Did an oxidation-reduction reaction occur in the reaction between copper sulfate and sodium sulfide? cuso4 + na2s → cus + na2so4 a. this is a redox reaction because copper gained electrons. b. this is a redox reaction because sodium lost electrons. c. this is a redox reaction because sulfur gained electrons. d. this is not a redox reaction because no electrons were transferred. e. this is not a redox reaction because oxygen did not gain electrons. in which reaction is precipitation occurring? a. mgcl2(aq) + cuso4(aq) → cucl2(aq) + mgso4(aq) b. cdso4(aq) + k2s(aq) → cds(s) + k2so4(aq) c. naoh(aq) + nh4cl(aq) → nacl(aq) + nh4oh(aq) d. k2so4(aq) + naoh(aq) → k2oh(aq) + naso4(aq) e. hno3(aq) + koh(aq) → kno3(aq) + h2o(l)
