Answer: The Volume of NaOH required to neutralize

1) 25 mL of a 0.150M HCl solution is 25 mL

2) 55 mL of a 0.055M HCl solution is 20.2 mL

3) 175 mL of 0.885M HCl solution is 1032.5 mL

Explanation: Neutralization reactions are defined as the reactions when an acid reacts with a base to form a salt and water.

For the reaction of HCl and NaOH,

NaOH(aq.)+HCl(aq.)\rightarrow NaCl(aq.)+H_2O(l)

To calculate the molarity of NaOH, we use the formula:

M_{NaOH}\times V_{NaOH}=M_{HCl}\times V_{HCl}

1.) 25 mL of a 0.150M of HCl solution.

M_{NaOH}=0.150M;V_{HCl}=25mL;M_{HCl}=0.150M

Putting the values in above equation, we get

0.150\times V_{NaOH}=0.150\times 25\\V_{NaOH}=25mL

2.) 55 mL of a 0.055M of HCl solution.

M_{NaOH}=0.150M;V_{HCl}=55mL;M_{HCl}=0.055M

Putting the values in above equation, we get

0.150\times V_{NaOH}=0.055\times 55\\V_{NaOH}=20.2mL

3.) 175 mL of a 0.885M of HCl solution.

M_{NaOH}=0.150M;V_{HCl}=175mL;M_{HCl}=0.885M

Putting the values in above equation, we get

0.150\times V_{NaOH}=0.885\times 175\\V_{NaOH}=1032.5mL

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. One of
pochemuha

Answer:

1,4-dihydro = 113 kJ·mol⁻¹

1,2-dihydro = 101 kJ·mol⁻¹

Explanation:

In 1,4-dihydronaphthalene, the 2,3-double bond is isolated from the benzene ring.

In 1,2-dihydronaphthalene, the 3,4-double bond is conjugated with the benzene ring.

Thus, 1,2-dihydronaphthalene is partially stabilized by resonance interactions between the ring and the double bond (think, styrene).

1,2-Dihydronaphthalene is at a lower energy level because of this stabilization.

The heat of hydrogenation of 1,2-dihydronaphthalene is therefore less than that of the 1,4-isomer when each is hydrogenated to the common product, 1,2,3,4-tetrahydronaphthalene.

How much 2.0 M phenylmagnesium chloride solution is needed if adding 2.9 mmol of Grignard reagent to a reaction? Your answer sho
Vladimir [108]

Answer:

1,45 mL

Explanation:

The Grignard reaction is a very important organometallic chemical reaction where the Grignard reagent ( alkyl, vinyl, or aryl-magnesium halides) acts as nucleophile in order to the formation of Carbon-Carbon bonds.

In the problem, the phenylmagnesium chloride is the grignard reagent. The volume of 2.0 M phenylmagnesium chloride solution you need to add 2.9 mmol is:

2,9 mmol × \frac{1mL}{2,0mM} = <em>1,45 mL</em>

<em></em>

I hope it helps!
