Answer:

1.

Solid: A, B, and C.

Liquid: D and E.

Gas: F.

2.

Into liquid on warm day (37 °C): D and C.

Into a liquid only when heated slightly: C and E.

From liquid to solid readily when placed into a freezer (0 °C): D.

Explanation:

Hello!

In this case, since the melting point is the temperature at which a substance change from solid to liquid and the boiling point from liquid to gas, we understand that substance at a temperature below the melting point is solid, whereas above are liquid; moreover, below the boiling point they are liquid and above gaseous.

In such a way, we have:

1.

Solid: A, B, and C.

Liquid: D and E.

Gas: F.

2.

Into liquid on warm day (37 °C): D and C.

Into a liquid only when heated slightly: C and E.

From liquid to solid readily when placed into a freezer (0 °C): D.

Best regards!

Do polar molecules conduct energy as well as ionic molecules?
castortr0y [4]

Answer:

Polar molecules typically do not conduct electricity as well as ionic molecules. This is because charges in polar molecules due to unequal sharing of electrons are not as strong as the charges on ions

A 25. 00 ml sample of acetic acid containing phenolphthalein indicator is titrated with 0. 1067 m naoh. The solution changes col
sasho [114]

The concentration of acetic acid:

The concentration of the acetic acid before titration is 0.128 M

What is titration?

Titration is a quantitative analytical procedure that works by allowing a known analyte to gradually react with a titrant until an endpoint is reached.

Titration for weak acid and strong base:

Moles of acetic acid =  moles of NaOH

Given:

Concentration of NaOH = 0.1067 M

Volume of NaOH = 30.07 ml = 0.03007 L

Calculation:

So, by using the formula, Concentration = Moles/Volume

Moles of NaOH = concentration x volume = 0.1067 x 0.03007 = 0.0032

Therefore, the moles of acetic acid  = 0.0032 mole

Now, using the formula again for determining the concentration of acetic acid, we get,

Concentration = Moles/Volume

Concentration of acetic acid =  0.0032/0.025 = 0.128M
