a.NH₃+HCl⇒NH₄Cl
b.volume HCl=150 ml
c. pH=4.82
<h3>Further explanation</h3>
Reaction
NH₃+HCl⇒NH₄Cl
The equivalence point⇒mol NH₃=HCl
Titration formula :
M₁V₁n₁=M₂V₂n₂(n=acid base valence, NH₃=HCl=1)
mol NH₃
mol HCl=75 mlmol
Volume total :
mol NH₄Cl=mol NH₃=75 mlmol=0.075 mol
Dissociation of NH₄Cl at water to find [H₃O⁺]
ICE at equilibrium :
0.41-x x x
Ka(Kw:Kb)= 10⁻¹⁴ : 1.8.10⁻⁵=5.6.10⁻¹⁰
[H₃O⁺]=x :
pH=-log[H₃O⁺]

I think the correct answer is decrease in temperature
I feel like that’s the right one
They want to know if we can colonize Mars since Earth's resources are being more and more limited.
Answer:
Option (D) freezing point depression
Explanation:
Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.
