Hydrogen gas and oxygen gas are reacted together as shown below to produce water. Calculate the maximum theoretical yield of water if 40g of hydrogen is used and then use your answer to work out the percentage yield if the reaction actually produces 234g of water. You may need some of the data below.

Electric charge is what ? a. kinetic energy b. radiation c. discovery d. electricity

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

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.
