It took 22 seconds for a sample of neon gas to effuse from a container About how long would it take for a similar sample of argon to effuse?
Remember that r1/r2 is INVERSELY PROPORTIONAL!!!!! to the square root of M2/M1, therefore if you square both sides you end up with 5625/23409 for you r1/r2 and x/20.18 for you M2/M1 no to solve you x you again have to remember that this is INVERSELY PROPORTIONAL!!!! meaning that M2 isn't (5625/23409)*20.18, instead its (23409/5625)*20.18 which equals 83.9 which should give you the answer of Kr.

How do you collect a mid-stream urine?
To collect a mid-stream urine sample, start by washing your hands thoroughly. Then, begin urinating into the toilet or a clean container without stopping. After a few seconds, carefully collect about 30-60 milliliters of urine in a sterile container. Make sure to avoid touching the inside of the container or the lid to maintain its sterility.
Why should you take care not to contaminate the outside of the sample container?
Contaminating the outside of the sample container can introduce external substances that may interfere with the analysis or lead to inaccurate results. It can also compromise the integrity of the sample or cause cross-contamination with other samples. Maintaining a clean exterior of the container ensures the purity and reliability of the sample being tested.
The pressure of a sample of helium in a 1.00 L container is 0.988 ATM What is the new pressure if the sample is placed in a 4.40 L container?
The pressure of the helium will decrease when placed in the larger container, following Boyle's Law. Using the formula P1V1 = P2V2, we can calculate the new pressure. So, (0.988 ATM)(1.00 L) = P2(4.40 L), which gives P2 = 0.225 ATM.
A sample of water was found to boil at 15C in a closed container What must have been true for this to occur?
The pressure must have been extremely low in the container.
How is the density of a small solid sample whose mass and volume is difficult to measure is determined?
Use a container with a liquid (water). Mark the level of the liquid on the container. Insert the small solid sample. Mark the level of the liquid now on the container. compute the difference between the two marks. You can use traditional computation for calculating volume.
How do you get a sample on critter forge?
use a sample container and drag it to the critter to take in a sample.You can also buy a sample in the auction.Sometimes it does not work when you drag it to a critter as each container only has a certain percentage of success.

When nitrogen gas is added to a sample of neon gas in a closed container the pressure inside the container?
increases
How to collect a stool sample for a vet from a cat?
To collect a stool sample from a cat for a vet, you can use a clean disposable container or a plastic bag to catch the sample. Make sure the sample is fresh and not mixed with litter. You can also use a special litter that does not clump to collect the sample. Store the sample in a sealed container and refrigerate it if you cannot bring it to the vet immediately.

If it has similar characteristics as the population the sample is termed?
It is called a representative sample.
How to collect a cat stool sample for testing?
To collect a cat stool sample for testing, use a clean disposable container or a plastic bag to collect a fresh sample. Wear gloves and avoid touching the stool directly. Store the sample in a sealed container and refrigerate it if not testing immediately. Transport the sample to the vet clinic as soon as possible for analysis.
How are biased and unbiased sample similar?
They are samples from a population, but otherwise they are not similar.
What fraction of a sample of N 16 remains undecayed after 43.2 seconds?
1.5% remains after 43.2 seconds.
A 200 gram sample having a half- life of 12 seconds would have how much remaining after 36 seconds?
To determine the remaining amount of a 200 gram sample after 36 seconds with a half-life of 12 seconds, we first calculate how many half-lives fit into 36 seconds. There are three half-lives in 36 seconds (36 ÷ 12 = 3). Each half-life reduces the sample by half: after the first half-life, 100 grams remain; after the second, 50 grams; and after the third, 25 grams. Therefore, 25 grams of the sample would remain after 36 seconds.
What is the procedure for collecting a stool sample from a cat for veterinary analysis?
To collect a stool sample from a cat for veterinary analysis, you will need to use a clean container and a disposable glove. Wait for the cat to defecate, then use the glove to pick up a small sample of the stool and place it in the container. Make sure to label the container with the cat's name and the date, and refrigerate it if you cannot bring it to the vet immediately.
