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

Los isomeros ópticos
krek1111 [17]

Answer:

Los isómeros ópticos son dos compuestos que contienen el mismo número y tipo de átomos, y enlaces (es decir, la conectividad entre los átomos es la misma), y diferentes disposiciones espaciales de los átomos, pero que tienen imágenes especulares no superponibles. Cada estructura de imagen especular no superponible se denomina enantiómero.

What mass of NaOH is in 3.0e+02 mL of a 5.0 M NaOH solution?
Snezhnost [94]
Answer is: mass of sodium hydroxide is 60 grams.
V(NaOH) = 300 mL · 1 L/1000mL = 0,3 L.
c(NaOH) = 5 M = 5 mol/L.
n(NaOH) = c(NaOH) · V(NaOH).
n(NaOH) = 5 mol/L · 0,3 L.
n(NaOH) = 1,5 mol.
m(NaOH) = n(NaOH) · M(NaOH).
m(NaOH) = 1,5 mol · 40 g/mol.
m(NaOH) = 60 g.
