<span>Galvanized steel is preferred for outdoor uses because it is ideal to prevent rotting/corrosion
A steel will rot more quickly if it's exposed to a larger amount of oxygen and H2O , which will exist if we put it oudoor
Coating the steel with additional zinc will slow down the process</span>
Answer:
If the pH of a solution is less than 7, the solution is called acidic; if the pH is about 7, the solution is neutral; if the pH is greater than 7, the solution is is called basic. In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions.
Explanation:
Answer: In atoms, there are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).
Just study it by looking it up
Hydrothermal metamorphism involves chemical reactions between oceanic lithosphere and warm fluids near mid-ocean ridges
Hydrothermal metamorphism is most common along mid-ocean ridge spreading centers, where warm seawater percolates through hot, cracked basalt. Metamorphism of basalt occurs as a result of chemical interactions between hot saltwater and basalt. On continents, crustal rocks can be metamorphosed by invading, hot fluids associated with igneous intrusions, resulting in hydrothermal metamorphism.
The interaction of a rock with a high-temperature fluid of changing composition results in hydrothermal metamorphism. The compositional mismatch between an existing rock and the entering fluid causes a series of metamorphic and metasomatic processes.
Hydrothermal metamorphism changes Mg-Fe-rich hydrous minerals like talc, chlorite, serpentine, actinolite, tremolite, zeolites, and clay minerals. Hydrothermal metamorphism is frequently responsible for the formation of rich ore deposits.
