Hydrogen is the first and the smallest element of the periodic table. Hydrogen contains only one electron and one proton in its nucleus. I

Lead is the heaviest member of the carbon family. Lead is a bluish-white lustrous metal. It is extremely soft, extremely malleable, ductile, and a relatively poor conductor of electricity.

According to Kinetic Molecular Theory, gaseous particles remain in a constant state of motion, moving at random speeds and in many different directions. Because of their kinetic energy at a temperature above absolute zero, all particles undergo diffusion.

An electrochemical cell that converts the chemical energy of redox reactions into electrical energy is called a galvanic cell or a voltaic cell. The cell uses spontaneous redox reactions to create an electrical current.

While all drugs can be unsafe, specifically illegal substances or drugs that are utilized without a prescription, some are more dangerous than others.

A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH.

Gypsum Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO4.2 H2O) is similar to Anhydrite (CaSO4). The chemical difference is that gypsum includes two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Calcium oxide is an odor-free crystalline or powdery solid that, in a pure form, is white to off-gray. It typically appears with a yellow-colored or brownish tint to the presence of impurities, specifically iron.

When the molecules of a liquid leave the open surface area, they are mixed up with air above the liquid. If the vessel is open these molecules go on leaving the surface area.

Salt hydroxide is sometimes called caustic soda or lye. It is a common ingredient in cleaners and soaps.
At room temperature level, sodium hydroxide is a white, odor-free solid.
