Nitrogen and hydrogen react to form ammonia. consider the mixture of n2 (blue spheres) and h2 (gray spheres) in the illustration. all but one statement regarding the reaction is truea)nitrogen is in excess. b)hydrogen is in excess. c)this is a synthesis reaction. d)hydrogen is the limiting reactant.

Option (C) is the correct answer.

Explanation:

A reaction in which two or more reactants combine to result in the formation of a single product is known as a synthesis reaction.

For example, is a synthesis reaction.

Whereas the number of moles of either nitrogen or oxygen is not given. Therefore, we cannot tell which reactant is in excess or not.

Thus, we can conclude that the statement, this is a synthesis reaction is the true statement.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
