A 1.733 g sample of a metal reacts with hydrochloric acid to form a MCl2 type of salt and 380.0 mL of H2 at 20 degrees C and 720 torr pressure. a) Write a balanced net ionic equation for this reaction b) Determine identity of the metal.
question given the following heat capacities assume they are constant over the temperature range in consideration here
Which process would have a entropy greater than 0. a. n2(g)+3H2(g) = 2nh3(g) b. ch4(g) + h2o(g) = co(g) + 3h2(g) I believe it's b. because the molar masses of the products are similar so I would say that b. has more complex species so it's entropy..
