What is the balanced chemical equation for the complete reaction between CO32- and HCl?Between KHP and NaOH? SHOW THE NET IONIC EQUATIONS.

2H+ +CO32-   H20+CO2

KHP+OH- KP +H2O

Explanation:

2HCl(aq) + CO3 2-(aq) ---> H2O(l) + CO2(g) + 2Cl-(aq)

In the reaction intermediate carbonic acid is formed which gets dissociated into CO2 and H2O

2HCL+CO32CO2+H20+2Cl-

ionic equation

2H+ +CO32-   H20+CO2

Reaction between KHP and NaOH

KHP+NaOH NaKP+ H2O

ionic reaction equation

KHP+OH- KP +H2O

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.

the answer would be b i believe
