The balanced chemical equation representing the neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH),
This reaction is exothermic that is it proceeds by the release of heat energy. This heat energy is lost to the surroundings. This is the reason for the warming up of the beaker where the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) takes place. The enthalpy of such reaction will be negative as the reaction is exothermic.
Mass is the measure of the quantity of the substance present in the sample containing a compound or molecule. The mass of sucrose in the sample is 171 g.
<h3>What is mass?</h3>
The mass of the compound in the sample is the product of the number of moles of the substance and the molar mass of the compound.
Given,
The molar mass of the sucrose compound = 342.3 g/mol
Number of moles of sucrose = 0.500 moles
Mass of sucrose is calculated as:
Therefore, option A. 171 gm is the mass of sucrose.

What? That docent make any scene?
B is the answer to it!!!!!
Non-metal are the elements that can accept electrons,this creates a larger positive charge in the nucleus than the negative charge.
Due to this attraction, electron cloud shrinks or come closer to nucleus as the result of opposite charge and become ion .
Hence, the atomic radius of a non-metal<span> is generally smaller than the </span>ionic radius<span> of the same element.</span>
