Q3. How many grams of sulfuric acid, H2SO4, can be obtained from 578 grams of iron ore if the ore is 86.0% by mass FeS? The reactions involved are given below. Reactions happen with the
yield of 92.0%, 84.0% and 95.5% respectively
4 FeS + 702 2 Fe2O3 + 4 SO2
2 SO2 + O2 +2 SO3
SO3 + H20 H2SO4

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.

Imagine that twenty i.u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?
