same with previous years, SPMB soal for chemistry consists of 15 number, which 9 number is ABCD choice, 1 number for Sebab-akibat soal, and 5 number for number choice test, at this year, at this post you will learn about kalor in chemistry, isotope, Isotopes are any of the several different forms of an element each having different atomic mass (mass number). Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons, continued with sulfur trioxide’s reaction ,nitrogen as fertilizer, aminobenzoic (asam benzoat) propana, dielectrics reaction and the last about PH

In organic chemistry, an acyl chloride (or acid chloride) is an organic compound which is a reactive derivative of a carboxylic acid. As part of its molecular structure, an acyl chloride has the reactive functional group -CO-Cl. An acyl chloride has the general formula RCOCl where R is an organic radical group. (wikipedia.com)

about 50 number of chemistry test , the major problems is about : asam-basa reaction (acid reaction),chemistry electrolyte reaction, ion valencies, redoks reaction, oxidation’s and reduction reaction, coligative, ion, catalyzes, corrosion chemistry process.

Catalyst

catalysis is the acceleration (increase in rate) of a chemical reaction by means of a substance called a catalyst, which is itself not consumed by the overall reaction

UMPTN test begin at years 1981, at that time UMPTN consists of 50 number just the chemistry test, begin with electron positions, electron transmission, alkali metal, then colloid.

What is Colloid ? A colloid consists of two separate phases: a dispersed phase and a continuous phase. In a colloid, the dispersed phase is made of tiny particles or droplets that are distributed evenly throughout the continuous phase. The size of the dispersed-phase particles are between 1 nm and 100 nm in at least one dimension (Wikipedia.com)

Interaction between colloid particles
they are various interaction between the colloids particles :

• Excluded Volume Repulsion:
• Electrostatic interaction
• van der Waals forces
• Entropic forces
• Steric forces

back to UMPTN Chemistry test, isotope, boron chloride cell , equilibrium of chemistry reaction, hydrogen and oxygens interaction also some type of test that you must finished.

A chemical reaction is a process that results in the interconversion of chemical substances.The substance or substances initially involved in a chemical reaction are called reactants.Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions.

Reaksi kimia adalah transformasi/perubahan dalam struktur molekul. Reaksi ini bisa menghasilkan penggabungan molekul membentuk molekul yang lebih besar, pembelahan molekul menjadi dua atau lebih molekul yang lebih kecil, atau penataulangan atom-atom dalam molekul. Reaksi kimia selalu melibatkan terbentuk atau terputusnya ikatan kimia

On the classical definition, therefore, there are only two types of chemical reaction: redox reactions and acid-base reactions. The former involve the motion of lone electrons and the latter of an electron pair.

Chemical reactions may be classified in different ways depending on the particular aspect considered for elaborating the division, or on the branch of Chemistry which the classification originates from. Some examples of widely used terms for describing common kinds of reactions are:

Isomerisation, in which a chemical compound undergoes a structural rearrangement without any change in its net atomic composition; see stereoisomerism

Direct combination or synthesis, in which two or more chemical elements or compounds unite to form a more complex product:

Chemical decomposition or analysis, in which a compound is decomposed into smaller compounds or elements:

Single displacement or substitution, characterized by an element being displaced out of a compound by a more reactive element:

Double displacement or coupling substitution, in which two compounds in aqueous solution (usually ionic) exchange elements or ions to form different compounds:

Combustion, in which any combustible substance combines with an oxidizing element, usually oxygen, to generate heat and form oxidized products. The term combustion is used usually only large-scale oxidation of whole molecules, i.e. a controlled oxidation of a single functional group is not combustion.

WHAT IS AN ACID OR A BASE?

By the 1884 definition of Svante Arrhenius (Sweden), an acid is a material that can release a proton or hydrogen ion (H+). Hydrogen chloride in water solution ionizes and becomes hydrogen ions and chloride ions. If that is the case, a base, or alkali, is a material that can donate a hydroxide ion (OH-).

menurut definisi dari Svante Arrhenius seorang ilmuwan swedia, asam (acid) adalah material yang dapat melepaskan ion hidrogen (H+). sedangkan basa adalah material yang dapat melepaskan ion hidroksida (OH-), soal latihan asam basa dapat di download pada akhir posting

Sodium hydroxide in water solution becomes sodium ions and hydroxide ions. By the definition of both Thomas Lowry (England) or J.N. Brensted (Denmark) working independently in 1923, an acid is a material that donates a proton and a base is a material that can accept a proton. Was Arrhenius erroneous?. The Arrhenius definition serves well for a limited use. We are going to use the Arrhenius definitions most of the time. The Lowry- Br?nsted definition is broader, including some ideas that might not initially seem to be acid and base types of interaction. Every ion dissociation that involves a hydrogen or hydroxide ion could be considered an acid- base reaction. Just as with the Arrhenius definition, all the familiar materials we call acids are also acids in the Lowry- Br?nsted model. The G.N. Lewis (1923) idea of acids and bases is broader than the Lowry- Br?nsted model. The Lewis definitions are: Acids are elecron pair acceptors and bases are electron pair donors.
