2c8h18(g 25o2(g→16co2(g 18h2o(g how many moles of water are produced in this reaction

The amount of water produced is 18 moles.

Explanation:

The given chemical reaction follows:

By Stoichiometry of the reaction:

2 moles of octane gas reacts with 25 moles of oxygen gas to produce 16 moles of carbon dioxide gas and 18 moles of water molecule.

Number of water molecules produced = 18 moles

Hence, the amount of water produced is 18 moles.

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 :
