What do you call a substance containing only one type of atom? What causes a chemical bond to form between atoms? What are some physical properties of minerals? What are the characteristics of chemical elements? What is the chemical formula for the base cesium hydroxide?
Compounds are pure substances, too. Sodium chloride (NaCl), water (H2O), methane (CH4), and ethanol (C2H5OH) have chemical formulas that specify a relationship between the number and type of atoms they contain. Be careful, though, because elements and compounds containing impurities might not ...

(2011/696/EU): 'Nanomaterial' means a natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50% or more of the particles in the number size distribution, one or more external dimensions is in the size ...
A support carrying an immobilized selective binding substance, that the support surface has a polymer containing the structural unit represented by the following General Formula (1) in an amount of 10% or more with respect all monomer units, and a selective binding substance is immobilized on the...
The samples were stored at 40 °C and were analysed every day for one week. The oxidation of ONC201 was studied by preparing an aqueous solution containing 3% H2O2 and 2.5 mg·mL−1 of ONC201 dihydrochloride. This solution was stored at room temperature and the samples were analysed after...
