I need half reactions, for the following equation.

zhuklara [117]

Answer : Half reaction is defined as the reaction which will be either the oxidation or reduction reaction of particular species in a given redox reaction.

So as per the definition in the reaction of,

 $Ba + ZnSO_{4} ----\ \textgreater \ BaSO_{4} + Zn$

 $Ba_{(s)} + Zn ^{+2} + SO_{4}^{-2} = Ba^{+2} + SO_{4}^{-2} + Zn_{(s)}$

here on left and right side $SO_{4}^{-2}$ will get cancelled.

and we will get, $Ba_{(s)} + Zn ^{+2} = Ba^{+2} + Zn_{(s)}$

Here,
$Ba_{(s)} ----\ \textgreater \ Ba^{+2} - 2e^{-}$ ...this is oxidation reaction as Ba is getting reduced to $Ba^{+2}$ by losing 2 electrons.

whereas,on the other hand, $Zn ^{+2} ----\ \textgreater \ Zn_{(s)} + 2e ^{-}$ ...this is reduction reaction as $Zn ^{+2}$ is getting reduced to Zn by gaining 2 electrons.

what is the difference between the number of electrons in an atom of selenium, Se and the number of electrons in an atom of alum

ELEN [110]

Answer:

Well, electrons can be converted into a atomic number so if SE atomic number is 34 that means it has 34 electrons. AI has a atomic number of 13 meaning it has 13 electrons. So the difference is that SE has more electrons then AI.

Answer:

Exergonic

Explanation:

The process is exergonic because it transfer energy from the system to the surrounds in the shape of light. It happens because of the Gibbs free energy (ΔG) which is lower than zero. If the reaction was Endergonic, the Gibbs free energy should be higher than zero. We can calculate it from the GIbbs-Helmholtz equation: ΔG = ΔH - T . ΔS. ΔH is enthalpy, T is the temperature and ΔS is entropy.
