If an unknown sample contains 39.04% sulfuric acid by mass, then a 0.9368 g of that sample would require _____ mL of 0.2389 M Na
bonufazy [111]

Answer:

A) 31.22

Explanation:

The reaction of sulfuric acid with NaOH is:

H₂SO₄ + 2 NaOH → Na₂SO₄ + 2H₂O

To solve this problem we need to determine the moles of acid that will react, and, using the chemical equation we can determine the moles of NaOH and the volume that a 0.2389M NaOH solution would require to neutralize it.

<em>Moles H₂SO₄ (Molar mass: 98.08g/mol):</em>

0.9368g * 39.04% = 0.3657g H₂SO₄ * (1mol / 98.08g) =

3.7289x10⁻³moles H₂SO₄

And moles of NaOH that you require to neutralize the acid are:

3.7289x10⁻³moles H₂SO₄ * (2 moles NaOH / 1 mole H₂SO₄) =

7.4578x10⁻³ moles NaOH

Using a 0.2389M NaOH solution:

7.4578x10⁻³ moles NaOH * (1L / 0.2389mol) = 0.03122L = 31.22mL

Right answer is:

<h3>A) 31.22 </h3>

Which of the newman structures below represents this conformation of 2-methyl-3-pentanol, as viewed along the c2-c3 bond?
castortr0y [4]

Answer:

(4) option is correct

Explanation:

Given that,

The conformation of 2-methyl-3-pentanol, as viewed along the C₂-C₃ bond.

We need to find the Newman structures

Using given structures

The structure of 2- methyl-3- pentanol is shown in figure.

Through C₂-C₃ carbon shown the structure of Newman projection in figure.

Here, carbon 2 is in front side and carbon 3 is in back side in the figure.

Hence, (4) option is correct.

The freezing point of diet soda is higher than the freezing point of regular soda, but lower than 0 degrees celcius, the freezin
Zepler [3.9K]

Answer:

Explanation:

Both Diet Soda and regular soda contain sweeteners.

When a solute is dissolved in solution, the solution undergoes *freezing point depression* it freezing point reduces. The magnitude of freezing point depression is directly proportional to the amount of solute in a solution.

Since soda Both regular or diet soda contains more solute than water , their freezing point is will consequently be lower than water
