You prepare a 2nd solution (solution B) by pipetting 10.00 ml of your 1st solution (solution A) into a 50.00 ml volumetric flask

and diluting with deionized water to the 50.00 ml mark.
If the concentration of solution B is 0.1045 M NaCl, what was the NaCl concentration of solution A?

Answer:

Concentration solution A was 0.5225 M

Explanation:

10.00 mL of solution A was diluted to 50.00 mL and yields 50.00 mL of solution B

According to laws of dilution-      C_{A}V_{A}=C_{B}V_{B}

where, C_{A} and C_{B} are concentration of solution A and B respectively

V_{A} and V_{B} are volumes of solution A and B respectively

Here C_{B} = 0.1045 M, V_{B} = 50.00 mL and V_{A} = 10.00 mL

Hence, C_{A}=\frac{C_{B}V_{B}}{V_{A}}=\frac{(0.1045M\times 50.00mL)}{10.00mL}=0.5225M

So, concentration solution A was 0.5225 M

Heating carvone with aqueous sulfuric acid converts it into carvacrol. The mechanism involves the following steps:
Fittoniya [83]

Answer:

See figure 1

Explanation:

In this question, we have to start with the <u>protonation of the double bond</u>. In carvone we have two double bonds, so, we have to decide first which one would be protonated.

The problem states that the <u>terminal alkene</u> is the one that would is protonated. Therefore, we have to do the <u>protonation</u> in the double bond at the bottom to produce the <u>carbocation number 1</u>. Then, a hydride shift takes place to produce the <u>carbocation number 2</u>. A continuation, an <u>elimination reaction</u> takes place to produce the <u>conjugated diene</u>. Then the diene is protonated at the <u>carbonyl group</u> and with an elimination reaction of an hydrogen in the <u>alpha carbon</u> we can obtain <u>carvacol. </u>
