Answer:

C. All parts of Earth experience periods of daylight and darkness.

Explanation:

Not all parts of earth experience the same temperatures. For example, Alaska vs. Florida. Alaska is always freezing cold and Florida is generally always warm.

Not all parts of Earth experience extreme temperature changes either. For example, Florida doesn't experience extreme colds and Alaska doesn't experience extreme warmth.

Not all parts of Earth Experience the same amount of day and night. There are month long periods where Alaska doesn't see the sun, and it is pitch black, and dark. Florida experiences a decent amount of daylight. etc.

I used the same states for example throughout my answer to try to not confuse people. I hope my answer helped!

How many moles is ( 1 x 10^9 ) molecules O2
Effectus [21]

Answer:

The answer is

1.66 \times  {10}^{ - 15}  \:  \: moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}   \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{1 \times  {10}^{9} }{6.02 \times  {10}^{23} }  \\

We have the final answer as

1.66 \times  {10}^{ - 15}  \:  \: moles

Hope this helps you

3Pb2+(aq) + 2Cr(s) → 3Pb(s) + 2Cr3+(aq) What is the number of moles of electrons gained by 3.0 moles of lead ions?
Setler [38]
To determine the electrons gained in this redox reaction, we must balance the charges on the side containing the reduced substance and the side with oxidized substance. In this case, the reduced substance is Pb2+ and the oxidized substance is Cr. In each side, 6 electrons are gained or lose to balance the charges. The answer is 6 electrons.
