A feed stream consisting of 1.900% argon (by mole) and stoichiometric proportion of the reactants is fed into the system at the rate of 100 mol/min. The components enter a reactor, and then all ammonia is separated from the other components and leaves the process. The other components are recycled back to the feed stream, with a portion being purged from the system. The mole percentage of argon in the purge stream is 4.700%, and the conversion per pass in the reactor is 11.00%. What is the production rate of ammonia

- 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

c (diamond),

sio2 (quartz)
