carbon chains can form branches and cross-links.
carbon compounds can be rings.
carbon monoxide is an organic compound.
each arrangement pf carbon atoms corresponds to a different compound.
carbon dioxide is an organic compound.

The statement which apply to carbon are:

Explanation:

Carbon chains can form branches and cross links which is termed as property of carbon an atom as catenation.

Organic compounds are those compounds in which hydrogen atoms are covalenlty bonded to carbon atoms. Also other atoms like oxygen and sulfur ,nitrogen are also bonded covalently to carbon atom may also be found.The other name for the organic compound is hydrocarbon.

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
