A reaction that releases heat into its surroundings (e.g., burning of natural gas). 4. Acids, Bases, and Salts

Ores are naturally occurring rocks from which metals can be profitably extracted. Important Ores Hematite, Magnetite, Siderite, Iron Pyrites Aluminum (Al) Bauxite, Cryolite, Corundum Copper (Cu) Copper Pyrites, Cuprite, Malachite Zinc (Zn) Zinc Blende, Calamine Mercury (Hg) Cinnabar (Very frequently asked) Lead (Pb) Sodium (Na) Important Alloys and Their Composition

Knowing the topics is only half the battle. Here's how to make your study time efficient and effective:

Physical combinations of two or more substances without a fixed ratio. chemistry notes ssc
