Determine the molecular formula for each molecule. A five carbon ring with two C H 3 groups attached to carbon atoms in the ring. molecular formula: C7H16 A six carbon ring with two C H 3 groups and a C H 2 C H 3 group attached to carbon atoms in the ring. molecular formula:

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.

Use the periodic table to determine how many grams of oxygen would be required to react completely with 859.0 g c2h2
