A potassium ion (K+) would most likely bond with .

Mg+
O
Cl-
Na+

Explain why scientists use shared characteristics to make cladograms.

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
