Use line notation to represent the electrochemical cells for each of the following overall redox reactions.

2Ag+(aq)+Pb(s)→2Ag(s)+Pb2+(aq)
2ClO2(g)+2I−(aq)→2ClO−2(aq)+I2(s)
O2(g)+4H+(aq)+2Zn(s)→2H2O(l)+2Zn2+( aq)

Match the following items. 1. high-intensity bundle of energy being emitted from some decaying nuclei gamma ray 2. particle radiating from the nucleus of some atoms beta particle 3. negative particle identical to an electron but radiating from a decaying nucleus alpha particle

Which of the following observations indicates that there is a small, dense, positively charged part in the center of an atom? some uncharged particles are scattered by a gold foil. all uncharged particles are attracted towards a gold foil. all positively charged particles pass straight through a gold foil. some positively charged particles bounce back from a gold foil.

One way that radioactive waste is treated is by burying it in repositories. the repositories are found only in states with very low populations. true or false? a. trueb. false(also i meant to put high school but it put down middle school instead)
