Question 1 4 pts If, during the reaction, your measured temperature increases, should your final calculated value for the experimental AHxn be positive or negative, and why? Choose the ONE best answer. o It should be negative because heat was absorbed since the temperature increased. It should be positive because if the water got hotter then the reaction got colder which is endothermic o It should be positive because heat was absorbed since the temperature increased. o It should be negative because the reaction released heat to the water which got hotter. O It should be positive because the reaction released heat to the water which got hotter.
Question 2 4 pts For the reactions involving aqueous solutions, how will the masses of each solution be determined? The moles will be calculated using the measured volume and the solution molarity, then molar mass will be used to find the grams. o if you know the volume in milliliters, then you automatically know the mass in grams because they are the same. Use PV RT to get moles then molar mass to get grams. o It will be measured on the analytical balance, It will be calculated from the measured volume and the density of the solution, assumed to be the same as the density of water
Question 3 12 pts Choose the unit that will be used in this experiment for each of the following quantities. It is possible that some answer choices may be used more than once, and others may not be used at all.
