 Question: can you have a heart attack from laughing Context: Fractional oxidation states are often used to represent the average oxidation state of several atoms of the same element in a structure. For example, the formula of magnetite is Fe O , implying an average oxidation state for iron of +8/3. However, this average value may not be representative if the atoms are not equivalent. In a Fe O crystal below 120 K (−153 °C), two-thirds of the cations are Fe and one-third are Fe , and the formula may be more specifically represented as FeO Fe O .
 Question: can the oxidation state of an element be fractional Context: In general, ambulance squads are unable to contravene the wishes of a mentally competent patient. This may lead to situations of likely cardiac compromise, likely internal trauma, or other life-threatening situations. However, if the patient is of sound mind, they are generally able to refuse treatment. The EMS provider has limited options at this point, since EMS generally cannot restrain and take a person involuntarily. However, depending on local policy, the police may be able to place the patient in protective custody (essentially arresting the person and releasing them to the EMS agency). This option is not to be pursued lightly. This is typically termed the RMA-AMA (refusal of medical assistance against medical advice) to differentiate it from a standard RMA (which may be assumed to be the end to a trivial call)
