Most of the substances we use are mixtures. Milk, a popular animal product that we consume almost daily, is a mixture. The main components found in milk are proteins, water, fats, and minerals. The fat content in regular milk is 3.5%. The fat content in milk can be reduced to 1.5%. After removing the fat …
Most of the substances we use in our daily life are mixtures. Air is a mixture of nitrogen, oxygen, carbon dioxide, inert gases, water vapor, and dust. Crude oil is a mixture of different components such as petrol, kerosene, bitumen, gasoline, diesel, and gaseous alkanes. By definition, a mixture is a substance made up of …
Every football team that plays in competition always has substitute players. That’s an extra number of players who can be quickly called in to replace another player if he gets hurt. The world of chemistry also has substitutes. It happens in types of reactions called single displacement reactions. This is a reaction where an element …
The reactions taking place around us and in the lab can be classified into many types. One of these is a decomposition reaction—a reaction where a compound is split into simpler substances. The reaction has a single reactant as a starting substance. This breaks down into two or more products. The general form of a …
QUICK DEFINITION: The Law of Conservation of Mass states that in a closed system, the total mass remains constant over time; mass cannot be created or destroyed, only rearranged or transformed in reactions. EXPLANATION: Every self-respecting chemist knows one thing about chemical reactions: the total mass of materials before the reaction and the mass of …
DEFINITION: A double replacement reaction is a chemical process where two compounds exchange ions, leading to the formation of two new compounds, typically occurring in aqueous solutions and producing a precipitate or gas. EXPLANATION: In the chemistry world, we classify many things such as elements and compounds. We also classify the reactions that these substances …
DEFINITION: A suspension mixture is a heterogeneous combination where particles of a substance are dispersed but not dissolved in another medium, remaining suspended due to gravity and requiring agitation for stability. EXPLANATION: There’s nothing better than a hot cup of chocolate on a cold day to warm the body up. If you want to make …
DEFINITION: A colloid mixture consists of small particles dispersed in another substance, creating a homogeneous yet not fully dissolved solution. It exhibits intermediate particle size between solutions and suspensions. EXPLANATION: You’re probably familiar with a variety of mixtures such as suspensions and solutions. Colloid mixtures are one of the primary types of mixtures. They are …
