Answer:
The standard cell potential is 2.00 V
Explanation:
<u>Step 1:</u> Data given
Cu is cathode because of
higher EP
Al3++3e−→Al E∘=−1.66 V anode
Cu2++2e−→Cu E∘=0.340 V cathode
<u>Step 2:</u> Balance both equations
2*(Al → Al3+-3e−) E∘=1.66 V
3*(Cu2++2e−→Cu) E∘=0.340 V
<u>Step 3:</u> The netto equation
2 Al + 3Cu2+ +6e- → 2Al3+ + 3Cu -6e-
2 Al + 3Cu2+ → 2Al3+ + 3Cu
<u>Step 4:</u> Calculate the standard cell potential
E∘cell = E∘cathode - E∘anode
E∘cell = E∘ Cu2+/Cu - E∘ Al3+/Al
E∘cell =0.340 V - (-1.66) = 2.00 V
The standard cell potential is 2.00 V
when an ionic or covalent compound is dissolved in water they break apart into ions through process called dissociation ..the ions get attracted by the water molecules and hence they carry polar charges ..and if there is a conduction of electricity. .then we get to know that a compound is dissociated ..

The nutrients that the body breaks down into basic units are carbohydrates, fats, and proteins. From carbohydrates comes glucose, your body's -- especially the brain's -- primary form of fuel; from fats we get glycerol and fatty acids, many of which are essential ingredients in hormones and the protective sheath in our brain that covers communicating neurons; and from proteins we get amino acids, which are the building blocks to lots of structures, including our blood, muscle, skin, organs, antibodies, hair, and fingernails.
Each of these nutrients travels down a different pathway, but all can eventually fuel the body's production of ATP (adenosine triphosphate), which is essentially our bodies' ultimate energy currency.
Observation : a piece of info we all gather through our 5 senses
Hypotheses: a testable explanation for an observation
Data: info that scientists gather during an experiment
Experiment: a procedure that is designed to test a hypothesis
Conclusion a judgment or decision
Scientific method a series of steps
well when there is more kinetic energy in a solution the higher its temperature is going to be so the more the molecules are able to be help together, the lower the temperature the more difficult it would be to break the molecule apart in order to bond with it.
