Use the standard reduction potentials to find the equilibrium constant for each of the following reactions at 25°c.
(a) 5 fe2+(aq) + mno4? (aq) + 8 h+(aq) < > mn2+(aq) + 4 h2o(l) + 5 fe3+(aq)
(b) 2 ce4+(aq) + 2 cl ? (aq) < > cl2(g) + 2 ce3+(aq)
(c) br2(l) + 2 i ? (aq) < > 2 br? (aq) + i2(s)

The correct answer is "atomic weight".

Bthats what im doing to and i figured it out it is b

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

The answer is tea due to the main ingredient being a herb that grows from the ground and sugar that grows from a stalk, i hope this : )     p.s.  can i be brainliest?
