2.845 x 102 potassium ions (What is the chemical symbol of the potassium ion?) equals how many moles of potassium ions?

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

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; carbon monoxide (co);
