Answer:
0.035 m CH3CH2CH2OH
Explanation:
We know that freezing point is a coligative property hence it depends on the number of solute particles present.
Covalent substances do not break up into ions, hence they do not produce many particles in solution unlike ionic substances. Hence, ionic substances have a far higher freezing point than covalent molecules.
For this reason, 0.035 m CH3CH2CH2OH has the lowest freezing point.
Answer:
sure
Explanation:
The substance formed after heating the mixture of that of Rahul is caleed a compound. Whereas, Manav's mixture still remains in its current stae that is a heterogeneous mixture.
The compound formed is in black in color whereas the mixture is a mix of brownish-red and yellow.
The compound is a homogeneous mixture whereas the mixture is a heterogenous mixture because of its uneven distribution.
It’s d. 224 g that’s the answer
Answer:28.83g
Explanation: firstly write a balance equation for the reaction, which will be in this form C3H8 +4O2>>>>3CO2+ 4H2O. Then get the number of moles of propane and also for oxygen. Propane:0.227moles and oxygen: 0.901moles according to our eqution since the ratio is 1:4(1C3H8:4O2). Now convert the moles of O2 to mass, then it will be 28.83g
