KatRina [158]

Answer:

a. add a little distilled water to see which layer the water adds to

The problem tells us to keep in mind two major aspects of the test: It has to be <em>simple</em>, as well as <em>non-destructive</em>:

  • Adding distilled water can be made in under a minute, without requiring specialized laboratory equipment, unlike IR.
  • It is also non-destructive, because the contents on either layer won't change due to the added distilled water.

A 283.3-g sample of X2(g) has a volume of 30 L at 3.2 atm and 27 'C. What is element X?
professor190 [17]

we find the number of moles with the formula

pV=nRT

27C=300k

3.2*30=n*0.082*300

n=96/24.6=3.9 moles

we have the mass ant the number of moles so we can calculate the molar mass

283.3/3.9=72.64g/moles

that means X's mass is 72.64/2=36.3 so the element is Kr(Kriptonium)
