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.

Explanation:
The above two reactions xcan also be written in form of single chemcial equation:
![FeCl_3+K(SCN)\rightleftharpoons KCl+[Fe(SCN)]Cl_2(blood-red)](https://tex.z-dn.net/?f=FeCl_3%2BK%28SCN%29%5Crightleftharpoons%20KCl%2B%5BFe%28SCN%29%5DCl_2%28blood-red%29)
1. Color of ferric chloride solution is yellow. This is due to presence of ferric ions which have yellow color in their aqueous solutions.
2. KSCN has the colorless solution. This due to potassium ion forms colorless aqueous solution.
3. On mixing, KSCN with 
we will get blood red color solution of ![[FeSCN]Cl_2](https://tex.z-dn.net/?f=%5BFeSCN%5DCl_2)
.

Answer:
True, gasses can apply a force on an object.
Answer:
c) neutrons and protons
Explanation:
The nucleus of the atom contains only neutrons and protons. Electrons are not in the nucleus but outside the nucleus in 'atomic orbitals'.
