A 3.24 gram sample of NaHCO3 was completely decomposed in an experiment. 2NaHCO3 -> Na2CO3 + H2CO3

In this experiment, carbon dioxide and water vapors combine to form H2CO3. After decomposition, the Na2CO3 had a mass of 2.19 grams.

Determine the mass of the H2CO3 produced. Calculate the percentage yield of H2CO3 for the reaction. Show your work or describe the process in detail.

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt

How do you calculate the mass of a product when the amounts of more than one reactant are given?

The table below shows a comparison of the different gas laws. some cells have been left blank. name variables constants equation boyle's law pressure, volume ? pv = k charles’s law volume, temperature ? v = kt ? temperature, pressure volume, moles of gas p = kt ? pressure, temperature, volume ? which are assumed to be constant while using the combined gas law? 1. pressure 2. number of moles 3. volume and moles of gas 4. pressure and temperature
