Please complete these two reactions: 1)NaOH + HNO3 --> ..............................................?

1) NaOH + HNO3 >> NaNO3 + H2O

Na has a charge of 1+

OH has a charge of 1-

H has a charge of 1+

NO3 has a charge of 2-

when you combine these 2 equations the two with opposite charges will match up

Na will match up with NO3 and become Na2NO3 (the 2 in Na comes from the 2- charge of NO3, while NO3 receives the 1+ charge of Na)

OH will match up with H and become H2O (this is neutral becuase OH- and H+ charges cancel out)

NaOH + HNO3 <--> Na2NO3 + H2O

I must say BuBbLeS143 is quite mistaken. :/ NO3 has charge of -1, not -2. The first equation is an acid/base reaction, not equilibrium. (melovecheese gives the right equation)

2. involves two salts and an acid. A mixture of Na2SO4 and HCl, HI, may be formed. (Latter two might be in gaseous form, not too sure.)

NaOH(aq) + HNO3(aq) → NaNO3(aq) + H2O(l)

NaI + H2SO4 -----> NaHSO4 + HI(g)

further reactions-

8HI + H2SO4 -----> 4I2 +H2S + 4H2O

2HI + H2SO4 -----> SO2 + 2H2O + I2

NaCl + H2SO4 ------> NaHSO4 + HCL(g)
