define the term limiting reagent point out the limiting reagent when 2

1.	define the term limiting reagent point out the limiting reagent when 20g of NaOH react with 98g of sulphuric acid
Answer» TION:H 2 SO 4 +2NaOH→Na 2 SO 4 +2H 2 OTHE molar masses of H 2 SO 4 and NaOH are 98 g/mol and 40 g/mol respectively.Number of MOLES is the ratio of mass to molar mass.Number of moles of H 2 SO 4 = 9849 =0.5 molesNumber of moles of NaOH = 4080.0 =2 moles0.5 moles of H 2 SO 4 will react with 2×0.5=1.0 mole of NaOH.2−1=1 mole of NaOH will remain unreacted. This corresponds to 1×40=40g.
