The coefficient for Oxygen in the balanced reaction : 3
<h3>Further explanation</h3>
Given
Reaction
C₂H₄ + _ _ O₂ ⇒ _ _ CO₂ + _ _ H₂O
Required
Oxygen coefficient
Solution
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
Answer:
Nitrogen and oxygen are the most common elements in the atmosphere. They make up almost 99% of the atmosphere by mass. Argon makes up most of the rest of the atmosphere.
Orbitals are space around the nucleus where electrons orbit. Several orbitals can exist in a given energy level/shell. Carbon is the sixth element of the periodic table with 6 electrons. Carbon atoms have the ability to bond to themselves and to other atoms with sp, sp² and sp³, hybrid orbitals. Several orbitals in carbon are spherical conformation and this accounts to about 40% of the orbitals.
