Answer:
2.58g
Explanation:
First calculate the moles of butane used in the reaction
moles = mass÷molar mass
= 0.85÷58
= 0.0147
According to the stoichiometric ratio:
C4H10 : CO2 = 2:8
moles of CO2 =(8÷2)×0.0147
=0.0586 moles
mass of CO2 = 0.0586×44
= 2.58g
False. A mixture represents elements or molecules which are not chemically combined.
Your task is to measure the amount of energy evolved during the combustion of some hydrocarbon, then the ideal technique for this experiment would be : Bomb calorimetry
<h3>What is bomb calorimetry?</h3>
Hydrocarbons are combustibles means that they can react in a combustion reaction to produce energy. To measure this energy, it's a necessary equipment so that the reaction can be placed in a controlled way.
The bomb calorimeter is the equipment, which is an adiabatic vessel, with water and heat is calculated based on the increase in the temperature of the water.
Coffee-cup calorimetry is used to measure the heat of a dissolution reaction and bomb manometry is used to measure the pressure.
