Answer: The quantity of heat required is 358.644 J.
Explanation:
Given: Specific heat capacity =
Mass = 1.50 g
Formula used to calculate heat energy is as follows.
where,
q = heat energy
m = mass
C = specific heat capacity
= initial temperature
= final temperature
Substitute the values into above formula as follows.
Thus, we can conclude that quantity of heat required is 358.644 J.

Why is there no reaction between silver and copper (II) nitrate?</h3>
For the reaction to occur, it is necessary that the metal which replaces the metal from the compound LIES above that metal in the ELECTROCHEMICAL SERIES(ECS). The metal in the compound here is Copper (II) nitrate where as the metal trying to displace is silver. Silver lies below the copper in a ECS, that means Copper is more reactive than silver. The reaction is not possible because more reactive metal displaces less reactive metal from its compound, and silver is LESS reactive than copper so it cant displace the copper from copper nitrate.

Answer:
Fluoride is commonly used in dentistry to strengthen enamel, which is the outer layer of your teeth. Fluoride helps to prevent cavities. Fluoride also helps stop the decay process and prevent tooth decay.
Explanation:
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.

They have different number of Neutrons and protons, so their masses are different
Hope this helps!
