For the reaction given below, answer the questions relating to mole ratio. Put your answers on the lines. This is called Stoichiometry!
11. 2 H256) + 3 O2(g) → 2 SO2(9) + 2 H2O)
a) If 4.00 moles of oxygen react with an excess of hydrogen sulfide, how many moles
of sulfur dioxide will be produced?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

When a scientific theory has been tested and proved by the scientific community, it becomes a law
