which of these is not a possible reason why the energy calculated from the experiment is always lower than the value given on the nutrition label? the snack did not fully react, leaving unmeasured energy. the energy goes into your stomach. some of the energy from the snack is lost to the air and can.
Answer
Brief Explanations:
To determine the incorrect reason, we analyze each option:
- "The snack did not fully react..." is a valid reason as incomplete reaction means some energy isn't measured, leading to a lower calculated value.
- "The energy goes into your stomach" is not a valid reason for experimental energy being lower. In experiments (like calorimetry), we measure energy released during combustion/reaction, and energy going to the stomach is not a factor in such experimental energy loss.
- "Some energy lost to air and can..." is valid as heat loss to surroundings (air, container) reduces the measured energy.
Answer:
The option "The energy goes into your stomach."
