Polar molecules exhibit an unequal balance of charges between the individual elements of the compound. This is brought about by the large difference in their electronegativities. The H atom has the least amount of electronegativity. Then, it is a known periodic trend, that as you go downwards in a group, electronegativity decreases, and increase as you go from left to right. Thus, you can deduce that the most electronegative elements are found in the upper right corner which includes O, N and F atoms. Any bond created between Hydrogen and any of O, N and F atoms is a polar bond.

Find the density of a substance with a mass of 45 grams and a volume of 9
Over [174]

Density = mass / volume

Density = (45g) / (9 [volume units])

Density = 5g / [volume unit]

There was no specification on the units of volume.  However, whatever it may be, just replace the square brackets with the value and your units will be correct.

PLS HELPPP<br> why is CH3OH more polar than CH3CH2OH
dusya [7]

Answer:

Explanation:

Polarity is about differencens in electronegativity. CH bonds have around the same electronegativity value so a CH bond is nonpolar. The more CH bonds there are in a molecule, the more nonpolar it is. Since CH3CH2OH has more carbon-hydrogen bonds than CH3OH, it is more nonpolar. With the same reasoning, since CH3OH has less CH bonds, it's more polar.

What is the natural and human factors that affect climate?
frozen [14]

Answer:

Some of the various things that humans do to the environment is pump CO2 into the air with Fossil Fuels and using Power Plants, Cutting down trees make more CO2 which can make the Earth hotter and cause Global Warming. Some natural things that can tend to affect climate can be changes in Volcanic activity, Solar activity with the sun, and Earth's orbit around the sun.

Explanation:

It may seem crazy how Earth's orbit around the sun make climate change, but how else would 4 seasons exist. The orbit tends to be in an oval shape. The top parts of the oval, would represent winter and fall because of the distance between the sun decreases. The closer sides of the oval however, would represent Summer and spring because those are the warmer months and show that Earth is closer to the sun.
