A biomolecule with a hydroxyl (--oh) functional group is
given the polar chemical property since organic molecules with an OH group are
polar.
A part of a larger molecule is made up by a functional
group. The hydroxyl group (-OH) that characterizes alcohols, an oxygen with a
hydrogen attached, is an example of it. This group can be found on any number
of different molecules.
Functional groups have characteristic chemistries, just
as elements have unique properties., although perhaps not identically,
to an -OH on another molecule. Although perhaps not
identically to an -OH on another molecule, an -OH group on one molecule will tend to react similarly.

Answer:
3.66 moles of Zinc Oxide are consumed
Explanation:
Based on the reaction:
C + 2ZnO → 2Zn + CO₂
<em>Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.</em>
<em />
To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):
1.83 moles C * (2mol ZnO / 1mol C) =
<h3>3.66 moles of Zinc Oxide are consumed</h3>
Find the [OH-] in the solution. The pH is 9.5, so the pOH is 14 - 9.5 = 4.5.
[OH-] = 10^-4.5 M
Now use the dilution equation to find the new [OH-] after the volume is reduced from 150 mL to 50 mL:
M1V1 = M2V2
M1 = 10^-4.5 M
V1 = 150 mL
M2 = ?
V2 = 50 mL
(10^-4.5)(150) = M2(50)
M2 = 9.5 x 10^-5 M ≈ 1 • 10^-4 (We can only use one sig fig, because the pH was given to one decimal place.)
Now use this [OH-] to find pOH:
pOH = -log(1 x 10^-4) = 4.0
14 - pOH = pH, so the expected pH for the new solution is 10.

In the explanation
Explanation:
First of all, make sure you re-read the lesson carefully and memorize the definitions. pls
forces are push and pull.
And just give an example of like someone pushing a sofa into the living room (push).
Another example of pull is pulling a door knob to open a door.
And ANOTHER example can be pushing a tissue box or anything.
Forces can be balanced and unbalanced, that is correct.
When the netforce is equal to 0 then it is balanced, if not then it’s unbalanced.
Balanced which results a netforce equals to 0, there is no change in motion.
Unbalanced which causes in the object's motion changing (For example an tug of war, some guy pulls 10N to the right and the other person 5N to the left, obviously the netforce will be 5N to the right; Unbalanced force)
Last two boxes, maybe add examples as I mentioned? And add another example from ur textbook or something.
