Answer:
1.2 × 10² J
Explanation:
Given data
- Initial temperature: 295 K
The amount of heat (Q) that a substance absorbs depends on its specific heat capacity (c), which is the amount of heat energy required to raise the temperature of a substance per unit of mass. It can be calculated through the following expression. <em>(cFe = 0.444 J/g.K)</em>
Can u give us a clear question please
Answer:
b. The solvent being used in the experiment.
Explanation:
The spectrophotometer indicates the absorption of the light for the substance. So, during the experiment, is necessary to put the solvent first, so the equipment will discount the absorption of it, and then, with the samples, will indicate the absorption of the solute.
