Sulfuric acid is formed when sulfur dioxide reacts with oxygen and water. Write a balanced chemical equation for the reaction. (Use the lowest possible coefficients. Include states of matter under the SATP conditions in your answer.)

How many mol H2SO4 is produced from 11.5 moles of SO2?

How many O2 is needed?

Balanced chemical equation for the reaction is:

2S (g) + (g)+ 2O (l) ⇒

Moles of formed is 5.75 moles.

Moles of oxygen used is 5.75 moles in the reaction.

Explanation:

Data given:

moles of S = 11.5 moles

moles of = ?

Moles of needed =?

balanced equation with states of matter =?

Balanced chemical reaction under STP condition is given as:

2S(g) + (g) + 2O (l) ⇒

From the balanced reaction 2 moles of sulphur dioxide reacted to form 1 mole of sulphuric acid:

so, from 11.5 moles of S, x moles of is formed

2x = 11.5

x = 5.75 moles of sulphuric acid formed.

From the balanced reaction 1 mole of oxygen reacted to form 1  mole of sulphuric acid.

when 11.5 moles of Sulphur dioxide reacted then oxygen in the reaction is 5.75 moles.

idk what is it? is this a question that you know the answer or u dont
