Answer:

a. The specific heat capacity of the gaseous ethanol is less than the specific heat capacity of liquid ethanol.

Explanation:

The heating curve is a curve that represents temperature (T) in the y-axis vs. added heat (Q) in the x-axis. The slope is T/Q = 1/C, where C is the heat capacity. Then, the higher the slope, the lower the heat capacity. For a constant mass, it can also represent the specific heat capacity (c).

Heats of vaporization and fusion cannot be calculated from these sections of the heating curve.

<em>Which statement below explains that?</em>

<em>a. The specific heat capacity of the gaseous ethanol is less than the specific heat capacity of liquid ethanol.</em> YES.

<em>b. The specific heat capacity of the gaseous ethanol is greater than the specific heat capacity of liquid ethanol.</em> NO.

<em>c. The heat of vaporization of ethanol is less than the heat of fusion of ethanol.</em> NO.

<em>d. The heat of vaporization of ethanol is greater than the heat of fusion of ethanol.</em> NO.

Complete these equations for the ionization of an Arrhenius acid or base in water. Include the states of the products.
Mazyrski [523]
1)
 HI(aq) → H⁺(aq) + I⁻(aq)
So this is an Arrhenius acid because it releases H⁺.

2)
LiOH(s) → Li⁺ + OH⁻
So this is an Arrhenius base because it releases OH⁻

when you started the activity, the can was open to the air outside tge can. how did the air pressure inside the can compare to t
aliya0001 [1]

The air pressure inside the can is lower compared to that of outside air pressure.

Explanation:

  • In general, the air pressure of an already opened can will be the same as the outside pressure.
  • Since the can is evacuated and remain as vacuum, so there will be no pressure difference in it.
  • If the can opens, air inside the can push the top and escapes to the outside.
  • This is due to high pressure experienced outside the can compare to that of lower pressure inside the can and this may even cause can to collapse itself.
