A. Theresa is going to be my girl this year, he promised himself as he left the gym full of students in his new fall clothes.
I believe it is B... because all balance equation are supposed to follow the law of conservation of mass
It also depends on what we use to make the energy in the power plants. Many use uranium which is non renewable. A better alternative would be wind or solar as it is always around. Hope this helps.
Ionic substances formed from complete transfer of electrons from one atom to another causing electrostatic attraction
Answer:
Ecel =0,04 V
Explanation:
Apply the Nerst equation,
Ecel= Ecelº - (RT/nF)*lnQ
where R=8,314 J/molK, T=25ºC=298K and F =96 485 Coulombs/mol e- and n=number of moles of electrons transferred in the balanced equation. Q is cocient of products and reactives power to respective coefficients, if is a gas apply partial pressure
Write the semiequation redox and verify the numbers of electron for balance. In this case you don't need to change nothing
2Cl−(aq)→Cl2(g) + 2e-
<u>2CO3+(aq) + 2e-→2CO2+(aq)</u>
2Cl−(aq) + <u>2CO3+(aq) </u>→<u>2CO2+(aq) + </u>Cl2(g)
Hence
Ecel= 0.483 V - 0.013Ln ([CO2+]^2*PCl2] / [CO3+]^2*[Cl-]^2)
Ecel= 0.483 V - 0.013Ln ([0.205]^2 * 7.3] / [0.19]^2*[0.144]^2)
Ecel =0,04 V
