Aluminium Carbonate on Dissociation produces Aluminium Ions and carbonate Ions as follow,
Al₂(CO₃)₃ → 2 Al⁺³ + 3 CO₃⁻²
Result:
On dissociation Al₂(CO₃)₃ produces FIVE Ions in total. The Ions produced and there number are as follow;
Al⁺² = 2
CO₃⁻² = 3
28 gram of c2h4 must burn as it is equavilant to 1 mole of c2h4
The correct answer is 0.9803 atm
Given, pressure of nitrogen = 745 mmHg
Conversion factor: 760 mmHg = 1 atm
Converting 745 mmHg to 1 atm
745 mmHg x ( 1 atm / 760 mmHg) = 0.9803 atm
So is the pressure of nitrogen is 0.9803 atm
The CH4 molecule has the lowest molecular weight, so it has the lowest boiling point.
Hope I helped :)
