Answer all questions using the correct number of significant figures and correct units. (a) Write the balanced molecular and ionic equations, indicating the state of each species in each equation, for the reaction between Mg(s) and HCl(aq): MOLECULAR: TOTAL IONIC: NET IONIC: (b) If 0.050 mol magnesium metal reacts with HCl(aq), how many moles of hydrogen gas are formed? Assume hydrogen to be an ideal gas. Using the definitions for decimeter (dm), centimeter (cm), and milliliter (mL), show that one-liter (L) is the same as one cubic decimeter (dm^3). Using the vapor pressure data on page 2 of the Introduction, plot a graph of the log of the vapor pressure of water, log p, on the ordinate against the reciprocal of the absolute temperature, 1/T, on the abcissa. Follow the guidelines in Experiment #1. Determine the vapor pressure of water at 22.2 degree C using (a) Numberical interpolation (b) Graphical method (c) Compare the values obtained by the two methods
