How many moles of o2 are needed to react completely with 35.0 mil c2h2?

We know that this is a combustion question since it contains a hydrocarbon being burned with oxygen. Therefore the products are water and carbon dioxide.

C₂H₂+O₂⇒H₂O+CO₂

Balancing this,

2C₂H₂+5O₂⇒2H₂O+4CO₂

We know that 2 moles of C₂H₂ will react with 5 moles of O₂. From the balanced equation.

We can set up our ratios:2:5=35:x

2x=175

x=87.5

Therefore it would require 87.5 moles of O₂

Im not sure if this is correct, im just trying to help. :/

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
