inessss [21]

Answer:

The standard cell potential of the reaction is 0.78 Volts.

Explanation:

Cu^{2+}(aq)+Fe(s)\rightarrow Cu(s)+Fe^{2+}(aq)

Reduction at cathode :

Cu^+(aq)+2e^-\rightarrow Cu(s)

Reduction potential of  Cu^{2+} to Cu=E^o_{1}=0.34 V

Oxidation at anode:

Fe(s)\rightarrow Fe^{2+}(aq)+2e^-

Reduction potential of  Fe^{2+} to Fe=E^o_{2}=-0.44 V

To calculate the E^o_{cell} of the reaction, we use the equation:

E^o_{cell}=E^o_{red,cathode}-E^o_{red,anode}

Putting values in above equation, we get:

E^o_{cell}=0.34V -(-0.44 V)=0.78 V

The standard cell potential of the reaction is 0.78 Volts.

How does the path of the moon in the sky vary throughout the year
Kay [80]

Answer: your answer

Explanation: The Moon follows generally the same path, but with some important differences. The Moon's orbit is tilted 5.1° relative to the ecliptic. So, the Moon can appear anywhere in a band extending 5.1° north (above) and south (below) of the ecliptic. Each month, the Moon twice crosses the ecliptic on opposite sides of Earth
