What are the answer choices ?
Answer:
the tilt in the Earth's axis causes seasons to change
Answer:
The amount of water on the Earth is constant, or nearly so. Actually, the amount is increasing ever so slightly due to volcanic eruptions expelling water vapor into the atmosphere, but, for all practical purposes, the amount of water (as a gas, liquid and as snow and ice) can be considered to be constant.
Explanation:
Answer:
and
are hydrogen boding,
and
are ion-dipole forces.
Explanation: If the bond is formed between a metal and a non metal then it is known as ionic bond and ionic compounds have positive and negative ions and so they have ion-dipole forces. Aluminium chloride and Iron(III)bromide both are ionic as they have a bond between a metal and non metal and so both of these have ion-dipole forces.
Ammonia and ethanol both are polar molecules and we know that polar molecules have dipole-dipole forces.
A hydrogen bond could form if hydrogen is bonded with more electron negative atom(N, O or F).
In ammonia, H is bonded to N and in ethanol, H is bonded to O, so both of these molecules must have hydrogen bonding. Since hydrogen bond is stronger as compared to dipole - dipole forces, we will say that both ammonia and ethanol have hydrogen bonding.
