Sodium carbonate is a reagent that may be used to standardize acids. In such a standardization it was found that a 0.498-g sample of sodium carbonate required 23.5mL of a sulfuric acid solution to reach the end point for the reaction.

Na2CO3 (aq) + H2SO4 (aq) ---> H2O (l) + CO2 (g) + Na2SO4 (aq)

What is the molarity of the H2SO4?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt
