Which balanced equation represents a redox
reaction?
(1) cuco3(s) ==> cuo(s) + co2(g)
(2) 2kclo3(s)==> 2kcl(s) + 3o2(g)
(3) agno3(aq) + kcl(aq) ==> agcl(s) + kno3(aq)
(4) h2so4(aq) + 2koh(aq)==> k2so4(aq) + 2h2o(l)

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
