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

Given that the gas inside the balloon is an ideal gas, then the ideal gas equation can be used to describe the system. I think the correct answer from the choices listed above is option B. If the balloon is heatedto a temperature of 15.5T while it is placed under a high pressure of 15.5P, then the volume of the balloon stays the same since the change in temperature corresponds to same degree of change with pressure.
Answer: There are 3 unpaired electrons on aluminium in aluminium oxide.
Explanation:
Chemical formula of aluminium oxide is 
.
The atomic number of aluminium is 13 and its electronic configuration is 
. In order to complete its octet, aluminium will lose or donate 3 electrons to the oxygen atom as it has 3 electrons in excess.
Thus, there are three unpaired electrons on one aluminium atom.
Since, there are two aluminium atoms in , so, there will be in total 6 unpaired electrons on two aluminium atoms. Whereas each oxygen atom has deficiency of 2 electrons so, each aluminium atom will donate its excess of electrons to each oxygen atom.
