When a solid is dissolved in a liquid, the vapor pressure of the liquid is because the surface area from which molecules can evaporate
is reduced. (increased/decreased)

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

Answer///precipitate;
