<span>Water is known as a polar molecule because the oxygen atom has a greater attraction for electrons than the hydrogen atom does. Oxygen is more electronegative than that of hydrogen creating a partial charges with the hydrogen and oxygen atoms. Also, the electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms making it polar.</span>
I believe it is "The temperature of the ice sheet will be lowered" because it will most likely lower just a bit due to the heat. It's not going to fully melt but it will lower just a bit.
Plus I like your profile pic.

Answer:
Explanation:
<u>1) Determine the molar mass of the heptane</u>
element # of atoms atomic mass total mass
C 7 12.011 g/mol 7×12.011 g/mol = 84.077 g/mol
H 16 1.008 g/mol 16×1.008 g/mol = 16.128 g/mol
-------------------
Molar mass = 100.205 g/mol
<u>2) Percent of carbon, %</u>
- % = (mass of element / molar mass )×100
= (84.077 g/mol / 100.205 g/mol )×100 = 83.83 %
- Round to two significant figures: 84% ← answer
Water can be decomposed with electrolysis. Which gives you oxygen and hydrogen with their separate types of atoms.
