T or F: Lone pairs around the oxygen atom of a water molecule play no role in determining its molecular geometry?
Mama L [17]

Answer:

Explanation:

They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang. The two hydrogens and the 2 lone electron pairs try to get away as far as possible from each other. The actual shape results in a tetrahedron shape. But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.

How many grams are in 2 moles of H₂O?
Lynna [10]

<em>Question:</em>

<h2>How many grams are in 2 moles of H₂O?</h2><h2 />

<u><em>Answer:</em></u>

<h3>One mole of H2O has a mass of (2*1 + 1*16 = 18g). We read the 1 and the 16 from the periodic table of the elements under “atomic weight” or “atomic mass”. I’ve taken the whole numbers from memory to keep it simple but you can read a more accurate value if you need a more accurate value from your periodic table. </h3><h3 /><h3>So if one mole of H2O has a mass of 18g, then 2 moles will have a mass of 18*2 = 36g.</h3><h3 />

<em>Note: * I am not responsible if you get it wrong, for you are the one who asked the question. *</em>

<h3><em>⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯</em></h3>

<u>If this helped, your welcome! Please know that I might be wrong, and if I am, I am truly sorry for that. But If you would, please make me brainliest.</u>

I hope you have a rest of your great day! If there is an issue with this question, be happy to comment. <3
