Answer: The correct option is Current W flows at a higher rate than Current Z.
Explanation: To answer this question, we will require Ohm's law.
Ohm's Law states that the current flowing through a conductor across two points is directly proportional to the voltage difference across that two points.
Mathematically,

where, V = voltage
I = Current
R = resistance
For the given question, assuming that the resistance is constant. So, the current is directly proportional to the voltage.

Hence, as the current W is greater of all the given currents so, it will flow at a higher rate.
Therefore, the correct answer is Current W flows at a higher rate than Current Z.
This is a two step step reaction as shown below,
Step 1: Epoxidation of Alkene: In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.
Step 2: Nucleophillic Substitution Reaction: In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
Answer: 2 kg/L or 2 g/mL
Explanation:
litres are a cubic measure. “Cubic litres” is redundant at best, potentially confusing.
I am pretty sure it is the most reactive elements
Typically the solvent used for the chromatography is rather volatile. So, its likely that the entire solvent will evaporate prior to the completion of the chromatography if the container isn't covered.
