Chemistry is one of the branches of natural science that deals with matter and their interactions.This is commonly known as ‘central science’ as there is connections found between physical, biological and geological disciplines. Though, chemistry is derived from physical sciences, it has its own uniqueness. The word chemistry is derived from the word alchemy and the origin is traced way back from ancient civilization. Robert Boyle defined the term ‘Chymistry’ meaning ‘mixture’ and later on ‘chemistry’ evolved. Chemistry is divided into 6 different subdivisions, which is covered in Chemistry assignment help. They are: General Chemistry, Physical Chemistry, Organic Chemistry, Inorganic Chemistry, Analytical Chemistry, and Biochemistry
General chemistry assignment help:General chemistry is an outline of the matter and physico-chemical interactions.
Physical chemistry assignment help: Physical chemistry applies the principles and concepts of physics in the chemical system. Quantum chemistry and thermodynamics forms the principle of this science.
Organic chemistry assignment help:Organic chemistry deals with the structure and function of organic compounds and materials. This involves the learning of hydrocarbons (compounds with carbon and hydrogen) and compounds based on association with carbon.
Inorganic chemistry assignment help:This includes the synthesis and functioning of organic, inorganic and organo metallic compounds (except carbon based compounds). Major classes are oxides, carbonates, sulphates and halides.
Analytical chemistry assignment help: Analytical chemistry deals with separation, identification and quantification of the chemical components and determines the amount of the substance. Electrophoresis and Chromatography are the techniques involved in separation of molecules.
Biochemistry assignment help:Biochemistry is the study of biochemical reactions in the biological system. The bio molecules include proteins, carbohydrates, lipids and nucleic acids, which are important to maintain healthy growth of the organism.
Chemistry details the chemical interactions and explains the principle of chemistry. Matter and energy are the two major components. ‘Matter’ is made up of small particles and atom is the basic unit of chemistry. Atom has nucleus that is surrounded by negatively charged electron, positively charged proton and a neutral neutron. Atoms combine to form molecules by chemical bonds. John Dalton postulated ‘atomic theory’ and Loschmidt determined the size of the molecules.Matter is classified based on its physical state as solid, liquid and gas and chemical constitution as an element, compound and mixture.
Physical state and chemical composition of matter: Water is the best example to explain the physical state of matter viz., solid water – ice, liquid water – drinking form and gaseous water – steam. The chemical composition deals with the change in the nature of physical state of matter i.e., dissolution of sugar or salt into water. The physical state of the sugar is crystal, which breaks down by the action of hydrogen and oxygen molecules in the water to form a clear solution. A chemical substance is a type of matter that cannot be separated by any physical means and an element as a substance cannot be decomposed to simple matter by any form of chemical reactions; a chemical compound is the substance made of 2 or more elements; and a mixture refers to a material that can be separated into 2 or more substances by physical means. The Systemic Classification is the measurement system of matter and is represented as SI (Systeme international) Unit for length, mass and volume. The periodic classification of elements forms the log for the chemical studies and the elements are classified to determine metals, non-metals or metalloids and families and periods.

Chemicals also find a role in industries and commercialization of chemicals has increased the world economy. Chemistry homework help details the chemical applications and their role in industries to produce products like polyethylene, polyvinyl chloride pipes, nylon and polyesters. Liquid Petroleum Gas (LPG) and crude oil are also the by products of petrochemical industries. Phosphate and ammonia fertilizers bring some revenue by helping farmers. Day to-day activities, from soaps to drugs, edge a lifestyle with these commercial commodities. Pharmaceutical industries have gained attention with improvement in recent technologies enriching formulation and production of new/novel drugs. Biochemistry, biotechnology and analytical chemistry are few of the natural science branches that promises tread towards modern and contemporary universe.

Chemistry homework help from Ask Assignment Help let students understand the basic essence of chemistry. This is a central science as it has connections with physics, biology and earth science. Since it deals about chemical interactions and reactions, Chemistry has got its name. The discovery of chemistry was from ‘Alchemy’, an ancient practice, which evolved to produce a materialistic science – Chemistry.
The properties of the substances and interactions between different matters; atomic and nuclear realm facilitates the improved enrichment in learning and understanding chemistry. Chemistry online tutors enlighten the subject, chemical science, by providing details about its co relation with physical laws that control atoms, electrons thermodynamics and quantum mechanics and also the concept of periodical classification and chemical bonds are well explained. Even in biological sciences, the genetic bases, proteins, carbohydrates and lipids provide the chemical existence and importance for life. Albert Einstein’s equation E = mc2, describes that the atomic mass can be converted into energy in a nuclear reaction. Any type of chemical reactions involves reactant, products and catalysts. Combination, decomposition, displacement, double displacement reactions, Oxidation and reduction and exothermic and endothermic reactions are the main kinds of chemical reactions. The factors that influence the chemical reaction rate are nature, concentration, and surface area of reactants, temperature and catalyst. Metallurgy is an important property in chemistry, as it constitutes the mineral affluence of the country.
Energy: Energy is the ability to do work and two main types of which are potential (stored form of energy) and kinetic energy (motion). The study of heat, temperature and energy is termed as thermo chemistry.
Temperature, pressure and volume: At constant temperature, volume is inversely proportional to pressure (Boyle’s Law). At constant pressure, the volume is directly proportional to temperature (Charles’s Law).
Water – a universal solvent: Water is a universal solvent and can participate in any chemical reactions. The physical states of matter are solid, liquid and gas and many processes are involved for the transformation of one form to another, energy as a catalyst. The characteristics of water are solubility, Cohesion and adhesion, and chemical reactivity enables to best understand the nature of water – made of hydrogen and oxygen (H2O). Solutions, colloids and suspensions are the type of matter based on viscosity and mass.
Acids, bases and Salts: Acids, bases and salts play a vital role in daily life. Acids are proton donors and classified based on their sources (organic and inorganic acids), basicity (mono, di and tri – basic acids), ionization (strong and weak acids) and concentration (dilute and concentrated acid). Bases are proton acceptor and are classified based on their acidity (mono, di and tri – acidic bases), ionization (strong and weak bases) and concentration (dilute and concentrated alkali). pH refers to the power of Hydrogen ions and it is used to determine the acidity and alkalinity of a solution. The pH of a normal healthy man is 4.5 to 6 and microbial infections and infestations changes the pH inside the body e.g. for cold and fever, the pH is 6.9 and drugs act to bring it down to normal range. Salts are the products of the reaction of acids and bases. Normal, acidic, basic and double salts are the basic types of salt and they are used as common salts, washing soda, and bleaching powder.
To sum up, chemistry online tutors provide a clear outline of chemistry as a domain that embodies every part of life. The combination of different atoms and molecules follows basic laws that propose various concepts through the Laws of Conservation of mass, Avogadro’s Laws and Dalton’s atomic theory. A balanced chemical reaction provides several data and stoichiometry refers to the quantitative study of the required reactants to produce products
