Use the following information S(s)+O2(g)→SO2(g)S(s)+O2(g)→SO2(g), ΔH∘ΔH∘ = -296.8kJkJ SO2(g)+12O2(g)→SO3(g)SO2(g)+12O2(g) →SO3(g) , ΔH∘ΔH∘ = -98.9kJkJ to calculate ΔH∘fΔHf∘ for H2SO4(aq)H2SO4(aq) (in kilojoules per mole). [For H2O(l),ΔH∘fH2O(l),ΔHf∘ = -285.8kJ/molkJ/mol]. Express your answer using four significant figures

All motion is caused by force? true or false

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
