Write all properties of solution |
|
Answer» A solution is a HOMOGENEOUS mixture.(2) The particles of a solution are smaller than 1nm(10 −9 meter) in diameter. So, they can't be seen by NAKED eye.(3) Because of very small particle size, they do not scatter a beam of light passing through the solution. So the path of light is not visible in the solution.(4) The solute particles cannot be separated from the mixture by the PROCESS of filtration. The solute particles do not settle down when left undisturbed. That is, a solution is stable. |

What volume of ethane (NTP; 1 bar, 273 K) is formed from 38 g of sodium propionate by fusion with sode lime? |
|
Answer» 8.87LExplanation:Reaction of sodium carboxylate with sodalime is called sodalime decarboxylation reaction - Reaction is as follows:RCH₂COONa + NaOH → RCH₃ + Na₂CO₃ (in the presence of CAO which HELPS in keeping NaOH DRY)ACCORDING to given QUESTION,CH₃CH₂COONa + NaOH → CH₃CH₃ + Na₂CO₃1 mole of CH₃CH₂COONa = 1 mole of CH₃CH₃or, 38/96 mole of CH₃CH₂COONa = 38/96 mole of CH₃CH₃We know that at NTP, 1 mole gases occupy a volume of 22.4LSo, 38/96 mole of CH₃CH₃ will occupy a volume = 38 x 22.4/96 L = 8.87L |
