If you were to combine a 200.0mL aqueous solution of 0.75M NaHCO3 with 200.0mL of 0.50M CaCl2 in a constant pressure calorimeter, what change in temperature would you measure?
How many grams of magnesium chloride could be formed from the reaction of 6.82 g of magnesium with excess HCl?
A sample containing NaCl, Na2SO4, and NaNO3 gives the following elemental analysis: Na: 35.315%, O: 36.55%; Cl: 15.17%. Calculate the mass percent of each compound in the sample.
The mixture was stirred, causing all of the sample to dissolve. The excess HCl in the solution required 38.4 mL of 0.164 M NaOH for complete neutralization in a titration. What was the molecular formula of the white substance
