hello. i need some help with my chemistry. can you please help me?
i am asked to identify which unknown compound was used for an experiment by using mass relationships. all the compounds are salts. i have succeeded in knowing that the substance is a hydrogen carbonate. i am now choosing between NaHCO3
. the problem is this:
Write the chemical equation for the overall reaction that would occur when the original compound
was converted to a chloride. If the compound is a hydrogen carbonate, use the sum of Equations
1 and 2. If the sample is a carbonate, use Equation 2. Write the equation for a sodium salt and
then for a potassium salt.
Equation 1 is ( for hydrogen carbonate, eg. NaHCO3(s)
Equation 2 is ( for carbonate, eg. Na2
+ 2 Cl(aq)
--> 2 NaCl(s)
O + CO2(g)
I do not know how to use the sum of equations 1 and 2 so i can write a chemical equation. please help. thanks a lot!
i'm thinking that i should combine all the equations, but i just don't know where to start. i tried having the left side of equation 1 be added with hydrogen and chlorine that will result to NaCl, Na2
, water, and carbon dioxide. is this correct?
