The combustion of magnesium creates so much energy so quickly that it is hard to measure its enthalpy directly using a simple ca
lorimeter. However, you will break this reaction down into other intermediate reactions whose enthalpies you can – and will – measure. What broad question are you answering by doing this experiment?
Answer: Enthalpy of the reaction of combustion of magnesium
Explanation: The enthalpy of reaction of combustion of methane is usually determined by the usage of the Hess law .
Hess Law states that regardless of the multiple steps of the reaction, the total enthalpy change is equal to the sum of the enthalpies of all the steps involved.
Thus in order to find out the total change in enthalpy of magnesium oxide , we can break the reaction into several intermediate reactions whose entalpies can be easily determined.
So calculate the H for the other two reactions a room temperature and combine the reactions to calculate the H of the decomposition of calcium carbonate using the Hess's Law
From the question you will find that: one capsule of tamiflu is obtained from 2.6 g of star anise. 1 capsule = 2.6 g tamiflu ? capsules = 155 g tamiflu by cross multiplication = = 59 capsules
= 59 capsules
