Two positively charged sphoros, each with a charge of 1x10C, with a mass of 10 kg, and separated by a distance of 14 cm, are hold in place on a frictionless track. What is the electrostatic potential energy of this system?

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

Its the second one nonmetals are moldable and easily shaped
