Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Double Displacement Method In the last two articles, we have studied the hydrogen displacement method, oxide formation method, reduction method, and chloride formation method to determine the equivalent mass of metal. In this article, we shall study double displacement method and metal displacement […]
Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Oxide Formation, Reduction, and Chloride Formation Method In the last article, we have studied the hydrogen displacement method to find the equivalent mass of an element. In this article, we shall study three more methods oxide formation method, reduction method, and chloride formation […]
Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Hydrogen Displacement Method In the last few articles, we have studied the concept of atomic mass and methods to determine it. In this article, we shall study the hydrogen displacement method to determine the equivalent mass of a metal. The equivalent mass of […]
Science > Chemistry > States of Matter > Charle’s Law Mathematical relationships between volume, pressure, and temperature of a given mass of gas are referred to as Gas laws. In this article. we shall study Charle’s Law. Charle’s Law: The relationship between the volume of a gas and temperature was observed by Jacques Charles in […]
Science > Chemistry > States of Matter > Boyle’s Law Mathematical relationships between volume, pressure, and temperature of a given mass of gas are referred to as Gas laws. In this article. we shall study Boyle’s Law. Boyle’s Law: In 1662, Robert Boyle, on the basis of his experiments put forward the law. It is […]
Science > Chemistry > States of Matter > Gaseous State In this article, we shall study the general characteristics of the gaseous state and the measurable properties of gases. General Characteristics of Gaseous State: A gas has neither a definite shape nor a definite volume. They acquire the volume and shape of the container in […]
Science > Chemistry > States of Matter > Hydrogen Bonding Consider two polar molecules water H2O (molecular mass 18 and dipole moment 1.8 D) and nitrosyl fluoride ONF (molecular mass 49 and dipole moment 1.8 D). As their dipole moments are the same, their boiling points should be comparable. But boiling point of water is 100° […]
Science > Chemistry > States of Matter > Interaction Between Molecules Intermolecular forces are the forces of attraction between neighbouring molecules, situated at a distance much closer in comparison with their molecular diameter. They vary from state to state of matter. These forces exist in all states of matter. Liquid and solid states of matter […]
Science > Chemistry > States of Matter > Change of State of a Substance In this article, we shall study a change in the state of a substance. Melting (Solid → Liquid): The process of change of solid substance into its liquid state is called melting or fusion. The constant temperature at which the solid […]
Science > Chemistry > States of Matter > Introducion A matter is defined as anything that has mass, which occupies space and may be perceived by senses. There are three states of matter, viz. (a) solid, (b) liquid, and (c) gaseous states. Historical Perspective of States of Matter: Ancient Indian philosophers suggested that all the […]
