How many grams of oxygen gas are needed to react completely with 38.442 grams of sulfur dioxide gas? so2(g) + o2(g) --> so3(g) (needs to be balanced)

19.221 grams of oxygen gas are needed to react completely with 38.442 grams of sulfur dioxide gas.

Explanation:

Given :

After balancing,

According to reaction ,2 moles of reacts with one mole of then 1.2013 moles of will react with :

Mass of required =

19.221 grams of oxygen gas are needed to react completely with 38.442 grams of sulfur dioxide gas.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
