C is correct. right now gravity holds the atmosphere so if there is no gravity then no atmospher
Answer:
0.083 moles KCl
Explanation:
We have 252 mL of 0.33 M KCl. "M" is molarity, and it's measured in mol/L. Since we know the molarity is 0.33 mol/L, in order to find how many moles 252 mL is, we need to multiply our given volume by the molarity.
However, our given volume is in mL, so let's convert to L first by dividing 252 by 1000 (because there are 1000 mL in 1 L):
252/1000 = 0.252 L
Now, we can multiply 0.252 L by 0.33 mol/L to get moles since the L units will cancel out:
0.252 L * 0.33 mol/L = 0.08316
We have two significant figures here, so round 0.08316 to 0.083.
The answer is 0.083 moles.
Hope this helps!

Atoms share electons to reach 8 valence electons. these are covalent bonds
Many, srsly alot. can see in the periodic table. group 1 elements can become ions withs +1 charge while group 12 elements can become ions with -2charge
