Moles 
neutralized = moles 
neutralized at the equivalence point of a titration. Hence, option A is correct.

What is titration?</h3>
A method or process of determining the concentration of a dissolved substance in terms of the smallest amount of reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution.
Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution.
At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.
Hence, option A is correct.

Answer:
Explanation:
S is in 3d period, so it has 3 levels
1 level has 2 electrons, 2d level 8 electrons, 3d level 6 electrons
Answer:
Paraffin > Heptadecane > Hexane > 2,2-dimethylbutane > Propane
Explanation:
It must first be establish that all the molecules listed in the question are alkanes. For alkanes, the intermolecular forces between the molecules of alkanes increases with increasing molecular weight. This is as a result of increase in the surface area of the molecule. Increase in surface area implies a greater degree of dispersion forces.
This is the reason why high boiling points are observed for high molecular weight alkanes.
Body temperature is controlled by a negative feedback control system.
What is negative feedback?
In biological systems, a type of control known as negative feedback occurs when a process's output lowers its own stimulus. A common regulation mechanism in many biological responses is feedback. The body may regulate numerous aspects of its internal environment by permitting particular routes to be switched on and off. This is like turning a switch. Feedback enables a pathway's output to operate a switch. Negative feedback, often known as a "negative feedback loop," happens when a pathway's end product disables the corresponding metabolic step.
In order to maintain body temperature, the hypothalamus reacts to this information by directing nerve impulses to effectors. For instance, the hair erector muscles tighten up if we get too cold. As a result, a layer of air is trapped near to the skin, raising the skin hairs. Systematic negative feedback regulates body temperature.
<u>Thus the </u><u>hypothalamus</u><u> is the vital organ for this system.</u>
