Consider the following reaction: A (g) + B (g) ⇌ 2 C (g) + D (g)
A reaction mixture initially contains 1.1 M A and 1.0 M B. If the equilibrium concentration of C is 0.75 M, what is the value of the equilibrium constant (Kc) for the reaction?

Can someone me with 1 to 4 plz. fast

What is the polyatamic ion of borate

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
