With further testing, Julia discovers McInnes was suffering from ocular syphilis. 230 °C decomposition to arsenic and hydrogen is rapid.

Zinc arsenide and sodium arsenide are suitable precursors:[10]. For example, As(C6H5)3, called triphenylarsine, is referred to as "an arsine".

[citation needed], It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. The term arsine is commonly used to describe a class of organoarsenic compounds of the formula AsH3−xRx, where R = aryl or alkyl. Brittany Bennett as Enid McInnes 2007[18]). While shooting in Guelph during a karaoke break, ". Related to phosphorus, arsenic is an n-dopant for silicon and germanium. Some of her formulas are very sophisticated and she had been using rats as test subjects with some success. ⋅ Die Aufgaben selbst stellen zum Teil einfache Fragen und Probleme des Alltags dar. The insidious disease may have played a role in Mr. McInnes' death.

Alternatively, sources of As3− react with protonic reagents to also produce this gas. Allerdings werden PISA-Tests nicht unter ausreichend abgesicherten Bedingungen durchgeführt, so dass die Ergebnisse in der Regel nicht für eine Intelligenzaussage zu den einzelnen Schülern verwendet werden können. [34] Durch diese willkürliche Zerlegung von Intelligenz in „Fähigkeit und Äußerung derselben“ werde aus den vom Test behaupteten, sorgfältig ausgedachten Kriterien für das Konstrukt Intelligenz ein Messinstrument für die Intelligenz.

Der Psychologe und Erziehungswissenschaftler Howard Gardner kritisierte, es gebe viele Dinge, die durch den IQ nicht erfasst und erklärt würden. Continuing the analogy to SbH3, AsH3 is readily oxidized by concentrated O2 or the dilute O2 concentration in air: Arsine will react violently in presence of strong oxidizing agents, such as potassium permanganate, sodium hypochlorite, or nitric acid.
