The pH of the solution is 0.37.
<h3>What is the pH of the solution?</h3>We can write the equation of the reaction as;
Number of moles of = 24/1000 * 1 = 0.024 moles
Number of moles of = 60/1000 * 1 = 0.060 moles
Given that the reaction is 1:1, the limiting reactant is NaOH
Number of moles of NH4Cl left over = 0.060 - 0.024 = 0.036 moles
Concentration of left over NH4Cl = 0.036 moles/(24 + 60)/1000
= 0.43 moles
pH = -log(0.43)
pH = 0.37

Answer:
When he weight of the car is 8.55 x N then power = 314.012 KW
When he weight of the car is 1.10 x N then power = 43.76 KW
Explanation:
Given that
Initial velocity = 0
Final velocity = 24.8
Time = 7.88 sec
We know that power required to accelerate the car is given by
P =
Change in kinetic energy Δ K.E =
Since Initial velocity = 0
⇒ Δ K.E =
⇒ Power P =
⇒ Power P = -------- (1)
(a). The weight of the car is 8.55 x N = 8550 N
Put all the values in above formula
So power P =
P = 314.012 KW
(b). The weight of the car is 1.10 x N = 11000 N
Put all the values in equation (1) we get
P =
P = 43.76 KW
