Sugar and salt crystals are made of entirely different elements and have very different chemical and physical properties. While both dissolve readily in water, they dissolve in different ways, and unlike sugar, the dissolution of salt is largely unaffected by temperature. Their greatest similarities are in their common appearance as small white crystals and their use in the preparation and flavoring of food.Know More
The sugar most often used by humans is sucrose. This covalent compound is most often derived from sugar beets or sugar cane. It is composed entirely of covalently bonded carbon, oxygen and hydrogen atoms. The bond between oxygen and either carbon or hydrogen is very polar, and the configuration of the sucrose molecule makes it polar overall. It is this polar nature that allows sugar to dissolve readily in water, with its solubility increasing at higher temperatures.
The salt most commonly encountered by humans is sodium chloride. Sodium chloride crystals are not made of individual molecules; they are composed of a crystalline lattice of sodium and chloride ions. Each sodium ion is ionically bonded – that is, held together with opposite charges – to each of the chloride ions around it. When salt dissolves, the water is pulling individual ions into solution rather than whole molecules, as is the case with sugar.Learn More
Natural gas is a fossil fuel composed of flammable gases, primarily methane, that formed from decaying organisms buried deep beneath the Earth's surface due to intense heat and pressure over thousands of years. It is one of the major energy sources throughout the United States and the world.Full Answer >
Elevated temperature, immersion in a humid and oxygen rich environment, contact with a metal that is lower in the electrochemical series, and mechanical agitation are conditions that cause an iron nail to rust faster. Rusting is a decomposition reaction where iron reacts with oxygen and water to form hydrated ferrous oxide and hydroxide.Full Answer >
The chemical formula for barium permanganate is Ba(MnO4)2. Ba is the chemical symbol for barium, Mn is the chemical symbol for manganese and O is the chemical symbol for oxygen. The chemical symbol for each element can be found on the periodic table of elements.Full Answer >
Amylose is a glucose polymer with long chain-like molecules, while amylopectin consists of larger highly branched molecules (1 to 6). Glycogen consists of even more branches than amylopectin. Amylose and amylopectin are classified as starch, and are found in plants, while glycogen serves as the main energy reserve for animals.Full Answer >
