Naddika [18.5K]3 years ago
6 0

Answer:

volume = 13097674418.528dm³

Explanation:

n = (3.52)*10^32/(6.02)*10^23)

n = (584717607.97)

n = volume /molar volume

molar volume at stp = 22.4dm³

volume= 584717607.97 x 22.4

volume = 13097674418.528dm³

Given each pair, complete the sentences to determine which member of each has the stronger intermolecular dispersion forces.
evablogger [386]

Answer:

CH3CH2CH2Cl

CH3CH2CH2CH2CH2SH

Br2

Explanation:

Dispersion forces increases with increase in relative molecular mass. The specie having the greater relative molecular mass definitely has greater dispersion forces. A rough estimation of the relative molecular masses of the species stated in the answer will reveal this fact.

In the laboratory, a student dilutes 18. 9 ml of a 10. 0 m perchloric acid solution to a total volume of 250. 0 ml. what is the
Sever21 [200]

The concentration of diluted solution is 0.756M.

From the question given above, the following data were obtained:

Volume of stock solution (V1) = 18.9 mL

Molarity of stock solution (M1) = 10 M

Volume of diluted solution (V2) = 250 mL

Molarity of diluted solution (M2) =?

We can obtain the molarity of the diluted solution by using the dilution formula as shown follow:

M1V1 = M2V2

10 × 18.9 = M2 ×250

189 = M2 × 250

Divide both side by 100

M2 = 189 / 250

M2 = 0.756 M

Therefore, the molarity of the diluted solution is 0.756 M.

Thus the concluded that concentration of the dilute acid is 0.756 M.

A welding torch produces a flame by burning acetylene fuel in the presence of oxygen. the energy released from the acetylene fue
Sveta_85 [38]

A welding torch produces a flame by burning of acetylene fuel then energy released from the acetylene fuel is then used to melt a metal, so transformation of chemical energy into thermal energy takes place.

<h3>What is transfer of energy?</h3>

Energy neither can be produced nor destroyed but it only transfers from one form to other form.

In the question it is given that, burning of acetylene produces energy and this produced energy is a type of chemical energy and then this is used as a thermal energy for the melting of metal.

So conversion of kinetic energy to potential energy, thermal energy to electromagnetic energy and potential energy to chemical is wrong.

Hence transformation of chemical energy into thermal energy takes place.
