why is carbon monoxide used to reduce zinc oxide to zinc in the zinc extraction process and not carbon directly?

The chemical reaction involving the reduction of ZnO by CO is not feasible thermodynamically: This is because the standard free energy of formation ( ) of CO2 from CO is higher than that of the formation of ZnO from Zn. Thus, CO cannot be used to reduce ZnO to Zn.

2b2t

explanation:

2b2t

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
