Answer:
Explanation:
Hello!
In this case, since this calorimetry problems can by analyzed by figuring out that the heat lost due to the combustion of C6H12O6 is gained by the water and the calorimeter which undergo the mentioned temperature rise, we can write:
Thus, by plugging in the given data, we obtain:
Next, we compute the moles of C6H12O6 by using its molar mass (180.18 g/mol) as shown below:
Thus, the value for q of the reaction turns out:
Best regards!
A. is the answer, because the more an experiment is repeated, it will become apparent if it yields the same results thus confirming or debunking the hypothesis.
Answer:
1125.75 cm³
Explanation:
We are given;
Initial volume; V1 = 673 cm³
Initial temperature; T1 = 275 K
Final temperature; T2 = 460 K
From Charles law, we can find the new volume from;
V1/T1 = V2/T2
V2 = (V1 × T2)/T1
V2 = (673 × 460)/275
V2 = 1125.75 cm³
