@X@user.full_name@X@ @GMU: What is the standard cell voltage at 25.0oC for the reaction below?Cr3+(aq) + Al(s) → Cr(s) + Al3+(aq) K = 3.75e39

@X@user.full_name@X@ @GMU: From the reaction below, calculate the free energy of formation for C9H18(g) at 25°C, if ΔGfo(CH4(g)) is -50.790 kJ/mol.9CH4(g) → C9H18(g) + 9H2(g) ΔGo = 569.985 kJ/mol

@X@user.full_name@X@ @GMU: ACS-Using the given rate data what is the correct rate law for the reaction below?NO2 + CO⇋ CO2 + NO  Exp [NO2]o [CO]o Initial Rates, Ms-1 1 0.167 0.167 5.86e-9 2 0.334 0.167 1.17e-8 3 0.334 0.242 1.70e-8

@X@user.full_name@X@ @GMU: What is the correct name for FeBr3?

@X@user.full_name@X@ @GMU: Closed-tube manometers work exactly as barometers except by connecting them to a container its pressure can be measured. Assume you have a closed-ended manometer filled with an oil having a density of 0.7722 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure if the height of the oil column is 1094.62 cm?

@X@user.full_name@X@ @GMU: What is the mass (grams) of one atom of gold?
