Is copper penny react<br> reaction with Nitric<br> acid a<br> Chemical or physical<br> Change?
riadik2000 [5.3K]

Answer:

The reaction that occurs is a redox reaction. The Copper metal (Cu 0)on the copper pennies is oxidized in concentrated nitric acid to produce Cu2+ ions. Copper is easily oxidized to Cu2+, which is blue in aqueous solutions (water) so you should see the solution turn blue as the copper penny reacts.

Have a nice day ;)(^-^)

alexdok [17]

Answer:

London dispersion forces

Explanation:

The London dispersion force is the weakest kind of intermolecular force. The London dispersion force is a temporary attractive force that occurs when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.

These London dispersion forces are mostly seen in the halogens (e.g., Cl2 and I2), the noble gases (e.g., Xe and Ar), and in many non-polar molecules, such as carbon dioxide and propane. London dispersion forces are part of the van der Waals forces, and are very weak intermolecular attractions.

Imagine two solutions with the same concentration and the same boiling point, but one has ethanol as the solvent and the other h
Anna71 [15]

Imagine two solutions with the same concentration and the same boiling point.?

Imagine two solutions with the same concentration and the same boiling point, but one has ethanol as the solvent and the other has carbon tetrachloride as the solvent. Determine that concentration and boiling point.

ethanol: 78.4 °C Kb=1.22 c/m

carbon tetrachloride: 76.8 °C Kb=5.03 c/m

Answer:

The molal concentrations are 0.42 m.

Explanation:

This question seeks to explain the boiling point elevation as a colligative property of a mixture.

Colligative property of a mixture/solution is one that describes any property of that that depends only on the number of molecules present.

∆T=Kb.m

∆T - Change in boiling point

Kb- boiling point constant

m - molality

The change in boiling points are 1.6 degrees apart; i.e.,∆T= 78.4-76.8 = 1.6 so the CCl4 must increase 1.6 more than the ethanol.

Remember that

If you want the boiling point to be the same, that means you want

T (ethanol) = T (CCl4)

T (CCl4) =5.03*m

∆T = [1.22*m + 1.6]

[1.22*m + 1.6] = 5.03*m

If concentration is the same;

and solve for m

m = 0.42.

We can check that out from

∆T = Kb*m

∆T(ethanol)= 1.22*0.42 = 0.51

so boiling point. = 78.4 + 0.51 = 78.9

∆T(CCl4) = 5.03*0.42 = 2.1

so boiling point. = 76.8 + 2.1 = 78.9

and the boiling point are the same.

The molal concentrations are 0.42 m.
