Given the balanced equation representing a reaction:
2H2 + O2 = 2H2O
What is the total mass of oxygen That must react with 8 grams of hydrogen to for 72 grams of water?
(1) 8 g (3) 64 g
(2) 36 g (4) 80 g

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

the ratio of the conjugate base to the acid required to attain the desired ph.
