(a)
Interpretation : A balanced chemical equation for the combustion of octane needs to be determined.
Concept Introduction : In a balanced
The enthalpy of reaction can be defined as the energy change during chemical reaction. The value is positive for an endothermic and negative for an exothermic reaction. If the energy is released in a reaction, the reaction is exothermic and if it is evolved, the reaction is endothermic.
(b)
Interpretation : The amount of energy produced in kJ from octane in one tank.
Concept Introduction : In the chemical reaction, reactant molecules react to form products. The mass of a substance is related to its number of moles and molar mass as follows:
Here, m is mass and M is molar mass.
Also, 1 mole of a substance contain
The enthalpy of reaction can be defined as the energy change during chemical reaction.
(c)
Interpretation : The number of molecules of octane present in 1 tank of fuel needs to be calculated.
Concept Introduction : In the chemical reaction, reactant molecules react to form products. The mass of a substance is related to its number of moles and molar mass as follows:
Here, m is mass and M is molar mass.
Also, 1 mole of a substance contain
The enthalpy of reaction can be defined as the energy change during chemical reaction.
(d)
Interpretation : The mass of carbon dioxide produced from the combustion of fuel if the car covers 24500 miles in a year.
Concept Introduction : From the number of moles, mass can be calculated as follows:
Here, n is number of moles and M is molar mass.
From the distance travelled, the volume of fuel consumed can be calculated from its mileage.

Today it is used in fireworks, model rocket engines, and replica black powder weapons. Black powder consists of potassium nitrate (potassium nitrate, KN03), charcoal and sulfur. A variety of chemical reactions take place when this mixture is exploded. One of these is shown below. 2KNO, +S+ 30 → K, S+N, ↑+3C0, 1 Knowing that carbon makes up 15% of the black powder, calculate the total volume of gases (under normal conditions) released when 0.1 kg of black powder explodes.
