One of the researchers proposes using oxygen gas production to measure reaction rates. Which of the following statements best justifies the use of the proposed modification as a way of creating an appropriate control for the investigation?.

Answers

Answer 1

There are different factors taken into consideration in production process. The statement that best justifies the use of the proposed modification as a way of creating an appropriate control for the investigation is that;

The experiment can be repeated without the use of guaiacol, which will therefore show the effect of guaiacol on the reaction rates.

Oxygen is an element that exist naturally and can also be produced from different kinds of materials. This is often done by using a lot of different methods.

The natural method of getting oxygen is through photosynthesis where plants are known to use sunlight to convert carbon dioxide in the air into oxygen.

By not using guaiacol again when repeating the same experiment, one can therefore know if the guaiacol in one or different ways affect the chemical reaction of the elements.

Answer 2

Answer:

C. The experiment can be repeated without guaiacol, which will reveal the effect of guaiacol on the reaction rates.

Explanation:

In the original experiment, the researchers used guaiacol as a reaction indicator. By using oxygen gas production to measure reaction rates, the researchers no longer need the guaiacol and can repeat the experiment without it, which will reveal the effect of guaiacol on the reaction rates.

Answers

TIMESTAMPS

A timestamp is an indication (also called a marker) which tells us at what time / when the relevant text was spoken. They are represented in the format [HH:MM:SS]; where HH are hours, MM are minutes, and SS are seconds - from the beginning of the audio or video file.

There are different kinds of timestamps as below:

1. Periodic timestamps - Periodic timestamps appear at a consistent frequency. They can appear for every 15 seconds, 30 seconds, 1 minute, or 2 minutes.

2. Paragraph timestamps

3. Sentence timestamps

4. Speaker timestamps

Time stamping format used while transcribing audio files is:

[00:00:00]    

where [hour:minute:second]

so 5th minute is [00:05:00]

If the 5 - 15 minute part of an audio has to be transcribed stamping should be started at [00:05:00]

If a client requests time stamping every 30 seconds the next timestamp would be [00:05:30]

Which statement describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table?.

Answers

The statement that describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table is; The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.

The electronic configuration of arsenic is given as; 1s² 2s² 2p^(6) 3s² 3p^(6) 4s² 3d^(10) 4p³.

Now we can see that in that electronic configuration the orbitals are, s, p and D.

Now, the maximum electrons for each of the 3 orbitals are;

Maximum electrons for d orbital = 10 electrons

Maximum electrons for s orbital = 2 electrons

Maximum electrons for p orbital = 6 electrons.

Now, when we compare the maximum number of electrons for each orbital to the ones in electron configuration of arsenic, it is clear from the last 3 orbitals that the 3d and 4s orbitals are completely filled while the 4p orbital is half filled or partially filled.

Which sentence from Mark Twain's essay "Advice to Youth" conveys Twain's opinion about why one’s youth is the right time to learn good values?
Being told I would be expected to talk here, I inquired what sort of talk I ought to make. They said it should be something suitable to youth--something didactic, instructive, or something in the nature of good advice. Very well. I have a few things in my mind which I have often longed to say for the instruction of the young; for it is in one’s tender early years that such things will best take root and be most enduring and most valuable. First, then. I will say to you my young friends--and I say it beseechingly, urgingly-- Always obey your parents, when they are present. This is the best policy in the long run, because if you don't, they will make you. Most parents think they know better than you do, and you can generally make more by humoring that superstition than you can by acting on your own better judgment.

Be respectful to your superiors, if you have any, also to strangers, and sometimes to others. If a person offend you, and you are in doubt as to whether it was intentional or not, do not resort to extreme measures; simply watch your chance and hit him with a brick. That will be sufficient. If you shall find that he had not intended any offense, come out frankly and confess yourself in the wrong when you struck him; acknowledge it like a man and say you didn't mean to. Yes, always avoid violence; in this age of charity and kindliness, the time has gone by for such things. Leave dynamite to the low and unrefined.

a player pays $15 to play a game in which a chip is randomly selected from a bag of chips. the bag contains 10 red chips, 4 blue chips, and 6 yellow chips. the player wins $5 if a red chip is selected, $10 if a blue chip is selected, and $20 if a yellow chip is selected. let the random variable x represent the amount won from the selection of the chip, and let the random variable w represent the total amount won, where w=x−15. what is the mean of w ?

Answers

The mean of w which represents the total amount won where w = x + 15 is;

w = -$4.5

We are given;

Winnings if a red chip is selected; x₁ = $5.

Now, there are 10 red chips in a bag of 20 chips.

Thus, the probability of this outcome is:

p₁ = 10/20

p₁ = 1/2

Winnings if a blue chip is selected; x₂ = $10

Now, there are 4 blue chips in a bag of 20 chips.

Thus, the probability of this outcome is:

p₂ = 4/20

p₂ = 1/5

Winnings if a yellow chip is selected; x₃ = $20

Now, there are 6 blue chips in a bag of 20 chips.

Thus, the probability of this outcome is:

p₃ = 6/20

p₃ = 3/10

Finally, the expected value is:

E(X) = 5(¹/₂) + 10(¹/₅) + 20(³/₁₀)

E(X) = $10.5

We are told that w = x - 15

where x is the amount won from selection of chip which is E(X) = $10.5

Thus;

w = 10.5 - 15
