An automobile gasoline tank holds 46 kg of gasoline. When the gasoline burns, 161 kg of oxygen is consumed and carbon dioxide and water are produced. What is the total combined mass of carbon dioxide and water that is produced?

The mass of products is 207kg

Explanation:

To solve this question we can do mass balance assuming the engine that contains the gasoline produce only carbon dioxide and water, that is:

Mass of reactants = Mass of products

Where mass of reactants is mass of gasoline  + Mass oxygen = 207kg

That means the combined mass of products is 207kg

the answer is b & c i believe : )

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 :
