Answer:
The uncertainty due to the equipment on chemistry equipment is equal to +-1/2 of the smallest unit marked in your equipment; in this case you have a pipette and its sameelst mark is 0.1 mL, so the uncertainty will be 0.05 mL. If you divide 0.05 mL / 3.2 mL and multiply it by 100 you get 1.56% of uncertainty if you measure 3.2 mL, so it will be proper to report the measurement and also the uncertainty.
Hence 2.107 x 10^23 atoms are present in 41.7 g of tin(Sn).
Mass of 2.37 x 10^22 atoms of Xe is 5.12031 g.
Hope this helps, have a great day/night ahead!

<span>The benefit of the space shuttle is that A. it's reusable. This means that after this shuttle has been used for one mission, it can be use for numerous other missions again, until it gets broken and cannot run anymore. B is incorrect because it cannot land - it is only there to observe. C is incorrect because more than one person can fit. D is incorrect because it doesn't orbit the Earth permanently - it returns at one point.</span>
Answer:
Lewis acids and bases are most closely associated with ELECTRON TRANSFER. A Lewis acid is defined as as a chemical specie that can accept an electron pair from a Lewis base to form a Lewis adduct while a Lewis base is defined as a specie which can donate an electron pair to a Lewis acid or an acceptor compound. Thus, Lewis base and acid has to do with electrons transfer.
