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
Answer:
The comparison is between Fuel canister (diethylene glycol) or Tea candle (paraffin)
The answer is tea candle( paraffin)
Explanation:
A fuel’s efficiency is based on its reaction with air(oxygen). It is said to be efficient when it burns well when exposed to air(oxygen).
Tea candle( paraffin) burns more efficiently in the presence of oxygen when compared to fuel canister( diethylene glycol) due to the hydrogen bonds in the molecules of fuel canister( diethylene glycol) making it more stable and having a lesser affinity to air (oxygen) than those of tea candle (paraffin).
CHEMICAL ENERGY
Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.
Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, food, gasoline, and oxygen gas.
