The effective nuclear charge, ğeff , for a valence electron can be approximated using the core charge of the atom; that is, the total charge of the nucleus and the inner (nonvalence) electrons. determine the core charge for an atom of na.

High-energy and unstable.

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

The answer is tea due to the main ingredient being a herb that grows from the ground and sugar that grows from a stalk, i hope this : )     p.s.  can i be brainliest?
