Which of the following statements concerning molecular orbital (MO) theory are correct? I. The Pauli Exclusion Principle is obeyed. II. Hund's rule is obeyed. III. a bonding molecular orbital is lower in energy than its parent atomic orbitals IV. the combination of two atomic orbitals creates one molecular orbital V. an antibonding molecular orbital is lower in energy than its parent atomic orbitals

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the answer is 0.8m.
