ACE
Explanation:
Defined skill set: When we say advantages it is seen that it can be visualized during the early stages of one’s career.
Upward growth: Having a specific skill or being specialized in that work would also bring growth in that division. ...
Good package: A job specialization means a person is knowing how to do that work and complete it.
Answer: Mass of silver deposited at the cathode is 37.1g
Explanation: According to Faraday Law of Electrolysis, the mass of substance deposited at the electrode (cathode or anode) is directly proportional to quantity of electricity passed through the electrolyte
Faraday has found that to liberate one gm eq. of substance from an electrolyte, 96500C of electricity is required.
+e− ==> Ag(s)
Given that
Current (I) = 8.5A
Time (t) = 65 *60 = 3900s
Quantity of electricity passed = 8.5*3900 =33150C
Molar mass of Ag= 108g
96500C will liberate 108g
33150C will liberate Xg
Xg= (108*33150)/96500
=37.1g
Therefore the mass of Ag deposited at the cathode is 37.1g.
Answer:
energy is used to break bonds in reactants and energy is released when new bonds form in products.The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy there is no overall change in the amount of energy during the reaction.

Answer:
Analyzing data and drawing conclusions
Explanation:
The scientific method is a process or method of inquiry that follows a series of sequential steps which helps a scientist to understand the world around him, draw conclusions and predict results.
The steps in the scientific method include:
1. Observation: the scientist observes his environment keenly and carefully.
2. Asking a question to identify the problem.
3. Conducting research to get information about the problem.
4. Making a hypothesis or an educated guess of a possible outcome.
5.Conducting experiments to test the hypothesis.
6. Analyzing data and drawing conclusions: this involves drawing inferences about experimental results and determining if the collected data supports the original hypothesis and determining if the hypothesis is correct.
7. Communicate results: presenting the result and data through various media, such a laboratory report.
