Consider an ionic compound, mx2, composed of generic metal m and generic, gaseous halogen x.
the enthalpy of formation of mx2 is δhf° = –799 kj/mol.
the enthalpy of sublimation of m is δhsub = 157 kj/mol.
the first and second ionization energies of m are ie1 = 785 kj/mol and ie2 = 1451 kj/mol. the electron affinity of x is δhea = –349 kj/mol.
the bond energy of x2 is be = 157 kj/mol. determine the lattice energy of mx2.

Afamily is one another name for a group on the table of elements.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
