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>

The answer is- Part washers use cleaning solutions that eventually become spent and must be disposed of properly.
Cleaning solutions: Cleaning solution is a liquid solvent or solution used to clean the working surfaces and the parts of a machine.
What type of cleaning solution is Part washers?
- Parts washers are mechanical devices that are designed to be cleaned to remove debris, dirt, oil, paint, and other substances that could potentially contaminate parts to prepare them for assembly, packaging, or even painting.
- They are basically used to clean parts to make them ready for functional use.
- Cleaning solutions for washing used parts are considered a special waste because they can be hazardous waste and are waste from an industrial process.
- Used solvents are almost always hazardous waste. Both solvent and aqueous parts washers produce a sludge that is usually hazardous because it contains toxic metals and solvents from the parts being cleaned.
- Absorbents used to wipe parts after washing are also dangerous if they contain toxic metals in concentrations exceeding regulatory limits or listed hazardous solvents, and used oil may also contain hazardous waste.
- Thus, these cleaning solutions must be disposed of properly.

Answer:
The reaction shifts to the left.
Explanation:
Equilibrium constant (K) = 46.3
Reaction Quotient (Q) = 525
The relationship between Q and K with their implications are given as;
K = Q (No net reaction)
K > Q (Reaction shifts to the right)
K < Q (Reaction shifts to the left)
Since in this question, Q (525) > K (46.3)
The reaction shifts to the left.
Answer:
