We do not perform the titration while the sample is at its original temperature because reaction is too slow at original temperature and requires high activation energy.
A titration is a method where the concentration of an unknown solution is ascertained by comparing it to a solution of known concentration. The analyte (the unknown solution) is typically added in a known amount to the titrant (the known solution) from a buret until the reaction is finished.
The slow energy step in the reaction process may require a high activation energy, and the proportion of activated molecules needed to reach this reaction at room temperature or original temperature is too low, so most molecules cannot cross this peak. As a result, the reaction at room temperature proceeds very slowly (the final product is not reached). Heat can enhance the proportion of active molecules and catalyse a larger-scale reaction.

Answer:
32
Explanation:
There cannot be more in a number than the number. Therefore, the answer has to be D, or 32.
Hope this helps! :)
Neutrons and protons are in the nucleus
electrons are on shells which orbit the nucleus
The temperature of the air, pavement, and the type of ice-melt compound used will affect the rate at which the ice melts. There are many different ice-melt compounds available from traditional rock salt (sodium chloride) to ice-melt pellets (calcium chloride).
