Ionicbonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. How do you identify ionic compounds? To find the formula of an ionic ...
For starters, there's a nice pic here:http://en.wikipedia.org/wiki/Iron%28II%29_sulfideoooh and apparently powdered iron(ii) sulphide ispyrophoric- it bursts into flames readily with the air lol Umm..in the last question you asked me, you gave me a formula to work with...do you ha...

The compounds of Formula III can hydrolyze under various conditions to secondary amines. The hydrolysis produces products having the Formula IV: ##STR3## The compounds of Formula III are disclosed in U.S. Pat. Nos. 3,037,006 and 3,502,627 in the hands of a common assignee, and their ...
When this Y doped SZO, with a general formula of SrZr1-xYxO3-δ, meets water or steam, proton defects\({{OH}}_{O}^{\bullet }\)will be formed. $${V}_{O}^{\bullet \bullet }+{O}_{O}^{\times }+{H}_{2}O\to 2{{OH}}_{O}^{\bullet }$$ ...
Binary Ionic Compounds (Type I) 1. The cation (positively charged ion; Na +, Al 3+ ) is always named first and the anion (negatively charged ion; Cl - , O 2- ) second. 2. A monatomic (meaning one-atom) cation takes its name from the name of the element. For example, Na + ...

Each of these ionic copolymers can also be employed with counter ions other than chloride, for example, a conjugate base of a pharmaceutically acceptable acid. In a further embodiment, the polymer to be administered comprises a monomer of Formula I, a hydrophobic monomer and a neutral ...
(0.21 g, 0.2 mmol) were heated at 95°-100° C. with stirring for 24 hours. On cooling the catalyst was filtered off through Celite and washed with dichloromethane. The filtrate was washed with dilute hydrochloric acid (×3), brine, dried over magnesium sulphate and evaporated. Dodecyldi...
