Answer:
5-chloro-1,3-cyclopentadiene
Explanation:
5-chloro-1,3-cyclopentadiene will react more slowly in an SN1 reaction. ( i.e. No reaction as the product is unstable ) attached is the representation of the rate of reaction of both Halides which shows that 5-chloro-1,3-cyclopentadiene reacts the slowest .
Also During SN1 reaction Carbocation is formed .
Attached below is the solution explanation

<u>Answer:</u> The age of the mineral sample is
<u>Explanation:</u>
The equation used to calculate rate constant from given half life for first order kinetics:
where,
= half life of the reaction =
Putting values in above equation, we get:
We are given:
Mass ratio of K-40 to Ar-40 = 0.812 : 1.00
Rate law expression for first order kinetics is given by the equation:
where,
k = rate constant =
t = time taken for decay process = ? yr
= initial amount of the sample = [1.00 + 0.812] = 1.812 grams
[A] = amount left after decay process = 1.00 grams
Putting values in above equation, we get:
Hence, the age of the mineral sample is
Answer:
Explanation:
We can use the specific heat formula, which is:
Where <em>q</em> is the energy, <em>m</em> is the mass, <em>c</em> is the specific heat capacity, and ΔT is the change in temperature.
We know the mass is 250 grams. The specific heat capacity of water is 4.18 joules per gram degree Celsius. Let's find the change in temperature.
- ΔT = final temperature - initial temperature
Now we know all the values:
Substitute the known values into the formula.
Multiply the first 2 numbers together. The grams will cancel out.
Multiply again. This time the degrees Celsius will cancel out.
The energy needed is <u>80, 465 Joules.</u>
