50.0 mL of 0.200 M solution of aluminum nitrate was mixed with 200 mL of 0.180 M solution of sodium carbonate.
Balance the equation, give the states of the products, and determine the Limiting Reactant.
Calculate the actual flow rate of air (70% excess) including O2 and N2 flow rates - Propaen is completely burned and its conversion is 95 %. Determine the complement molar flow rates of the flue gases.
Electrolysis can be used to determine actomic masses. A current of .600 amperes deposits 2.42 grams of a certain metal from its salt solution in 1.00 hour. A second experiment shows that the dissolved salt of the metal is in a +1 oxidation state.
