Answer:
c. AgNO₃(aq) + NH₄Cl(aq) ->AgCl(s) + NH₄NO₃(aq)
Explanation:
We have to follow the <u>solubility rules</u> to check the states of each compound.
-) All the cholride salts are soluble EXCEPT those also containing: lead, silver or mercury. 
-) All the nitrate 
and ammonium salts 
are soluble.
With this in mind 
, 
and 
would be soluble, so we have to use the <u>aqueosus state (aq).</u>
The 
then would have a <u>solid state (s)</u>.
The equilibrium constant, represented as a variable K, is the ratio of the concentration of the products to the reactants which are raised respectively to their stoichiometric coefficients. Note that only substances in the aqueous phases are accounted. From the reaction given, K is equal to
<em>K = [Sn²⁺]³/[Fe³⁺]²</em>
Once you know the equilibrium concentration of Sn²⁺ and Fe³⁺ in molarity, just substitute them into the equation to solve for K.
Answer:
C7H6O+8O2 ---> 7CO2+3H2O
Explanation:
number of atoms of each element must be equal in both sides
