What is coefficientof Ixgen in the balanced reason: _ _ C2H4 + _ _ O2 --> _ _ CO2 + _ _ H2O

The coefficient for Oxygen in the balanced reaction : 3

Further explanation

Given

Reaction

C₂H₄ + _ _ O₂ ⇒ _ _ CO₂ + _ _ H₂O

Required

Oxygen coefficient

Solution

1. Give a coefficient

C₂H₄ + aO₂ ⇒ bCO₂ + cH₂O

C, left=2, right=b⇒b=2

H, left=4, right=2c⇒2c=4⇒c=2

O, left=2a, right=2b+c⇒2a=2b+c⇒2a=2.2+2⇒2a=6⇒a=3

The equation becomes :

C₂H₄ + 3O₂ ⇒ 2CO₂ + 2H₂O

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

Ithink its solid. hope this
