Lithium is an alkali metal widely used in industry. Dilithium oxide is technically correct for LiO2, but little used outside the academic arena. BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment. We have our own unique team. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. It can also be made through the thermal decomposition of lithium hydroxide, LiOH, or lithium peroxide, Li2O2. If at least one company has indicated that the substance classification is affected by impurities or additives, this will be indicated by an informative sentence. Both. The data on these compounds pages are assembled and adapted from the primary literature and several other sources including the following. Francium oxide is an ionic compound with the formula Fr[math]_2[/math]O. Its crystal structure is presented in Figure 3 (Mark Winter [The University of Sheffield and WebElements Ltd, 2016]). ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). PubChem Substance ID 24863332. The chemical formula for an ionic compound of potassium and oxygen is . A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. IDENTIFICATION. Linear Formula Li 2 O . Cotton, G.

This is unique source of information on the chemicals manufactured and imported in Europe. The EC or list number is the primary substance identifier used by ECHA. Danger! EC Number 235-019-5. Hazard statements were adapted to improve readability and may not correspond textually to the hazard statements codes description in the European Union Specific Hazard Statements (EUH) or the. The NIST XPS Database gives access to energies of many photoelectron and Auger-electron spectral lines. Lithium hydroxide is an inorganic compound with the formula LiOH. The Waste Framework Directive aims to protect the environment and human health from the generation and management of waste and to improve efficient use of resources. EC Number 235-019-5. Its molecular weight … The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter. This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). According to the classification provided by companies to ECHA in CLP notifications this substance causes severe skin burns and eye damage, causes serious eye damage and is harmful to aquatic life with long lasting effects. Figure 2: appearance of lithium oxide Lithium oxide are crystals with antiflorite geometry similar to that of sodium chloride (cubic centered on the faces). Dilithium is one of the candidate alg… In addition, some lithium peroxide, Li2O2, also white, is produced. EC Number: 235-019-5: Solubility: Soluble in water. Dilithium oxide (Li 2 O) is white cubic crystal with ionic bonds between the lithium and the oxygen. 100204-764 100210-602. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. This information has not been reviewed or verified by ECHA, and may change without prior notice. 03-0343.25 03-0343.100. If the substance is covered by more than one CLH entry (e.g. Actually the formula for lithium oxide is Li2O.It is a is an inorganic chemical compound. It belongs to the product categories of Inorganics; Lithium; Metal and Ceramic Science; Oxides. Linear Formula Li2O. If generated, an InChI string will also be generated and made available for searching. KO. More information about CAS and the CAS registry can be found here. This site is not fully supported in Internet Explorer 7 (and earlier versions). The use of lithium in psychiatry goes back to the mid-19th century. Dilithium oxide. If a substance is classified under multiple CLH entries, a link to the C&L Inventory is provided to allow users to view CLH information associated with the substance and no text is automatically generated for the InfoCard. Linear Formula Li 2 O . The chart below shows the calculated isotope pattern for the formula Li2O with the most intense ion set to 100%. Xia et al. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. answer choices . More information about the EC Inventory can be found here. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. The EC inventory published below is a copy as received from the JRC in 2008 on the founding of ECHA. the electronic edition of the Official Journal of the European Union. N 2 O is a molecular compound (nonmetal bonded to nonmetal). This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. Description. Real-life dilithium (Li 2) materials. MDL number MFCD00016183. WebElements: THE periodic table on the WWW [www.webelements.com] These notifications can be provided by manufacturers, importers and downstream users. The ‘Hazard classification’ and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information.
