To answer this, we look at the polarities of these molecules given. A molecule is said to be polar when there is an unequal shraing of electrons the opposite is called nonpolar.
CH4 = nonpolar
CH3OH = polar
CH3 CH3 = nonpolar
CH3 CH2 CH2 OH = polar
<span>CH3 CH2 CH2 CH2 CH2 CH3 = nonpolar</span>
the heat of reaction for a chemical reaction
Old wives tale
Explanation:
This is an old wives tale and not scientifically correct.
Water is liquid that is known to freeze at 0° C.
The boiling point of water is also 100° C.
- If the farmer sprays the cherries on the tree with water, it suggests that they will freeze faster because water has high freezing point compared to that of the cherry.
- This will not in any way protect the cherries on the tree.
- To prevent the cherries from freezing, he should spray them with something that has lower freezing point.
