At 500 K, for the reaction: $$ \text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g) $$ Given: $ K_p = 0.036\, \text{atm}^{-2} $, $ R = 0.082\, \text{L atm mol}^{-1}\text{K}^{-1} $.Find $ K_c $ in $ \text{L}^2 \text{mol}^{-2} $.
In the Lewis dot structure of carbonate ion ($ \text{CO}_3^{2-} $), what are the formal charges on oxygen atoms 1, 2, and 3 respectively?
