(chemistry , quick! worth 55 points) a 3.24-gram sample of nahco3 was completely decomposed in an experiment.
2nahco3 > naco3 + h2co3
in this experiment, carbon dioxide and water vapors combine to form h2co3. after decomposition, the na2co3 had a mass of 2.19 grams.

1. determine the mass of the h2co3 produced.
2. calculate the percentage yield of h2co3 for the reaction. make sure to show work, and describe the calculation process.

will mark as !

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

it is stable as it is in group 0 which have full outer shells of electrons

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
