A 3.24-gram sample of NaHCO, was completely decomposed in an experiment. 2NaHCO3-Na2CO3 + H2CO3
In this experiment, carbon dioxide and water vapors combine to form H2CO3. After decomposition, the Na, COhad a mass of 2.19 grams.
A. Determine the mass of the H2CO, produced.
B. Calculate the percentage yield of H2CO3 for the reaction Show your work or describe the calculation process in detail.

2b2t

explanation:

2b2t

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

the answer is c.the valence of the atoms combine .

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
