Question

Assign oxidation state to each atom in each element ion or compound.

Answer 1

Answer:

a. $Ag^0$

b. $Ag^{+}$

c. $Ca^{2+}F_2^-$

d. $H_2^+S^{2-}$

e. $(C^{4+}O_3^{2-})^{-}$

f. $(Cr^{6+}O_4^{2-})^{2-}$

g. $Cl_2^0$

h. $Fe^0$

i. $Cu^{2+}Cl_2^-$

j. $C^{4-}H_4^+$

Explanation:

Hello there!

In this case, according to the concept of charge balance, which tell us that the overall charge is zero for any compound, except ions, it turns out possible to proceed as follows:

a. $Ag^0$

b. $Ag^{+}$

c. $Ca^{2+}F_2^-$

d. $H_2^+S^{2-}$

e. $(C^{4+}O_3^{2-})^{-}$

f. $(Cr^{6+}O_4^{2-})^{2-}$

g. $Cl_2^0$

h. $Fe^0$

i. $Cu^{2+}Cl_2^-$

j. $C^{4-}H_4^+$

Keep in mind lonely elements have 0 as their oxidation state.

Regards!
