Why is carbon ideal for making different compounds?

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %
