It is the chemistry of specific carbon compounds except oxides, carbonates, and carbides. Organic compounds are composed of carbon and hydrogen only. Examples: Methane (CH4), and ethane (C2H6). Compounds with the same molecular formula but different structural formulas are known as isomers, and the phenomenon is known as isomerism. Examples: Butane and isobutane are two […]
An acid is a compound that when dissolved in water yields hydronium ions (H3O+) as the only positively charged ions. A base is either a metallic oxide or a metallic hydroxide or an ammonium hydroxide which reacts with hydronium ions of an acid to form salt and water only. A salt is a compound formed
Molecular formula: HClMolecular mass: 36.5 amuBond: Covalent HCl is Colorless, pungent, choking odor, and has a slightly sour taste. It is 1.28 times heavier than water and highly soluble in water. Liquefies at a temperature of about 10°C at 40 atmospheric pressure. The boiling point is −83°C and the freezing point is −113°C. Hydrogen Chloride
It is a table that classifies all the known elements in accordance with their properties in such a way that elements with similar properties are grouped together in the same vertical column and dissimilar elements are separated. The 115 known elements are arranged in the Periodic Table in order of their increasing atomic number. The
The process used for the extraction of metals in their pure form from their ores is called metallurgy. The naturally occurring compounds of metals which are generally mixed with other matter such as soil, sand, limestone, and rocks are known as minerals. Earthy impurities, including silica and mud, associated with the ore are called gangue.
Molecular formula: H2SO4; Relative molecular mass: 98. H2SO4 is colorless, odorless with a slightly sour taste. It is highly corrosive in nature and chars the skin black. It is heavier than water and soluble in water. Boiling point is 338°C, and the melting point is 10.4°C. Sulphuric Acid PDF Download PDF
Electrolysis is the process of decomposition of a chemical compound in an aqueous solution or in a molten state, accompanied by a chemical change using direct current. An electrolyte is an ionic compound that in the fused state or in the aqueous solution allows the passage of an electric current and is decomposed by it.
Boyle’s Law: The volume of a given mass of a dry gas is inversely proportional to its pressure at a constant temperature.P1VI = P2V2 = k at a constant temperature. Charles’s Law: The volume of a given mass of a dry gas is directly proportional to its absolute temperature if the pressure is kept constant.
The determination of the chemical components in a given sample is called analysis. Types of Analysis: Qualitative Analysis: It involves the identification of unknown substances.Quantitative Analysis: It involves the identification of the composition of a mixture.
