Chemistry
1 answer:

3 0

P O₂ = 736.2 torr

<h3>Further explanation</h3>

Given

P tot=760 torr

P H₂O = 23.8 torr

Required

P gas/O₂

Solution

Dalton's law of partial pressures stated that

<em>the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases   </em>

Can be formulated:  

P tot = P1 + P2 + P3 ....  Pn

P tot = P H₂O + P O₂

760 torr = 23.8 torr + P O₂

P O₂ = 760 - 23.8

P O₂ = 736.2 torr

Lauren has a big social studies test coming up. She knows that she needs to spread out her study sessions over a period of time.
tatuchka [14]

The study strategy Lauren is using in spreading her study sessions over a period of time is pacing, which helps the student develop a schedule focused on their own study pace.

<h3>Pacing Study Sessions</h3>

This study strategy of distributing the study into short sessions rather than studying the entire content through one long session is more effective in retaining content and learning.

What happens is that Lauren is using mass repetition processing, which can be compared to a longitudinal wave in physics, with spaces in between, concentrating the initial review close to the proof to ensure retention and avoid forgetting.

Through pacing, Lauren achieves greater motivation to carry out her studies in a concentrated and focused way, helping her to retain and preserve knowledge.

The correct answer is:

  • Pacing

How long does it take for only one eighth of a sample of radon-222 to remain
Alex17521 [72]
1/8=(1/2)^3 and the half life of radon is 3.8days

Half life is the time it takes for half of any amount of a radioactive substance to decay into something else.

Therefore for a sample of radon to decay to 1/8 of its original amount, it would take 3 x 3.8days=11.4 days

Which conditions are necessary for natural selection? Check all that apply.
zepelin [54]

Answer:

Populations have genetic variation.

The environment changes.

Organisms must have specific traits in order to survive and reproduce.

Explanation:

Natural selection provides an advantage during an adverse condition for organisms that have a rich genetic variation in their population.

Also, environmental changes induced natural selection whereby organisms must adapt to changes around them.

For organisms to survive, they must have specific traits that gives them a competitive reproductive advantage.
