Answer:

Matching the reaction on the top with the corresponding reaction on the left:

Explanation:

A) 2Na(s) + 2H2O(l) = 2NaOH(aq) + H2(g)

is Electrolysis breaks down water to form hydrogen and oxygen gas

B) 2H2(g) + O2(g) = 2H2O(g)

A bright light is produced when magnesium reacts with the oxygen in air to form magnesium oxide

What is the maximum number of grams of N-acetyl-p-toluidine can be prepared from 70. milliliters of 0.167 M p-toluidine hydrochl

Genrish500 [490]

Answer: The maximum amount of N-acetyl-p-toluidine that can be prepared is 1.7 grams.

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$

Molarity of p-toluidine hydrochloride solution = 0.167 M

Volume of solution = 70. mL

Putting values in above equation, we get:

$0.167M=\frac{\text{Moles of p-toluidine hydrochloride}\times 1000}{70}\\\\\text{Moles of p-toluidine hydrochloride}=\frac{0.167\times 70}{1000}=0.0117mol$
