Answer:
5
Step-by-step explanation:
dont really understand why you answered your own question?
The amount of heat released when 12.0g of helium gas condense at 2.17 K is; -250 J
The latent heat of vapourization of a substance is the amount of heat required to effect a change of state of the substance from liquid to gaseous state.
However, since we are required to determine heat released when the helium gas condenses.
The heat of condensation per gram is; -21 J/g.
Therefore, for 12grams, the heat of condensation released is; 12 × -21 = -252 J.
Approximately, -250J.

Answer:
70°
Step-by-step explanation:
The tangent- chord angle is one half the measure of the intercepted arc.
intercepted arc = 360° - 220° = 140°, thus
inscribed angle = 0.5 × 140° = 70°
Vertical angles i believe is the right answer to this problem
For this, all you'll wanna do is add the answer to this problem to your original number...
16× .75 = 12
now add...
16 + 12 = 28$ per pound...
to make a 75% profit on the markets investment....I think I'll have a salad instead at that price...
