Answer:
Pully
Explanation:
I would think that a pully would be most effective for lifting it Up and into the apartment (at least if you have a suitable spot to put the pully)
Answer:
D. A burning candle. (chemical energy into energy of heat and light, i.e. thermal and wave)
Explanation:
comment and tell me if it right.
The volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.
Explanation:
The kinetic theory of gases is mostly based on Boyle's law. From the Boyle's law, the pressure experienced by any gas molecules is inversely proportional to volume of the gas molecules. Also this inverse relation is obeyed if and only if the number of moles and temperature of the gas molecules remained constant.
So,
So if there is a change in pressure then there will be inverse change in volume. That means if there is decrease in the pressure of gas molecules then there will be increase in the volume and vice versa.
So the Boyle's law is combined as 
As here the initial pressure or
is 1 atm or 101.3 kPa and the initial volume is 478 mL. Similarly, the final pressure is 93.3 kPa and the final volume will be


So, the volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.
You have to put your attention to the unit of concentration. It is expressed in terms of molarity, which is represented in M. It is the number of moles solute per liter solution. So, you simply have to multiply the molarity with the volume in liters.
Volume = 275 mL * 1 L/1000 mL = 0.275 L
<em>Moles Ba(OH)₂ = (0.200 M)(0.275 L) = 0.055 mol</em>
