33% of the total compound is SO2
A should be the answer because the more you test an experiment the more data you have to rely on changing the experiment would cause you to have different outcomes making the results different and unreliable so B, C, and D is not going to be the answer Hope this helps
<span>Answer:
Moles HgO = 10.36 g/ 216.59 g/mol= 0.048
the ratio between HgO and O2 is 2 : 1
moles O2 formed = 0.048/ 2= 0.024
at STP one mole of any gas occupies 22.4 L
Volume O2 = 0.024 x 22.4 L/mol = 0.54 L</span>
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:
Buffers are resistant to high pH changes.
Explanation:
This perfectly explains the reason why we use buffers. Buffers are substances which consist of a weak acid and its conjugate base. Buffers are resistant to significant pH changes upon addition of strong acids or bases. To illustrate this, let's say we have a buffer consisting of 0.1 mol of HF, a weak acid, and 0.1 mol of NaF (fluoride is a conjugate base of HF).
- Let's say we add some strong acid, in a general form, this acid would be represented as . In this case, conjugate base will react and neutralize it to produce some amount of HF: .
- Similarly, if we add some strong base , the acidic component will react with it to produce some amount of conjugate base: . The ratio of HF to NaF in this case is held around the same value for addition of small amounts of strong acids/bases, so pH is kept almost constant, while in neutral water, pH would drastically increase or decrease.
