The element arsenic would be expected to form covalent bond(s) in order to obey the octet rule. Use the octet rule to predict the formula of the compound that would form between arsenic and hydrogen , if the molecule contains only one arsenic atom and only single bonds are formed. Formula: The compound ammonium chloride is a strong electrolyte. Write the reaction when solid ammonium chloride is put into water: + The compound sodium acetate is a strong electrolyte. Write...

Review Constants Periodic Tab Part A The gas-phase reaction of NO with F to form NOF and has an activation energy of E. = 6.30 kJ/mol and a frequency factor of A = 600-108 M. The reaction is believed to be bimolecular NO(s)+F2(g) NOF(g) + F(g) where NO is a free radical. Free radicals, species with an odd number of unbound electrons tend to be more reactive. This is one reason by NO reacts so readily with gases such as...
