Temperature of the same cup of water will rise by 6 °C unless it boils.
<h3>Explanation</h3>
.
However, neither 
nor 
is given.
Adding 
to this cup of water of mass rises its temperature by 
.
In other words,
.
Both and are constant for the same cup of water unless the water boils. It's possible to reuse the value of 
in the second calculation. Here's how:
.
HA and HB are present in concentrations of 0.182 M and 0.153 M, respectively.
<h3>What kind of acids are monoprotic?</h3>
Monoprotic acids include benzoic acid (C6H5CO2H), acetic acid (CH3CO2H or HOAc), nitric acid (HNO3), and hydrochloric acid (HCl).
<h3>How can you tell if a substance is monoprotic?</h3>
Any acid with only one hydrogen atom in its formula is called a monoprotic acid, while some acids with multiple hydrogen atoms may also fall under this category. In other words, while all monoprotic acids contain only one hydrogen, not all single-hydrogen acids are monoprotic.
<h3>Do monoprotic acids have a low acidity?</h3>
Because it easily loses its hydrogen ion in solution, the monoprotic acid HBr is regarded as being strong.

Answer:
See explanation and image attached
Explanation:
The reaction of (R)-2-chloro-3-methylbutane with potassium tert-butoxide yields a monosubstituted alkene .
Since the base is bulky, the Hoffman product predominates because attack occurs at the less hindered carbon atom to yield the major product as shown.
The alkene reacts with HBr at the secondary carbon atom to yield a carbocation intermediate which is flat and planar. Attack on either face of the carbocation yields a racemic mixture of the (2R) and (2S) products.
Rearrangement of the carbocation to yield a tertiary carbocation gives the 2-bromo-2-methyl butane product as shown in the image attached.
