COMPOUND NOMENCLATURE AND EQUATION OF REACTION CLASS X SEMESTER 1 SMKN 7 BANDUNG Chemical Formula Formula expressing type and number of atoms with typical composition for every molecule Element Chemistry formula Consisted of one atoms (monatomic) equal to the element atom symbol Hal.: 2 Isi dengan Judul Halaman Terkait Adaptif Elements Tables Monoatomik Hal.: 3 Isi dengan Judul Halaman Terkait Adaptif Molecule Formula It is formula expressing type and number of atoms forming the compound molecule Element molecule Formula be formula expressing the same atoms alliance forming molecule Hal.: 4 Isi dengan Judul Halaman Terkait Adaptif Molecule Diatomic that is molecule formed from two the same atoms Hal.: 5 Isi dengan Judul Halaman Terkait Adaptif Molecule Poliatomik that is three the same atoms or more joining forms a molecule Hal.: 6 Isi dengan Judul Halaman Terkait Adaptif Compound Molecule Formula express structured compound formula to two atoms or more different forming molecule Hal.: 7 Isi dengan Judul Halaman Terkait Adaptif Empiric Formula empiric formula express simplest comparison from amounts compiler atom a molecule. Hal.: 8 Isi dengan Judul Halaman Terkait Adaptif Oxidation Number Oxidation number or level of oxidation is atom charge value in forming a molecule or ion. The charge earns positive valuable or negativity. Inveterate oxidation number is shortened [by] number oxidation. Some atoms only had one oxidation numbers, there is also atom having oxidation number multiple. Hal.: 9 Isi dengan Judul Halaman Terkait Adaptif Compound Nomenclature and Equation of Reaction Chemical Formula Element Chemistry Formula Molecule Formula Element Molecule Formula Molekul Diatomik Hal.: 10 Compound Nomenclature Oxidation Number Empiric Formula Compound Molecule Formula Rule / determination order of Oxidation number Polyatom Compound Binary Compound From non metal elements Molecule Poliatomic From metal element and nonmetallic element Name of cation called as in advance is followed name of anion Sour nomenclature Isi dengan Judul Halaman Terkait Alkaline nomenclature Adaptif Equation of reaction pA + gB rC + sD A & B as reactant C & D as result of reaction p, q, r, s as reaction coefficient Hal.: 11 Isi dengan Judul Halaman Terkait Adaptif What putting on a par reaction ? Conservation laws of mass; Number of masses before reaction equal to number of masses after reaction. Number of reactant atoms equal to number of atoms result of reaction Dalton Law; a compound formed from atoms alliance Hal.: 12 Isi dengan Judul Halaman Terkait Adaptif Example of equivalent Reaction Of Direct mode ( simple); Puts on a par equation of reaction : Solution a. number of atoms Al is left = 1, while in right = 2, so that coefficient Al on the left is multiplied 2, becomes b. Number of atoms O in left = 2, while in right = 3 so that coefficient O on the left is multiplied, becomes c. In order not to be in the form of fraction, equation reaction of multiplied 2 so that reaction of wholly becomes Hal.: 13 Isi dengan Judul Halaman Terkait Adaptif Applies way of equation; Solution Taken example each coefficient is marked with letter a, b, c, d, and e; Every atom is equalized the numbers between left internodes and joint right Left internodes = joint right Number of atoms Cl 2a = c + d equation 1 K b = c + d equation 2 O b = 2d + e equation 3 H b = 2e equation 4 Taken example a = 1 so that a = 1, b = 2, c= 1 , d= , and e= 1 Hal.: 14 Isi dengan Judul Halaman Terkait Adaptif In order not to be in the form of fraction, the coefficients is multiplied [by] 2 becomes a= 2, b= 4, c= 3, d=1, and e=2. So, equation reaction of wholly Hal.: 15 Isi dengan Judul Halaman Terkait Adaptif Thank You Hal.: 16 Isi dengan Judul Halaman Terkait Adaptif
