Answer:
A) The Al(s)
B) The Ni2+(aq)
C) The Cu2+
D) The Zn(s)
Explanation:
A) The Al(s) is the species that is being oxidized given that it is the one with the highest oxidation potential in the solution.
B) The Ni2+(aq) is the species that is being reduced given that it is the one with the highest reduction potential in the beaker.
C) The oxidizing agent is the substance that is being reduced or you can say the one that has the potential to oxidite other substance. In this case the agent is Cu2+ given that it reduces itself while oxidates the lead.
D) The metal added needs to have a reduction potential lower than the H+ in order to form the gas. The only listed that meets the requirement is the Zn(s).
Answer:
ALL of these are factors in conservation.
Explanation:
Answer:
The 1st law of thermodynamics and the 2nd law of themodynamics
Explanation:
The first law of thermodynamics describes the conservation of energy. It states that when heat is added to a system, it transforms to an equal amount of another form of energy. It does this by doing one or both of the following things: (1) increasing the amount of internal energy within the system; and/or (2) doing external work by leaving the system, thereby affecting the area around the system.
The second law of thermodynamics states that no reaction is completely efficient and that heat is always transferred from warmer objects to colder objects. In other words, some energy is always lost to heat in any reaction, and you'll never find heat moving from colder objects to warmer objects in a system
Answer:
The water molecules turned into gas called<em> "water vapor"</em> and are now part of the air.
Explanation:
The "drops of water" are actually made up of<u> water molecules.</u> Under <em>heat,</em> they change their phase from liquid to gas. This means that the water molecules <em>move faster. </em>Such movement allows the molecules to escape into the atmosphere as gas. Such gaseous state of water is called "water vapor" <em>(transparent in color).</em>
The client consultation must have taken time that the drops of water evaporated when Jayden came back.
Aside from evaporation, water vapor may also be produced through the process called "sublimation." This happens when<em> ice directly turns into gas without becoming a liquid.</em>
So, this explains the answer.
