Introduction There are several instances when ratios and percentages are employed. The proportion and ratio ideas you acquired in earlier sessions are still fresh in your mind. On a milk packet, several milk components are listed in percentages. A certain ratio of finger millet flour and wheat flour is used to make ragi bread. To […]
Introduction Forests are essential to human life due to the diverse materials they provide. They produce oxygen, which is required for life on Earth, act as a carbon sink, and store carbon, earning them the moniker “earth lung.” Furthermore, they regulate the hydrological cycle and the global climate; purify water; provide habitat for wildlife, reduce […]
Introduction Old chemical bonds are cleaved in a chemical reaction and form new bonds. Any chemical equation should be balanced properly. It means the number of each atom should be the same on both the reactant and product sides. It is based on two rules; the ‘law of conservation of masses’ and the ‘law of […]
Introduction In European history, the French Revolution was a revolutionary movement that brought about profound societal and political changes. The role that women played in the revolution was amazing. Women’s participation was only allowed in the domestic sphere before the Revolution or during its early years. They all desired, though, to air their concerns and […]
Introduction Circuit boards, plastic light fixtures, switches, and sockets can all be made of the synthetic material known as Bakelite. The characteristics include non-absorbency and non-conductivity, as well as high-temperature resistance. Because it is utilized in electronic devices, it is referred to as “Bakelite.” A heated mixture of granular phenolic resin, sawdust, and asbestos is […]
Introduction The scientist, Antonio Lavoisier, introduced the law of conservation of mass in the year 1789. According to him, mass can’t be destroyed or generated. But mass can be transformed from one form to another. In our daily life, we also utilize this law. For example, in the burning process of wood, the total masses […]
Introduction Chemical reactions operate on the type of reaction and change principle, which states that when a reactive substance interacts with other chemicals, different reactions will occur. Chemical reactions occur in stable or least reactive compounds as well, albeit under more extreme conditions. When reactants combine to produce a product, heat is released or absorbed, […]
Introduction Aufbau is a German word that means “building up.” Like a construction build-up from the ground up. Atoms are also filled with electrons in this manner. An atom has orbitals that are arranged in increasing energy level order. According to the Aufbau principle, electrons are filled in the order of increasing energy of the […]
Introduction We come across several items of various shapes and sizes in our daily lives. Many items have three sides, whereas others have four, five, and so on. Some forms have equal sides on all sides, whereas others do not. Consider our laptop screen, deck of cards, tabletop, chessboard, carrom board, and kite as examples. […]
