Answer:
ΔG° is negative and ΔE° is positive
Explanation:
A galvanic cell produces electrical energy from spontaneous electrochemical processes.
In a galvanic cell, ∆E° is always positive since the reaction is spontaneous at room temperature.
Generally in thermodynamics, a negative value of ∆G shows a spontaneous chemical process. Hence in a galvanic cell, ΔG° is negative and ΔE° is positive.
The answer would be C. hope this helped.
We know that as we move from left to right across a period in a modern periodic table, electronegativity increases ( i.e., gaining of electrons from an atom ). So Magnesium(Mg) who has an atomic no. as 12 will not gain electrons but share/transfer electrons to Neon(Ne).
I hope this answer will help you...If it does then mark my answer as the brainliest!!!
Byee!!!
Answer: C) Bent or angular, polar
Explanation:
The central atom oxygen has two lone pairs and two bond pairs in . The number of electron pairs are 4, that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral. But as there are two lone pair of atoms around the central oxygen atom, repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent shape.
The compound is polar as the net dipole moment of oxygen - fluoride bonds do not cancel each other out.
