given that carbon dioxide is completely removed by absorption with NaOH. And, pressure inside the container is 0.250 atm.

For Kr = 0.250 atm and pressure CO_{2} will be calculated as follows.

           CO_{2} = (0.708 - 0.250) atm

                       = 0.458 atm

Now, we will calculate the mole fraction as follows.

            CO_{2} = \frac{0.458}{0.708}

                       = 0.646

               Kr = \frac{0.250}{0.708}

                    = 0.353

Now, we will convert into gram fraction as follows.

              CO_{2} = 0.646 \times 44

                          = 28.424

                   Kr = 0.353 \times 83.78

                        = 29.57

Therefore, total mass is calculated as follows.

           Total mass = (28.424 + 29.57)

                              = 57.994

Hence, the percentage of CO_{2} and Kr are calculated as follows.

          CO_{2} = \frac{28.424}{57.99} \times 100

                     = 49%

               Kr = \frac{29.57}{57.99} \times 100

                    = 51%

Hence, amount of CO_{2} and Kr present i mixture is as follows.  

         CO_{2} in mixture = 35 \times 0.49

                             = 17.15 g

                  Kr = 35 \times 0.51

                       = 17.85 g

Thus, we can conclude that 17.15 g of CO_{2} is originally present and 17.85 g of Kr is recovered.

 Water can dissolve other substances. Which factor best contributes to this property of water?
Sav [38]
<span>Water is known to be the universal solvent because it can mostly dissolve most of the substances. The reason behind its solvability is the bonding of intermolecular forces of attraction. The answer is letter B. Out of the many bondings between molecules, the bond that governs water is H bonding or hydrogen bonding. Water is composed mostly of two atoms of hydrogen one atom of oxygen. Both the hydrogen and oxygen are polar elements and hydrogen is bounded with a high electronegativity oxygen atom.</span>

Write a short note on LAN? Also write down its advantages and disadvantages of LAN?​
Artist 52 [7]
Area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus, or office building.

The advantages of local area network are:

• you can share resources
•you can share your software applications
• you can have easy and cheap communication
• you have centralized data
• you have data security
•you have Internet sharing

The disadvantages is a local area network are:

• high set up cost
• local area network administrators can see and check personal data files of each and every user
• Data security threats
• maintenance jobs
• covers limited areas
