I’m studying for my Chemistry class and don’t understand how to answer this. Can you help me study?

Hello, the following are two worksheets that need to be done, in order to get to answer them you will need to use BeyondLabz which I will help you access if you don’t know how to.

#### For Beyond Labz Heat of Reaction: MgO (s) + HCl (aq)

In this simulation you will use coffee cup calorimetry to measure the heat transfer that occurs when magnesium oxide reacts with hydrochloric acid. You will use your results to calculate the enthalpy of the reaction (

$\Delta$

Hrxn) and compare it to a predicted value calculated using values for standard enthalpy of formation.

#### For Beyond Labz Hess’s Law

In this simulation you will use coffee cup calorimetry to measure the heat of reaction (

$\Delta$

Hrxn) for three reactions and show how they are related by Hess’s Law. You have to record data for three different reactions.

If you have any questions let me know!
