Question

Write net equations for the spontaneous redox reactions that occur during the following or none if there is no extensive reaction. Instructions: Enter all substances in the order listed at the top of the column. Use a carot to indicate a superscript, but do nothing for subscripts. Use a hyphen + greater than (->) for yields. Click on the eye symbol to check your formatting. Reactants Rxn: Ox(1) + Red(2) + other -> Red(1) + Ox(2) + other

Manganese metal is added to a MgSO4 solution none

Chromium metal is placed in hydrochloric acid

A copper wire is added to nitric acid

Sodium metal is added to water

Potassium bromide is dissolved in an acidified solution of KMnO4

Explanation / Answer

Hi, I guess the instructions are from some website that will convert these characters into proper equations. However, as per the instructions I will type equations in the format provided.

Well Manganese put in MgSO4 solution will produce nothing since Mg2+ ions cannot oxidize Mn metal because Mn has a greater reduction potential.

chromium metal is oxidized to Cr2+ ions in hydrochloric acid.

2H^+ + Cr -> H2 + Cr^2+

copper metal is oxidized to Cu^2+ ions in nitric acid.

2 NO3^- + Cu + 4 H^+-> 2 NO2 + Cu^2+ + 2 H2O

sodium metal is oxidized to Na^+ ions and hydrogen is produced

2 H+ + 2Na -> H2 + 2Na^+

Potassium bromide is oxidized to Br2 and MnO4^- is reduced to Mn2^+

2MnO4^1- + 10Br^1- + 16H^1+ -> 2Mn^2+ + 5Br2 + 8H20

You asked for net equations, so here they are. If you need complete equation, just post a comment and I will write complete equations for you.
