Why do you think lone pairs of electrons create greater repulsion when located near other lone pairs or bonding pairs? Orbitals containing lone pairs of electrons require more space
than orbitals containing bonding pairs. Why do you think this is the case? What does the
presence of one or more lone pairs of electrons do to the bond angles in a molecule (in other
words, do bond angles get larger, smaller, or remain unchanged?)

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
