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!

Explanation:
Answer: The mass of
needed is, 13.59 grams.
Explanation : Given,
Mass of
= 89.2 g
Molar mass of
= 42 g/mol
Molar mass of
= 32 g/mol
First we have to calculate the moles of 


Now we have to calculate the moles of 
The balanced chemical equation is:

From the reaction, we conclude that
As, 1 mole of
react with 5 mole of 
So, 2.124 mole of
react with
mole of 
Now we have to calculate the mass of 


Therefore, the mass of
needed is, 13.59 grams.
