Sergio [31]3 years ago
8 0

Answer:

Electromagnetic waves

Explanation:

The description given is that of an electromagnetic wave.

Electromagnetic waves are propagated by the vibration of electrical and magnetic fields in a perpendicular direction to one another.

  • These waves generally travel at the speed of light.
  • They are made up of magnetic and electric fields.
  • They do no require a material medium for their propagation
  • They can pass through a vacuum.

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!

A Calorie unit used in food is equal to the amount of energy necessary to raise the temperature of 1 kilogram of water ________
Kitty [74]

A Calorie unit used in food is equal to the amount of energy necessary to raise the temperature of 1 kilogram of water by <u>1</u> degrees Celsius.

<h3>What is One Calorie ?</h3>

The amount of heat energy required to raise the temperature by 1 gram of water through 1°C is known as One Calorie.

1 Calorie = 4.18 J

Thus from the above conclusion we can say that A Calorie unit used in food is equal to the amount of energy necessary to raise the temperature of 1 kilogram of water by <u>1</u> degrees Celsius.

0.200 grams of HCl is dissolved in 0.801 grams water. The density of the solution formed is 1.10 g/mL. What is the molarity of t
alina1380 [7]

Answer:

M=6.03M

Explanation:

Hello,

In this case, since the molarity is computed by:

M=\frac{n_{solute}}{V_{solution}}

Whereas the solute is the hydrochloric acid, we compute the corresponding moles with its molar mass (36.45 g/mol):

n_{solute}=0.200gHCl*\frac{1molHCl}{36.45gHCl} =0.00549molHCl

Next, since the solution contains both HCl and water, we compute the volume in liters by using its density:

V_{solution}=(0.200+0.801)g*\frac{1mL}{1.10g} *\frac{1L}{1000mL} =9.1x10^{-4}L

Therefore, the molarity turns out:

M=\frac{0.00549mol}{9.1x10^{-4}L}\\ \\M=6.03M

Regards.
