Answer:
17.92 litres.
Explanation:
1 mole of a gas occupies 22.4 litres at STP.
So 0.8 moles occupies 0.8 * 22.4
= 17.92 litres.
The reaction is
2H₂(g) + O₂(g) ---> 2H₂O
Thus as per balanced equation two moles of hydrogen will react with one moles of oxygen.
There is a directly relation between moles and volume. [One mole of each gas occupies 22.4 L of volume at STP]
Thus we can say that two unit volume of hydrogen will react with one unit volume of oxygen
Now as we have started with equal units of volume of both oxygen and hydrogen, half of oxygen will be consumed against complete volume of hydrogen
so the gas which will remain in excess is oxygen
2/1.01=1.980=2
32.7/32.07=1.020=1
65.3/16.00=3.969=4
H2SO4. oxygen is 1
Cool liquid from 314 K to 273 K, freeze liquid at 273 K, and cool solid to 263 K.
a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
