The reaction that represents the standard enthalpy of formation for sucrose (C12H22O11) is: a. C12H22O11(s) + 12 O2 ? 12 CO2(g) + 11 H2O(g)
b. 12 C(diamond) + 11 H2(g) + 11/2 O2(g) ? C12H22O11(s)
c. 12 C(graphite) + 11 H2(g) + 11/2 O2(g) ?C12H22O11(s)
d. 24 C(diamond) + 22 H2(g) + 11 O2(g) ? 2 C12H22O11(s)
e. C12H22O11(s) ?12 C(graphite) + 11 H2(g) + 11/2 O2(g)

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

If you are told to get 100 ml of stock solution to use to prepare smaller size sample for an experiment, which piece of glassware would you use?
