Consider this reaction 2mg(s)+o2(g) > 2mgo(s) what volume (in milliners) of gas is required to react with 4.03 g mg at stp ? a)1860 ml b)2880 ml c)3710 ml d)45,100 ml

The volume of a gas that is required  yo react with 4.03 g mg  at STP  is 1856 ml

calculation/

     moles=mass/molar mass

moles of Mg is therefore=4.03 g/  24.3 g/mol=0.1658  moles

  the moles 02=0.1679 x1/20.0829 moles

                            0.0895 moles=? L

into Ml = 1.8570 x1000=1856  ml  approximately to 1860

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

they are all solids.
