In chemistry, a filtrate is a liquid that has passed through the filtration process. In this process, liquid is strained. Bigger particles get stuck in the strainer, while smaller particles and liquid pass through, becoming filtrate.
A:When iodine is heated, the intermolecular bonds are broken and the iodine goes directly to vapor from solid crystalline form. This is because the bonds are too weak to sustain liquid form under those conditions (slightly above room temperature and standard atmospheric pressure). If you were to continue heating the iodine, it would eventually melt at 113.6 degrees Celsius, and it would boil at 185 degrees C.
A:The purest water that is theoretically possible would consist of nothing but H2O molecules and exclude substances like minerals and salts. This maximum is never truly achieved for large samples in practice, so the term "pure water" has taken on different meanings that vary by the water's intended use.
A:Kerosene is a mixture of hydrocarbons and does not have a single chemical formula. The hydrocarbons in the mixture include compounds with 10 to 16 carbon atoms in both straight chain and branched formations.
A:Ionic compounds dissolve in water because the hydrogen and oxygen atoms in the H2O molecules have partial charges that attract the ions in the solid compound, causing it to dissociate into separated ions. Differences in electronegativity account for the partial positive charge carried by water's hydrogen atoms and the partial negative charge of its oxygen atoms. What is happening to the ionic compound when it dissolves is a separation of its ions from their preexisting solid crystal lattice structure into unattached ions that are free to move about in the solution.
A:In chemistry, a filtrate is a liquid that has passed through the filtration process. In this process, liquid is strained. Bigger particles get stuck in the strainer, while smaller particles and liquid pass through, becoming filtrate.
A:According to Mental Floss, the luminescence inside glow sticks comes from a chemical reaction between two substances that releases energy as light. The exact chemical makeup of a glow stick can vary from manufacturer to manufacturer, but most use hydrogen peroxide and a chemical called a diphenyl oxalate ester. When the two liquids mix inside the glow stick, they produce a light colored by a phosphorescent dye.
A:Most of the helium gas used to fill balloons is a mixture because commercial helium is seldom pure. Usually, it contains impurities in the form of nitrogen and oxygen gas. However, the helium present in this mixture is also a substance.
A:Another name for a homogeneous mixture is a solution. The term "solution" is more frequently used when a homogeneous mixture is a liquid, although it is sometimes used if the homogeneous mixture is a gas. Another name for a solid homogeneous mixture of metals is an alloy.
A:Some examples of highly viscous liquids are oils, honey, glycerin, tar and sulfuric acid. Viscosity is the ability of substances, especially fluids, to resist flow. It can also be referred to as the measure of the ability of a liquid to resist being deformed by extensional stress.
A:Filtration is a method of separating solid impurities from liquid by allowing the liquid to pass through a filter, which usually consists in a porous material such as cotton wool, cloth, paper, glass wool or asbestos. The filter traps solid particles, and the size of its pores or holes determines which particles pass through. Water flows through the material at a low speed.
A:Peeling paint can be due to any of three common causes, including lack of surface preparation, moist walls and wrong paint, according to Red Beacon. If the wall underneath is dirty, wet or covered in old paint, the paint on top of the bad layer may not hold properly. One way to fix peeling paint is to paint the wall correctly after scraping off the malfunctioning layers.
A:A dehydrating agent is a substance that dries or removes water from a material. In chemical reactions where dehydration occurs, the reacting molecule loses a molecule of water. Sulfuric acid, concentrated phosphoric acid, hot aluminum oxide, and hot ceramic are common dehydrating agents in these types of chemical reactions.
A:In scientific language, a solution is a mixture of at least two substances in which the particles of the substances are of atomic or molecular size. A solution is a homogeneous mixture, which means that all parts of the mixture are exactly the same as every other part.
A:To separate alcohol from water, you must heat the solution, evaporate the ethanol into vapor, cool it down and condense it back into a liquid using a distillation apparatus. This process is called distillation, and it is used to separate a pure liquid from a liquid mixture. Distillation works for liquids that have different boiling points.
A:Heterogeneous and homogeneous mixtures are identified by the level at which the mixtures blend together. Visible indications of different components within a mixture denote a heterogeneous mixture, while a uniform, single-component appearance indicates a homogeneous mixture.
