For the haber process, n2+3h2 yields 2nh3, what volume of nitrogen is consumed at stp if you collect 44.8 l of ammonia in excess hydrogen (n=14 amu, h=1 amu)
a. 14.9 l
b. 29.9 l
c. 44.8l
d. 22.4 l

d. 22.4 L

Explanation:

According to Avogadro's law , 1 mole of every gas occupies 22.4 L of volume at STP.

moles of ammonia=

Given: Hydrogen is the excess reagent and nitrogen is the limiting reagent as it limits the formation of product.

From the given balanced equation:

2 moles of ammonia is produced by 1 mole of nitrogen.

Thus 2 moles of ammonia is produced by 22.4 L of nitrogen at STP as 1 mole of nitrogen occupies 22.4 L at STP.

- 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
