It conforms what ever surface its in.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

Answer:

5.6⋅10−^19  j

do you need the explaination?

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
