An electrochemical cell is made up of an Zn2+/Zn half-cell and an Ag+/Ag half-cell. If the mass deposited at the silver electrode is 0.50 g, calculate the mass lost at the zinc electrode.​

Check the correct box to describe the periodic trends in electronegativity. electronegativity across a period: decreases. increases. electronegativity down a group: decreases. increases.

What is the overall order of reaction for rate = k[no]2[o2]

13. a covalent bond between two atoms is likely to be polar if: a. one of the atoms is much more electronegative than the other. b. the two atoms are equally electronegative. c. the two atoms are of the same element. d. the bond is part of a tetrahedrally shaped molecule. e. one atom is an anion.
