Question
Consider the explanation in the Introduction regarding the determination of qrxn, and answer the following questions about the reactions that you will be performing in this experiment.
Part A: How are qsoln and qrxn related to one another?
A.)They are equal
B.)They are unrelated
C.)-qsoln = qrxn
Part B) Consider the explanation in the Introduction regarding the determination of qrxn, and answer the following questions about the reactions that you will be performing in this experiment.
Based on your answers to the previous questions,
Will qrxn be a positive or negative quantity?
A.) Positive
B.) Negative
C.) Zero
Part C). A student observed that, when 0.243 g of magnesium was added to 100.0 g of hydrochloric acid, the temperature of the solution increased 11.2 °C.
Without doing any calculations, what observations can you make to determine if this reaction was endothermic or exothermic? Select the best pairing of reasonable observation and conclusion.
Group of answer choices
A.) The temperature of the solution decreased; therefore the reaction was endothermic
B.)The temperature of the solution decreased; therefore the reaction was exothermic
C.)The temperature of the solution increased; therefore the reaction was endothermic
D.)The temperature of the solution increased; therefore the reaction was exothermic
