Explain why a cool flame is important in heating a solution to dryness

1 answer:

5 0

Hot flames have a tendency to make problem and as the there is evaporation of solution it infrequently gets overheated and the fluid progresses toward becoming super heated. That regularly makes "bumping" in which the problem area ejects and that is probably going to scatter any solid and on the off chance that you are doing quantitative work that implies the trial is demolished and if not at least it will be a mess, that is why cool flames are important to use instead of hot flames.

4P+ 5O2 -> P4O10

Ratling [72]

If 4 moles of P is used by 5 mole of O2
then....0.489 moles will be used by 5/4 × .489 = .611 moles of O2

so .611 moles

so if 4 moles of P is burnt , 1 mole of P4O10 is produced ....so for .489 moles...... .489/4=.122 moles !
so mass will be .122× 283.89 = 34.7 grams

so first ans is .611 moles and second is 34.7 grams !

if you have any problem regarding this , just comment !!!
