How does the volume increase twice when the gas of 101.3 is changed to 50.65
Sulfuric acid, H2SO4 (MM = 98.08 g/mol) reacts with ammonia, NH3
(MM = 17.03 g/mol) to produce the fertilizer ammonium sulfate,
(NH4)2SO4 (MM = 132.15 g/mol). The reaction is:
H2SO4 + 2NH3 → (NH4)2SO4
a.) What is the mass of ammonia, NH3 needed to completely
react with 3 grams sulfuric acid, H2SO4?
b.) How many moles of ammonia is required to react with excess
sulfuric acid, H2SO4 to produced 1.4 grams ammonium
sulfate, (NH3)2SO4?
What is the purpose of starting with the temperature of the water lower than room temperature and ending about the same amount above room temperature?
Determine the size of this effect and, along with your percent error from above, estimate your overall uncertainty. If your values for lead and/or aluminum are not within your uncertainty of the accepted value, offer plausible explanations for what might account for the difference?
