Answer:
Explanation:
Hello,
In this case, for the computation of the energy loss when the cooling process is carried out, we use the shown below equation:
Whereas we need the mass, specific heat and change in temperature of iron within the process. Thus, the only value we need is the specific heat that is 0.444 J/(g°C), therefore, we compute the heat loss:
Negative sign points out the loss due to the cooling.
Regards.
Answer:
D) sodium t-butoxide + bromomethane
Explanation:
The alkoxide ion is a strong nucleophile, that unlike alcohols, will react with primary alkyl halides to form ether. This general reaction is known as <em>the Williamson synthesis</em>, and is a SN₂ displacement. The alkyl halide must be primary so the back side attack is not hindered, and the alkoxide ion must be formed with the most hindered group.
The mechanism can be seen in the attachment.
Answer:
F = 0.0725 N
Explanation:
Given that,
The mass of peach, m = 7.4 g
We need to find the force acts on the peach when it falls from a tree. The force is given by :
F = mg
So,
So, the force is 0.0725 N.
