Answer:

Oxidation  half  reaction  is  written   as    follows when  using  using  reduction potential  chart

example  when  using  copper  it is  written  as  follows

CU2+   +2e-  --> c(s)  +0.34v

oxidasation  is the  loos  of  electron  hence copper oxidation  potential  is  as  follows

cu (s)  -->  CU2+   +2e    -0.34v

Which pair consists of a molecular formula and its corresponding empirical formula?
MissTica
<span>3) P4O10 and P2O5
The mass of the P4O10 divided by the mass of the P2O5=2, and if you multiply the number of atoms in the P2O5 by 2, you get the P4O10, thus P2O5 is its empirical formula.</span>

Which of the following combination of elements would result in covalent compound? * W X Y Z Vand X Wand Z Y and Z Wand y​
TEA [102]

Answer:

C. Y & Z

Explanation:

V, W are imaginary metals here because their valence electrons are typically less than 4. X, Y, Z are non-metals and have higher valence electrons. Here, if V or W bind with X, Y, or Z we make ionic bond (because metal + non metal = ionic). But, if X binds with Y or Z or any combinations of any two of the three non-metals results in covalent bond (non metal + non metal = covalent).

Thus, Y and Z make covalent.
