Water is a polar molecule meaning the oxygen part is negative the hydrogen is positive, so in an ionic compound the negative ion get attracted to the hydrogen and the positive ion to the oxygen.

Mineral luster refers to the way a mineral reflects light from its surface, indicating its appearance and visual quality. It can be categorized into various types, such as metallic, vitreous (glass-like), pearly, silky, and dull, among others. Luster is an important characteristic used in mineral identification, as it helps distinguish between different minerals and their properties.
Geologists primarily classify minerals based on their chemical composition and crystal structure. The main characteristic used is the dominant anion or anionic group in the mineral, which determines its classification into groups such as silicates, carbonates, oxides, and sulfates. This classification helps in understanding the mineral's properties, formation, and potential uses.
The polarity of water molecules allows them to interact with the charged ions in halite (sodium chloride) and break apart the crystal structure, causing it to dissolve. Water molecules are able to surround and solvate the individual sodium and chloride ions, enabling them to be carried away in solution.
Tanzanite has a streak that is typically a light blue to violet color. Streak refers to the color of the powder produced when a mineral is scraped across a hard surface, such as a porcelain plate. This characteristic can be useful in identifying the mineral, as the streak color may differ from the color of the mineral itself. Tanzanite's streak helps to confirm its identity in mineralogy.

By rubbing mineral against a piece of porcelain tile, the objective of the test is to observe the hardness of the mineral.

When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
HCl (hydrochloric acid) in toilet cleaners helps to dissolve mineral deposits, stains, and organic matter such as bacteria and germs. It also helps to disinfect and kill pathogens to leave the toilet clean and sanitized.
Mineral spirits is a type of solvent commonly used in various applications such as cleaning paint brushes, thinning paint, and removing grease and grime from surfaces. It is a petroleum-based liquid that helps dissolve and remove substances like oil-based paints and varnishes.
