Explanation:
Explanation:
Both water and carbon dioxide have 2 bonding domains (with the 2 hydrogen atoms and 2 oxygen atoms respectively)
However, water is a polar molecule as the central oxygen atom has 2 pairs of lone electrons, which allows it to form hydrogen bonding with other water molecules.
Carbon dioxide on the other hand is non-polar because it has no lone pairs on the central carbon atom, allowing its molecular geometry to be linear.
Hence the answer is Option C.
Answer:
Incorrect
Explanation:
Given that,
The mass of a boulder, m = 22 kg
We need to find the weight of the student in pounds.
We know that,
1 pound = 454 g
or
1 g = (1/454 pounds)
22 kg = 0.022 grams
So,
0.022 grams = 
= 0.000048 pounds
The student says the weight is 0.048 pounds. It means he was incorrect.
