Balance these chemical equations?

Question

NH3 + HCL ----> NCL + H

AgNO3 + HCL -----> AgCl + HNO3

Answer 1

NH3 + HCl===>NH4Cl

AgNO3 + HCl===>AgCl + HNO3

They're balanced.  

Answer 2

To balance the equation here are the steps:

a. list all the ions forming the reactions then write the number of atoms (subscripts)

reactant                                  product

N=1                                           N=1

H=4                                           H=1

Cl=1                                          Cl=1

the number of Hydrogen (H) is not balanced so next step

b. choose coefficient(whole numbers)

NH3 + HCl-----> NCl +4 H

I have used 4 as a coefficient to balnce the equation.

Do the same with the other reaction

AgNO3 + HCl ----> AgCl + HNO3 -- is already a balanced equation

--------------------------------------...

That's my answer and I am a hundered percent sure.

although, not to argue with the one who posted this question but, are you sure that your given equations are correct?

In the first equation, i know you have used double replacement reaction. However the hydrogen (H)in the product side must have a subscript 2. (hydrogen is diatomic)

so:

NH3 + HCl ----> NCl + H2 in this case, NH3 + HCl----> NCl + 2H2 is the real balanced equation of this reaction. =)

Answer 3

NH3 +  HCl   =   NH4Cl

AgNO3  +  HCL  =  AgCL  + HNO3

Answer 4

NH3 + HCL ---->  NH4Cl

AgNO3 + HCL -----> AgCl + HNO3
