The study of the reaction of water with the early first-row transition metal ions has been completed in this work, in both high- and low-spin states. In agreement with experimental observations, the only exothermic products are the low-lying states MO+ + H2; formation of other endothermic ...
model of reaction of the Au25L181− nanoparticle with metal ions, in which the Au25L181− nanoparticle acts as a reductant toward the metal ion, forming Au25M(SC2Ph)18 adducts that become oxidatively dissociated in the mass spectral cationization environment to yield the bimetals observed...
Metals have a range of reactivities – to illustrate this, you have to look no further than the classicalkali metals in water demonstrationcommonly used in chemistry classes. In this demonstration, small pieces of three different metals from group 1of the periodic table are dropped into a large...
For example, ruthenium(VI) bis-oxo porphyrin species epoxidize a large number of substrates in the presence of two-electron chemical oxidants, oxygen atom donors in particular. This type of reactivity should be investigated further with other platinum group metals, which are known to facilitate a...
Carbyne anions (R–C–) are one of the least explored and most poorly understood subvalent carbon species and, so far, have only been observed in the gas phase. In this study, we report the synthesis and isolation of copper phosphinocarbyne anion complex
There have been a number of investigations into the nature of these processes, and they are broadly categorized as parasitic and irreversible cathode-electrolyte reactions, trace moisture resulting in the dissolution of transition metals and interactions with electrolyte components, acidic attack on ...

reactive metal than copper. hence, iron corrodes in the presence of copper. while zinc lies above iron in the reactivity series and is more reactive than iron. thus, in the presence of zinc, iron does not corrode. q4. what do metals form upon reaction with water? give a general ...
(OER)6—one of the electrochemical half reactions for water splitting—where the current catalysts of choice are made from oxides of expensive noble metals, unfeasible for large-scale application. However, recent progress has shown that inexpensive oxides based on 3dtransition metals are promising ...
It was proposed that a higher efficiency could be achieved by substituting an N–M′ group (M′ = alkali metals) for the N–H moiety using a large excess of metal alkoxides (M′OR); however, such a metal-hydride amidate intermediate has not yet been isolated. Here we present the...
