Compound ΔG∘f (kJ/mol) A +387.7 B +550.7 C +402.0 Use the data given here to calculate the values of ΔG∘rxn at 25 ∘ C for the reaction described by the equation A+B↽−−⇀C If ΔH∘rxn and ΔS∘rxn are both negative values, what drives the spontaneous reaction and in what direction at standard conditions? ΔG∘rxn= kJ The spontaneous reaction is enthalpy-driven to the left. enthalpy-driven to the right. entropy-driven to the right. entropy-driven to the left.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

answer is: empirical formula is tl₂o. if we use 100 grams of compound, tha:

m(tl) = 96.2%  · 100 g ÷ 100%.

m(tl) = 96.2 g.

n(tl) = m(tl)  ÷ m(tl). n(tl) = 96.2 g  ÷ 204.4 g/mol.

n(tl) = 0.47 mol. m(o) = 3.77 g. n(o) = m(o)  ÷ m(o). n(o) = 3.77 g  ÷ 16 g/mol. n(ag) = 0.235 mol. n(tl) . n(o) = 0.47 mol : 0.235 mol /0.235. n(tl) . n(o) = 2 : 1.

m(tl₂o) = 204.4 g/mol  · 2 + 16 g/mol = 424.8 g/mol.

m(compound) = 456. 8 g/mol - 424.8 g/mol = 32 g/mol ( 2 oxygens); tl₂o₃.
