The modern day model of an atom has a lot of questions answered about it answered and is very accurate while John's version was a very early model before technology was advanced enough to get more information on it so it was very basic and not as accurate as today's model. Hope this helps!

Which of the following you do NOT need to pay attention while using a centrifuge?
Phoenix [80]

Answer:

The radius of the centrifuge.

Explanation:

Hello,

Since the radius of the centrifuge is just a design parameter, it wouldn't be a cause of failure because it is used to know how many tubes could be fitted in into the centrifuge. On the other hand, keeping you attention away from other factors could turn into a failure as long as the sample could be poured down or just turn out inadequate for the expected results.

Best regards.

Entropy means that _________.A. the quantity of usable energy declines with each transformationB. energy can be neither created
son4ous [18]

Answer:

answer A

Explanation:

A) the quantity of usable energy declines with each transformation → True . Since the entropy increases , the amount of energy that can not be converted to useful energy increases and since the total amount of energy is conserved, the quantity of useful energy decreases.

B) energy can be neither created nor destroyed → False in the context of entropy , since the energy is conserved regardless of the changes in entropy (First law → conservation of energy vs second law → increase of entropy)

C)  life should be impossible → False . Since the second law states that the entropy of the <u>universe </u>increases with time . Then the system (life) can experience a decrease in entropy  at the expense of a larger increase in entropy of the surroundings ( so the net increase is positive)

D) it is not possible to observe an increase in molecular organisation → False . Same as C. A system  can experience a decrease in entropy at the expense of a larger increase in entropy of the surroundings ( so the net increase is positive)

Each astronaut produces 8.8 × 102 g CO2 per day that must be removed from the air on the shuttle. If a typical shuttle mission i
suter [353]

The reaction of removing CO2 using LiOH is the following:

2 LiOH + CO2 -----> Li2CO3 + H2O

By solving the amount of CO2 the LiOH can scrub:

(3.50 × 10^4 g LiOH) (1 mol LiOH/ 24 g LiOH) ( 1 mol CO2 / 2 mol LiOH) ( 44 g CO2 /1 mol CO2) = 32, 083.33 g CO2 it can scrub

<span>Since number of astronaut = 32, 083.33 g / 9 (8.8 × 10^2) = 4 astronaut</span>
