A 2.36-gram sample of NaHCO, was completely decomposed in an experiment. 2NaHCO3-Na2CO, + H2CO3
In this experiment carbon dioxide and water vapors combine to form H2CO3. After decomposition the Na2C0s had a mass of 1.57 grams.
A. Determine the mass of the H2CO, produced
B. Calculate the percentage yield of H. CO, for the reaction. Show your work or describe the calculation process in detail.

i dont know

explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

c. orbital shape i hope this is correct
