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

The coefficient for Oxygen in the balanced reaction : 3

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

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
