A redox reduction can also be called?

Question

A. Combination reaction
B. Single replacement reaction
C. decomposition reaction
D. More than one response is correct

Answer 1

A. Combination reaction

Answer 2

the answer is D. more than 1.

in fact, all single replacements are redoxes. the element (which has a charge of 0) turns into an ion, and the thing that was originally an ion becomes an element.

in a decomposition, u could have a redox. for example:

2H2O--> 2H2 + O2

in the water, H has a charge of +1, and O has a charge of -2. now, there are both elements and have a charge of 0.

same thing goes for a composition reaction. look at the above rxn backwards.

2H2 + O2 -->2H20

two elements charged 0 are now both have charges.

Answer 3

A. A combination reaction is a redox reaction, but not all redox reactions can be called combinations. 2Sb + 3I2 ===> 2SbI3. Sb gets oxidized; iodine is reduced.

B. A single replacement reaction is a redox reaction, but single replacement is not another name for redox reaction. CuSO4(aq) + Zn(s) ===> Cu(s) + ZnSO4(aq)

C. Decomposition reactions can be redox reactions, but not all decompositions are. 2HgO(s) ===> 2Hg(l) + O2(g) is redox, but 2NaHCO3(s) ===> Na2CO3(s) + CO2(g) + H2O(g) is not.

D. I think none of the responses is correct.

Answer 4

I believe it would be D, even if its not entirely correct.
