Answer:
Aromatization leads to evolution of carbon dioxide
Explanation:
In p-hydroxybenzoic acid, -OH and -COOH groups remain in para position.
The directing effect of -OH and -COOH group act synergistically to react with three equivalent of bromine.
In para position of -OH group, -COOH remains attached along with a Br atom in a same carbon atom. During aromatization of benzene group, this -COOH group decomposes to give carbon dioxide.
Reaction scheme has been shown below.
number of protons, neutrons, and electrons for an atom of any element. Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral.
Hope I helped :)
The volume : V₁ = 1.29 ml
<h3>Further explanation</h3>
Given
V₂=450 ml
M₂=0.02
M₁=7.0
Required
V₂
Solution
Dilution is the process of adding solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
n₁=n₂
Dilution formula :
M₁V₁=M₂V₂
Input the value
V₁= (M₂V₂)/M₁
V₁ = (0.02 x 450)/7
V₁ = 1.29 ml
Answer:
<u>We are given:</u>
v1 = 3.2 L v2 = x L
p1 = 822 torr OR 1.08 atm p2 = 2.33 atm
t1 = t2 = 284 k
<u></u>
<u>From the Ideal gas equation:</u>
PV = nRT
Since the number of moles (n), universal gas constant (R) and Temperature (T) are constant
PV = k (where k is a constant)
it can also be written as:
P1V1 = k --------------------------(1)
Similarly,
P2V2 = k (where k is the same constant as before)----------(2)
<u>Solving for V2:</u>
From (1) and (2):
P1V1 = P2V2
Replacing the variables
1.08 * 3.2 = 2.33 * x
x = (1.08 * 3.2)/2.33
x = 1.5 L (approx)
Therefore, the final volume of the solution will be 1.5L
Answer:
100 cg/1g
Step-by-step explanation:
1 cg = 0.01 g Multiply by 100
100 cg = 1 g
(a) is <em>wrong</em>. The correct conversion factor is 1000 cm³/1 L.
(b) is <em>wrong</em>. The correct conversion factor is 1000 mL/1 L.
(c) is <em>wrong</em>. The correct conversion factor is 1 m/10 dm.
