For the following reactions
(a) zn(s) + cu2+(aq) → zn2+(aq) + cu(s)
(b) c12 h22 o11 (s) + 12 o2(g) → 12 co2(g) + 11 h2 o(l)
(i) calculate the standard reaction gibbs energies at 298 k.
(ii) use standard gibbs energies of formation from the data tables to calculate the standard reaction gibbs energies at 298 k. compare these values with those calculated in (i).

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.

The velocity would be 2
