Warm is less heaver then cold air so warm air rise and cold air sinks
The answer is false. The particles in a suspension are not dissolved into the solvent rather they are suspended or dispersed into the solvent, Suspension is a heterogeneous mixture where solute-like particles settle out of a solvent-like phase. Examples are mercury in shake in oil, oil shake in water, and chalk in water.
C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O
The balanced equation for the formation of ammonia is as follows
N₂ + 3H₂ --> 2NH₃
stoichiometry of H₂ to NH₃ is 3:2
Avagadros law states that at volume of gas is proportional to number of moles of gas at contant pressure and temperature
therefore molar ratio is equivalent to volume ratio
hence, volume ratio of H₂ to NH₃ is 3:2
if 2 L of NH₃ requires 3 L of H₂
then 3.0 L of NH₃ requires - 3/2 x 3.0 L = 4.5 L of H₂
volume of H₂ required is
