Heat the solvent/solution with the solute over a Bunsen burner whilst mixing it with a glass storing rod or break up the solid into a powder to increase its surface area and then mix it with the solvent/solution.
Answer:
(C) substance B is not involved in the rate-determining step of the mechanism but is involved in subsequent steps.
Explanation:
A. Is incorrect because if the order of the reaction with respect B was one then the rate would increase by the same multiple that B is increased by.
B. If B is reactant then it must be involved in the mechanism of the reaction and in the formation of the product
D. If B was a catalyst then increasing it's amount would affect the rate
E. That is just factually untrue. Effect of reactants on rates can only be found experimentally, not stoichiometrically.
To know the answer to this problem, you can search online or in any textbooks for the chemical formula of quinine. This is essential because you can detect from the chemical formula the number of hydrogen atoms.
Quinine has the chemical formula C₂₀H₂₄N₂O₂. So, the ratio of hydrogen to quinine is 24/1.
<em>Moles of hydrogen = 1.1 mol quinine * 24/1 = 26.4 mol</em>
Since the bell weighs 190 N and is 45 m high, the bell’s potential energy is 8550 J
To answer the question, we need to know what potential energy is.
<h3>What is potential energy?</h3>
This is energy due to position. It is given by PE = mgh where
- m = mass,
- g = acceleration due to gravity and
- h = height of object.
Also, W = mg = weight of object.
So, PE = Wh
<h3>
The bell's potential energy</h3>
Now, given that the bells weight 190 N and is 45 m high,
So, PE = Wh
= 190 N × 45 m
= 8550 Nm
= 8550 J
So, the bell’s potential energy is 8550 J
