Answer:
a) 6,7x10⁻⁴M/s
b) 8,0x10⁻⁴M/s
Explanation:
a) You can determine the average rate of descomposition calculating the ratio of change of concentration to change of time.
For the entire experiment:
t=0,00→ 0,0100M
t=10,00→0,0033M
= 6,7x10⁻⁴M/s
b) Between 2,00 and 4,00 seconds:
t=2,00→ 0,0071M
t=4,00→0,0055M
= 8,0x10⁻⁴M/s
I hope it helps!
Benzyl Amine is synthesized from Toluene in two steps;
Step 1: Bromination of Methyl Group in Toluene: Bromination is carried out on methyl group present on Benzene ring through free radical mechanism by treating toluene with <span>N-Bromosuccinimide (NBS) and Benzyl Bromide is formed.
Step 2: Benzyl Bromide into Benzyl Amine; This step is carried out utilizing a neme reaction "Gabriel Reaction". Benzyl bromide is treated with </span>Potassium Phthalamide and an intermediate is formed which on treatment with Hydrazine produces Benzyl amine.
Answer:
The molar mass and atomic mass are essentially the same for an element
Explanation:
The molar mass of a substance can be obtained by dividing the mass of the substance by the no of moles of the substance present.
The atomic mass of an element is the number of protons and neutrons present in the substance.
These two measurements usually give the same values because they both make reference to the 1/12th the mass of carbon-12 for their measurement.
Because they both have the same reference point, though they have different calculating procedures, the results obtained will be similar.
Answer:
- line segment of length 8 between the vertices at (-1, -2) and (-1, 6)
Explanation:
The equation can be rearranged to standard form.
(y^2 -4y) -4(x^2 +2x) = 16
(y^2 -4y +4) -4(x^2 +2x +1) = 16 +4 -4
(y -2)^2 -4(x +1)^2 = 16
(y -2)^2 /16 -(x +1)^2/4 = 1
This is of the form ...
(y -k)^2/a^2 -(x -h)^2/b^2 = 1
where the transverse axis is 2a and the center is (h, k). Here, a=4, so 2a = 8.
The transverse axis is a vertical line segment of length 8, centered on (-1, 2).
1 mile = 1609 m
and 1 hour = 3600 seconds
so we can convert 1220 m/s into miles per hour as following:
(1220 m/s) ×( 3600 sec/hour) ÷ (1609 m/mile)
= 2729.65 mile/hour
