The net force on a vehicle that is accelerating at a rate of 1.5 m/s2 is 1,800 newtons. What is the mass of the vehicle to the nearest kilogram?

Yeah, but what are you trying to ask?

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

Ithink the answer is d.
