Het mixture- mixture of sand and sugar is a heterogeneous mixture. The grains can be distinguished from each other with a magnifying glass. There are two solid phases: the sand grains, and the sugar grains. The mixture can be separated by washing the sugar out with water (a physical change malleable-apable of being extended orshaped by hammering or bypressure from rollers. Solid-having three dimensions (length,breadth, and thickness), as ageometrical body or figure. Solid-having three dimensions (length,breadth, and thickness), as ageometrical body or figure. Calcium-:a silver-white divalent metallic element of the alkaline-earth group occurring only in combination — see element table. sulfur - nonmetallic elementthat exists in several forms, theordinary one being a yellowrhombic crystalline solid, andthat burns with a blue flame anda suffocating odor: usedespecially in making gunpowderand matches, in medicine, invulcanizing rubber, etc. Symbol:S; atomic weight: 32.0. Halogen-
any of the electronegativeelements, fluorine, chlorine,iodine, bromine, and astatine,that form binary salts by directunion with metals. Ductile- apable of being hammered outthin, as certain metals;malleable. Liquid- composed of molecules thatmove freely among themselvesbut do not tend to separate likethose of gases; neither gaseousnor solid. Chem change- Chemical change is anychange that results in the formation of new chemicalsubstances. At the molecular level, chemical changeinvolves making or breaking of bonds between atoms. Homo mix- mixture which has uniform composition and properties throughout. For example, air is ahomogeneous mixture of gases. A teaspoonful of table salt stirred into a glass of water also makes a homogeneous mixture. Alltropic- are different structural modifications of an element; the atoms of the element are bonded together in a different manner. Potassium- Potassium is a mineral found in foods. It is also an electrolyte, which conducts electrical impulses throughout the body. Potassium assists in a range of essential body functions, including. Allkine metal-
Any of a group of metallic elements that includes beryllium, magnesium, calcium, strontium, barium, and radium. Because the alkaline-earth metals have two electrons in their outer shell, they react easily with other elements and are found in nature only in compounds. See Periodic Table. Tran metal- any type of metallic elements occupying a center block. Phy change-
Definition of Physical Changes. Substances often undergo changes that make them have a dramatically different appearance even though the chemical composition of the substance remains unchanged. For example, you can take a flat, smooth sheet of paper and crumple it into a ball or fold it into an airplane.
