Which type of element forms ions with a -1 charge? a. Alkaline earth metals b. Alkali metals c. Noble gases d. HalogensDetermine the element being described or defined by the following statement: The most reactive noble gas. Choose from the following elements: | lithi...
it has properties that are intermediate between those of chlorine and iodine. Bromine is one of the most abundant and ubiquitous of the recognizedtrace elementsin the biosphere. However, it has not been conclusively shown to perform any essential function in animals, plants or microorganisms (Pavelk...
(IA) of (I) to form a new structure in which (III) are incorporated. Pref. (IA) contains C1 and/or F atoms. The cell may contain ion type(s) with the opposite charge to (III); and/or ion(s) contg. gp. IA and IIA element(s) and/or ion(s) contg. O, S, P. Bi, Ti,...
The chromatographically separated fractions are identified by their retention times and elementspecific detection with a microwave plasma detector. Methyl bromide, 1,2-dibromoethane, and vinyl bromide are analysed in exhaust gases in cases where the gasoline contains 1,2-dibromoethane as an additive...
Chlorine to bromine ratios remain nearly constant at 430 ± 130 (1σ) over a Br concentration range of 60–1300 ppb, similar to the exospheric ratio (390), and independent of the basalt type. Along the MAR, chlorine can be described as a conventional incompatible trace element which ...
The totalities of electron-acceptor and electrodonor substituents R are described by equations of the same type differing in their parameters.doi:10.1007/BF02503482G. K. SeminA. N. Nesmeyanov Institute of Organoelement Compounds, Russian Academy of Sciences, Moscow, Russian FederationS. A. ...
As a consequence, the best management strategies have to be identified for this class of products [2] in order to maximize their materials and precious element recovery [3,4], thus avoiding environmental pollution [5]. With reference to the recovery of secondary plastics coming from WEEE, one...
The invention provides a decorative type styrene-acrylic bromine carbon latex fire-retardant coatings and preparation method thereof. The induction of flameretardant element bromine and synthesis of intrinsic flamertardant polymer resin can increase ageing effect and flame retardant property of fire-...
After 5 repeated reactions, the desulfurization rate of coal samples can reach 90%. In order to explore the change pattern of sulfur element form and content, X-ray photoelectron spectroscopy (XPS) was used to analyze the change of sulfur form in the solid phase (coal). Ion chromatography (...
