Answer:

C) Temperature and Kinetic Energy.

Explanation:

Hello there!

In this case, according to the generic heating curve on the attached file, it possible to see that on the point C, whereas the line is diagonal, the temperature increases, but also the kinetic energy increases because the molecules gain energy due to the increase of the temperature. It is important to say that on flat lines, like those on B and D, the phase change takes place and just the potential energy change.

In such a way, we infer that the answer is C) Temperature and Kinetic Energy.

Best regards!

chegg write a net ionic equation describing the oxidation of no2 2 to no3 2 by o2 in a basic solution.

Marina86 [1]

When the same species undergoes both oxidation and reduction in a single redox reaction, this is referred to as a disproportionation. Therefore, divide it into two equal reactions.

NO2→NO^−3

NO2→NO

and do the usual changes

First, balance the two half reactions:

3. NO2 +H2O →NO^−3 + 2 H^+ + e−

4. NO2 +2 H^+ + 2e− → NO + H2O

Now multiply one or both half-reactions to ensure that each has the same number of electrons. Here, Eqn (3) x 2 results in each half-reaction having two electrons:

5. 2 NO2 + 2 H2O → 2 NO^−3 + 4H^+ + 2e−

Now add Eqn 4 and 5 (the electrons now cancel each other):

3NO2 + 2H^+ + 2H2O → NO + 2 NO−3 + H2O + 4H+

and cancel terms that’s common to both sides:

3NO2 + H2O → NO + 2NO^−3 + 2H+

This is the net ionic equation describing the oxidation of NO2 to NO3 in basic solution.

I REALLY NEED HELP!! Is rubbing alcohol polar, non polar or ionic? Does it mix with water? Does it mix with vinegar?

Taya2010 [7]

Answer:

You can mix both with rubbing alcohol, and rubbing alcohol is ionic.

Explanation:

To mix them together:

Combine 1 cup rubbing alcohol, 1 cup water, and 1 tablespoon of white vinegar into a spray bottle. The solution can kill germs and clean counters, according to Reader's Digest.

Rubbing alcohol is both polar and iconic.

Hope that this helps you and have a great day :)
