why zinc extracted from zinc oxide through reduction with co?Ans) Reducing agent should have more negative ΔG value. In case of zinc oxide ,Zn has more negative ΔG value then CO as you can see from ellingham diagram, so it can not be reduced by CO.
(a) Using Lewis structures to describe your reasoning, describe why the following ions have different bond angles: ClO2 - and NO2 - (b) Given that the spatial arrangement of a

The radius of the nucleus is related to the mass number A by : (1 )R= R 0 A 1/2 (2) R= R 0 A (3) R= R 0 A 2
Entropy (S) is a molecular 'disorder', or more precisely 'the number of microscopic arrangements of energy possible in a macroscopic sample'. Entropy depends strongly on the state
Beginning in the early nineteenth century, scientists developed models to explain the structure of the atom. As more information was discovered about the nature of the subatomic pa
We all know that the reducing agent must have more negative ?G value. So, in the case of zinc oxide ,Zn has more negative ?G value then CO.
