Question

question 5
this diagram represents the synthesis of nitrogen monoxide. what is the balanced equation
of this chemical reaction?
o n₂ + o₂ → no
o n₂ + o₂ → 2no
o n₂ + 2o₂ → no₂
o 2n₂ + 2o₂ → 2no

Explanation:

Step1: Count atoms on reactant side

• For \(N_2\): 2 nitrogen atoms.
• For \(O_2\): 2 oxygen atoms.

Step2: Check each option for atom balance

• Option \(N_2 + O_2

ightarrow NO\):

• Reactant: 2 N, 2 O.
• Product: 1 N, 1 O. Not balanced.
• Option \(N_2 + O_2

ightarrow 2NO\):

• Reactant: 2 N, 2 O.
• Product: \(2\times(1\ N + 1\ O)=2\ N, 2\ O\). Balanced.
• Option \(N_2 + 2O_2

ightarrow NO_2\):

• Reactant: 2 N, \(2\times2 = 4\ O\).
• Product: 1 N, 2 O. Not balanced.
• Option \(2N_2 + 2O_2

ightarrow 2NO\):

• Reactant: \(2\times2 = 4\ N, 2\times2 = 4\ O\).
• Product: \(2\times(1\ N + 1\ O)=2\ N, 2\ O\). Not balanced.

Answer:

\(N_2 + O_2
ightarrow 2NO\)
