Answer:
Explanation:
Hello,
In this case, the change in the entropy, by knowing the change in the enthalpy and the temperature for a vaporization process is given by:
Thus, we start by computing the change in the enthalpy for the 3.3g of dichloromethane as shown below:
Finally, the change in the entropy, considering the temperature in kelvins:
Best regards.
Answer:
The equilibrium is shifted to the formation of OH⁻.
Explanation:
AH + OH⁻ ⇄ A⁻ + H₂O
At the equivalence point, the acid AH has entirely been converted to A⁻, which is its conjugated base. This causes the equilibrium to shif to consume the excess of A⁻, which leads to production of OH⁻. This is why, at the equivalence point, the pH is larger than 7.
It is a subscript
Also do you mean Cl not Ci. I assume you do because then it means 4 chlorine in that compound.
Correct Answer: Option a. 6150.64 N
Weight (w) is defined as:
w = mg
So, first we need to find the mass (m) of the steel block using its volume and density.
Mass = Density x Volume
So,
m = 0.08 x 7840 = 627.2 g
Using value of m and g = 9.807, we get
w = 627.2 x 9.807 = 6150.95 Newtons
Therefore, option a is the correct answer.
The slight difference is because the value of g is rounded of to 3 decimal cases.
