3 Mn3O4(s) + 8 Al(s) → 4 Al2O3(s) + 9 Mn(s)
How many manganese atoms are released if 54.8 moles of Mn3O4 react with excess aluminum.
A 0.784-g sample of an alloy containing Al and Mg is dissolved and treated to prevent interferences by the alloy’s other constituents. Aluminum and magnesium are precipitated, providing a mixed precipitate of Al(C9H6NO)3 and Mg(C9H6NO)2 that weighs 8.215 g. Igniting the precipitate converts it to a mixture of Al2O3 and MgO that weighs 0.932 g. Calculate the %w/w Al and %w/w Mg in the alloy.
A modern digital barometer says that atmospheric pressure is 101.293 kPa and the height of mercury in the barometer is 762.79 mm as shown. What is the absolute pressure of the gas in the bulb of this barometer (in Pa)? [The density of mercury at this temperature is 13534 kg m−3 . In this problem use g = 9.807 m s−2 .]
