You are on an alien planet where the names for substances and the units of measures are very unfamiliar. Nonetheless, you obtain

40 quibs of a substance called skvarnick. You can trade this skvarnick for gold coins, but the vendors all measure skvarnick in units of sleps; not quibs. 15 quibs is equal to 13 sleps. If you have 40 quibs of skvarnick, how many sleps do you have? Round your answer to the nearest tenth (one decimal place). Type only the number; not the number and unit. Your Answer:

0.0625 mol of an ideal gas is contained within a 1.0000 Lvolume container. Its pressure is 142,868 Pa and temperature is X K . W
aliya0001 [1]

<u>Answer:</u> The temperature of the ideal gas is 2.75\times 10^2K

<u>Explanation:</u>

To calculate the temperature, we use the equation given by ideal gas equation:

PV=nRT

where,

P = Pressure of the gas = 142,868 Pa = 142.868 kPa    (Conversion factor: 1 kPa = 1000 Pa)  

V = Volume of gas = 1.0000 L

n = number of moles of ideal gas = 0.0625 moles

R = Gas constant = 8.31\text{L kPa }mol^{-1}K^{-1}

T = temperature of the gas = ?

Putting values in above equation, we get:

142.868kPa\times 1.0000=0.0625mol\times 8.31\text{L kPa }mol^{-1}K^{-1}\times T\\\\T=275K=2.75\times 10^2K

Hence, the temperature of the ideal gas is 2.75\times 10^2K

1. 5 ethyl, 2 methyl octane
2. 1 ethyl, 2 methyl cyclopentane
3. 3,3,5,5- tetrafluoro heptane
4. 3,4-dimethyl hexene
5. 3,4-dimethyl cyclobutene
6. 3,5 diisopropyl cyclohexene
7. 3,3,4 trimethyl pentyne
8. 2,6 dibromo phenol

keep in mind that between 4-7, there could be #1 in front of the main name. for example with #4: 3,4-dimethyl-1- hexene. this honestly depends on the professor how he/she likes it. It is not necessary because if the number is not specified, it is assumed is #1

You have at your disposal 3 1-pound bags of various pure salts that dissolve readily in water. You can add one of the bags to a
Sedaia [141]

Answer:

This question appears incomplete

Explanation:

However, it should be noted that addition of soluble salts generally lowers the freezing point of water hence after the addition, water will no longer freeze at 0°C but lower.

Soluble salts tend to form more ions in water, it is these ions that are responsible for interfering with the hydrogen bonds hence lowering the freezing. Thus, (since each bag are of the same weight) <u>the bag that contains the salt that ionizes more in water will lower the freezing point by the greatest amount</u>.

NOTE: Different weight of the salts could lead to more ions been formed in the water by some salts as against the other.
