Samples of hydrated manganese perchlorate are heated to determine the amount of crystal water:Mn(ClO4)2·nH2O ! Mn(ClO4)2 + nH2OTwo samples of different weight are studied:a) m (before heating) = 1.629 g ; m (after heating) = 1.142 gb) m (before heating) = 9.048 g ; m (after heating) = 6.645 gFor both samples, calculate the number of moles of crystal waterper formula unit of manganese perchlorate. Decide which sample is most likely to represent the correct result, and explain what might have gone wrong with the other.
What is the number of milligrams of Ag+ that is not precipitated? Also, if the AgCl precipitate is washed with 200.00 mL of water, what is the maximum number of milligrams of AgCl that could be lost

Sodium will react with oxygen to form sodium oxide. Use the formula below to determine how many grams of sodium oxide will be formed if 46 grams of sodium are used in the reaction. 4Na + O2 --2Na2O
The chemical formula for caffeine is C8H10N4O2. Define how many grams of carbon are present in a 12.46 gram sample of caffeine
Chlorine is more reactive than bromine. Bromine can be prepared by adding chlorine to an aqueous solution of sodium bromide. The reaction is represented by the equation 2 NaBr(aq) + Cl2(g) = Br2(l) + 2 NaCl(aq)
