2. The addition of dimethylglyoxime, H₂C4H6O₂N2, to a solution containing nickel(II) ion gives rise to the precipitate, Ni(HC4H6O₂N2)2: N₁²+ + H₂C4H6O₂N₂ → 2H+ + Ni(HC₂H5O₂N2)2 (s) Nickel dimethylglyoxime is a bulky precipitate that is inconvenient to manipulate in amounts greater than 175 mg. The amount of nickel in a type of permanent-magnet alloy ranges between 24% and 35%. Calculate the amount of sample that should not be exceeded when analyzing these alloys for nickel.

6. Some sulfuric acid is spilledon a lab bench. You can neutralizethe acid by sprinkling sodiumbicarbonate on it and then moppingup the resultant solution. The sodiumbicarbonate reacts with sulfuric acidas follows:2 NaHCO3(s) + H2SO4(aq)Na2SO4(aq) + 2H2O(l) + 2CO2(g)Sodium bicarbonate is added until thefizzing due to the formation of CO2(g)stops. If 27 mL of 6.0 M H2SO4 wasspilled, what is the minimum mass ofNaHCO3 that must be added to thespill to neutralize the acid?
