answer is: O
o goes from 0 to -2, so it is the element that is reduced
hope this helps! ;)
D electrons
a bond is not a physical material, it's an action
protons and neutrons are specific to that atom, and the amount doesn't change.
when atoms bond together, they share electrons to make themselves neutral
Answer: The average kinetic energy of water at
is
.
Explanation:
Given: Temperature = 
Kinetic energy is the energy acquired by the molecules of a substance due to its motion.
Formula to calculate average kinetic energy is as follows.

where,
T = temperature
k = Boltzmann constant = 
Substitute the value into above formula as follows.

Thus, we can conclude that the average kinetic energy of water at
is
.
The best way to know which is hemiacetal, acetal or other is by having in mind that Hemiacetals are compounds that are derived from aldehydes and ketones while acetals are compounds with a central carbon atom with 4 bonds attached to it. It must be saturated and has a tetrahedral geometry. I know with this you will get the answer
