Argon and methane are absorbed from nitrogen into liquid ammonia at 2523 k and 175.0 atm. feed rate of gas is 100.0 kmol/h. feed gas contains 0.020 mol% ar and 0.130 mol% methane. outlet gas contains 0.0008 mol% methane. entering liqud ammonia is pure. operate with l/v-26.0. assume l and v flow rates are constam equilibrium data for methane is, partial pressure methane = 3600 atm and the partial pressure for argon = 7700 atm
a. find the outlet mole fraction of methane in the liquid
b. find the number of equilibrium stages required.
c. find the outlet mole fraction of argon in the gas.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
