Answer:
The final temperature will be close to 20°C
Explanation:
First of all, the resulting temperature of the mix can't be higher than the hot substance's (80°C) or lower than the cold one's (20°C). So options d) and e) are imposible.
Now, due to the high heat capacity of water (4,1813 J/mol*K) it can absorb a huge amount of heat without having a great increment in its temperature. On the other hand, copper have a small heat capacity (0,385 J/mol*K)in comparison.
In conclusion, the copper will release its heat decreasing importantly its temperature and the water will absorb that heat resulting in a small increment of temperature. So the final temperature will be close to 20°C
<u>This analysis can be done because we have equal masses of both substances. </u>
Adding oxygen will cause the equation of
CO-Hemogoblin + O2= Hemogoblin = Oxyhemogoblin
to the right. This is because the increase in pressure leads to more on the left side, and as such a balance needs to be maintained so the equation shifts to the right.
The answer to that is mass and chemical
Answer: b.) they tend to lose electrons to gain stability
