The mass would still be the same 25.0 g but the volume would be bigger
Graphite and diamond are allotropes of carbon. Allotrophy is the existence of an element in more than one form but the same physical state. Carbon is an example of element that exhibits allotrophy; these are diamond and graphite; which differ in structure and chemical properties. Another element that exhibits allotrophy is sulfur; with monoclinic and rhombic sulfur.
The pH of the resulting solution is 2.82.
<h3>What is pH ?</h3>
pH is the measure of acidity and alkalinity of a solution , It has a range of 1 to 14.
HCl + NaOH → NaCl + H₂O
0.0040 .0025 0 0
0.0040 -0.0025 0 0.0025 0.0025
Moles of HCl = 0.0015
As 0.0025 moles of NaOH reacts with 0.0025 moles of HCl leaving behind 0.0015 moles of HCl
Concentration of HCl = 0.0015/ 1 = 0.0015 M
[ H⁺] = 0.0015 M
pH = -log [ H⁺]
pH = -log [ 0.0015]
pH = 2.82
Therefore the pH of the resulting solution is 2.82.

A Scottish scientist Graham, Thomas formulated Graham's law of effusion or simply Graham's law. This law states that rate of gas 1 over gas 2 is equal to the square root of the molar mass of gas 2 over <span>he square root of the molar mass of gas 1. Since the molar mass of Neon is 4, the answer is then 8.16 g/mol</span>
Cl has 7 valence electrons, it needs 8 to be stable, according to the octet rule, so Cl gains stability by gaining 1 electron to reach 8 electrons
