Give the exact number of each atom present in the smallest unit of a substance

molecular formulas

Used to show the arrangement of the atoms in the molecule or ion, which atoms are banded to one another, and how many bonds hold them togwther.

structural formula

Are formulas that show which elements are present and in what ratio they exist in the substance

empirical formulas

Element w/ a charge

ions

Naming inorganic compounds rules

cations keep their name, anions replave last 3 letters w suffix ide, when molecular ion is present the molecule keeps its name

Are symbolic repressntations of chemical processes that use standardized notation to communicate information in an efficient manner

chemical equations

identified as word equation

reactants and products

Where each substance is then represented by its correct chemical formula along w their respective states

skeleton equation

Melting of ice, do not involve any change in the chemical comp of a substance

physical changes

A substance reacts w oxygen and releases energy in the form or heat n light. / direct breakdown of the reactants

combustion reaction

Chemical change in which two or more substances react to form a single new substance. /Combination of two or more elements/molecules

combination/synthesis

One element replaces another element in a compoound. Also knows as displacement. / Changing one ion in a larger molecule

single rep

Changing either cation or anion of 2 large molecules. / chemical change where there is an exhange of positive ions between two compounds.

doule rep

Splitting of single molecule to diff parts./ one single compound breakdown into two or more simplre substance

decomp

A change in the chemical composition of the original subtance

chemical change

Named by naming the cation firsr and the anion next.

ionic compounds

Co2 + h20

combustion

A+b =ab

synthesis

Ab =a+ b

decom

A+ bc= b+ac

single rep

double rep

Naming of chemical compounds

nomenclature

organic molecules that is made of the following elemtns: hydrgogen n carbon

saturated hydrocarbons

any class of organic chemical compound composed only of C and H

hydrocarbon
