Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

survey; it shows that recycling 1 ton of plastic saves the equivalent of 5‚774 kilowatt-hours of electric energy. In addition‚ many companies that using plastic to generate power have established in recent years. Another way to address this problem is Hydride decomposition. This method could transform sixty to eighty percent of the composition of plastic to crude oil. Crude oil is one of the most essential fuels in the world‚ about eighty-eight percent of the crude oil is used to be fuel‚ and so recycling

generating the product. The most common reaction that would mimic the reduction taking place in this experiment is hydride addition using sodium borohydride‚ NaBH4. Normally an alternative to this oxidizing agent would be lithium aluminum hydride‚ LiAlH4‚ however this reagent would also react with the ester portion of our starting reagent. The effect of reducing the ketone via hydride addition is that product is entirely a racemic mixture (McMurry 696). After the initial reaction the product was isolated

Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air to sustain the chemical reaction‚ they can however produce electricity continually for as long as these inputs are supplied.

to learn how to use sodium borohydride to reduce benzil to its secondary alcohol product via reduction reaction. This two-step reaction reduces aldehydes by hydrides to primary alcohols‚ and ketones to secondary alcohols. In order for the reaction to occur and to better control the stereochemistry and yield of the product‚ the metal hydride nucleophile of the reducing agents such as LiH‚ LiAlH4‚ or NaBH4 must be carefully chosen. Being that LiAlH4 and NaBH4 will not react with isolated carbon-carbon
