At STP (standard temperature and pressure) 1 mole of a gas takes up 22.4L
so 2.33/22.4=0.104 mol H2S
The only metalloid located in the sixth period of the periodic table is Astatine. Others are located in previous periods.
Number of moles of NO2 = 11.5/(14+16x2) =0.250mol
Mole ratio: 4NO2 to 1O2
Number of moles of O2=0.250/4 =0.0625mol
Mass of O2 produced= 0.0625x32 =2g
Answer: B
Answer:
During the process of electrolysis, ions that are formed will get discharged to reform neutral atoms at the state of electrons, whereas the preferential meaning which in case one or more kind of cations and anions in the electrolyte, the one with the higher concentration or at a lower position activity will get discharged first.
