How much Cu 60 half life 24 min would remain from a 4 mg sample after 48 min?
1mg. If the half life is 24 minutes then in 48 minutes the sample would decay twice. After one half life the mass would halve (to 2mg) and after the second it would have again (to 1mg).

How much would still remain in 30 minutes if you had a 5 - grm sample of lawrencium?
The half life is different for each isotope of Lr; name the isotope.

How would you distinguish a sample of peat from a sample of mudstone that contains fossil plant fragments?
Peat would remain largely unconsolidated. Mudstone is a rock.
Will lawrencium combine with other elements?
We would expect Lawrencium to react with other elements similar to the way scandium or yttrium do, these being in the same column of the periodic table. However, lawrencium is highly radioactive, and most of the isotopes have half-lives in the seconds; the longest lived isotope has a half-life of 40 minutes, so that doesn't give chemists much time to work with it.
