An aqueous solution of sodium hydroxide reacts completely with a solution of hydrochloric acid. after all the water evaporates from the reaction mixture, what will remain

This is acid-base reaction:

NaOH (aq) + HCl (aq) = H2O (l) + NaCl (aq)

After the water evaporated from reaction, NaCl (salt) remains.

a electronegativity decreases beacuse the size of nucleus is bigger.

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
