. Consider the following reaction : 4NH3+502 → 4NO + 6H20,suppose we start the reaction with 100 molecule of NH3 and 100 molecule of
O2, what will be the total number of molecule (reactant and product)
after this reaction goes to completion?

Why do cells appear different in distilled water than they do in 10% salt water?

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.

3) in peaches, [oh]=3.16x10-11 m a) find [h+ ] b) what is the ph? c) is the solution acidic, basic, or neutral?
