The law of conservation of mass states that in a closed system, mass cannot be created or destroyed; it can only change forms. This principle is a fundamental concept in chemistry and physics, and it means that during a chemical reaction, the total mass of the reactants will be equal to the total mass of the products.
The type of chemical bond that involves the sharing of electrons is a covalent bond. In a covalent bond, atoms share electrons to achieve a more stable electron configuration and form molecules.
The unit of measurement for the amount of substance in chemistry is the mole (mol). A mole is defined as the amount of substance that contains the same number of entities (atoms, molecules, ions, etc.) as there are atoms in exactly 12 grams of carbon-12.
The chemical name for vitamin C is ascorbic acid. It is an essential nutrient for humans and is known for its antioxidant properties.
The process by which a solid changes directly into a gas without becoming a liquid is called sublimation. Sublimation occurs when the substance's vapor pressure exceeds its atmospheric pressure at a certain temperature, allowing the solid to transform directly into a gaseous state.
The main function of enzymes in biological systems is to catalyze (speed up) chemical reactions. Enzymes are protein molecules that act as biological catalysts, lowering the activation energy required for a reaction to occur. They enable biochemical reactions to proceed at a suitable rate under the conditions present in living organisms, without being consumed or altered in the process. Enzymes play a crucial role in various biological processes, including digestion, metabolism, and cellular signaling.
