A 3.81-gram sample of NaHCO 3 was completely decomposed in an experiment. 2NaHCO 3 Na 2 CO 3 +H 2 CO 3 In this experiment, carbon dioxide and water vapors combine to form H 2 CO 3 . After decomposition, the Na 2 CO 3 had a mass of 2.86 grams. Determine the mass of the H 2 OO 3 produced . B. Calculate the percentage yield of H 2 CO 3 for the reaction Show your work or describe the calculation process in detail.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

b. examine and describe cells
