We have a total feed of 100 kg/h to a countercurrent extraction column. the feed is 40 wt % acetic acid and 60 wt % water. we plan to extract the acetic acid with isopropyl ether. the entering isopropyl ether is pure and has a flow rate of 111.2 kg/h. we desire a raffinate that is 20 wt % acetic acid. a) find the acetic acid wt. fraction in the outlet extract stream b) determine the flow rates of the outlet raffinate and extract streams c) find the number of equilibrium contacts

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

How many liters of oxygen gas, at standard temperature and pressure, will react with 35.8 grams of iron metal? 4 fe (s) + 3 o₂ (g) → 2 fe₂o₃ (s)

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
