Consider these two entries from a fictional table of standard reduction potentials. X3++3e−⟶X(s)o=−1.95 V

Y3++3e−⟶Y(s)o=−0.19 V

What is the standard potential of a galvanic (voltaic) cell where X is the anode and Y is the cathode?

Which of the following observations indicates that an atom has neutrons? some uncharged particles are scattered by a beryllium atom when it hits a gold foil. some uncharged particles bounce back from a gold foil when it is bombarded with alpha particles. a radiation consisting of uncharged particles is emitted when alpha particles strike beryllium atoms. a radiation which attracts electrons is produced when a beryllium atom is bombarded with alpha particles.
