Given a #3.00*g# mass of sodium metal, what mass of chlorine gas is equivalent? What mass of sodium chloride could be made given this quantity?
We assume a stoichiometric excess of chlorine gas......and we work out the mass of sodium chloride produced given 100% yield.
....and we must write a stoichiometric equation....
As written, this is a redox reaction, and sodium metal is oxidized by half an equiv of (binculear) chlorine gas....
And thus we should get
