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.

Explanation:
La ciencia puede entenderse como una forma que el ser humano encontró para adquirir conocimientos a través de métodos científicos, tecnológicos y basados en estudios, pruebas e investigaciones y no basados en el pensamiento para explicar los fenómenos humanos, de la naturaleza y de la vida.
La ciencia tiene un rol impactante y transformador en la sociedad, todo el conocimiento adquirido por el hombre a través de la ciencia ha transformado para mejor la vida de las personas, generando mayor calidad de vida, salud, educación, sentido crítico, etc.
En el escenario pandémico que vive el mundo actualmente, la ciencia es fundamental, a través de sus estudios e investigaciones que han ayudado en el desarrollo de vacunas efectivas para inmunizar a los humanos contra el virus y salvar vidas.
5Fe2(SO4)3 + K2SO4 + 2MnSO4 + 8H2O
Answer:
NH₄CN, NH₄IO₃, Fe(CN)₃, Fe(IO₃)₃
Explanation:
Cations (positively charged ions) can only form ionic bonds with anions (negatively charged ions). However, you can't just simply put one cation and one anion together to form a compound. Each compound needs to been neutral, or have an overall charge of 0. When cations and anions do not have charges that perfectly cancel, you need to modify the amount of each ion in the compound.
1.) NH₄CN
-----> NH₄⁺ and CN⁻
-----> +1 + (-1) = 0
2.) NH₄IO₃
-----> NH₄⁺ and IO₃⁻
-----> +1 + (-1) = 0
3.) Fe(CN)₃
-----> Fe³⁺ and CN⁻
-----> +3 + (-1) + (-1) + (-1) = 0
4.) Fe(IO₃)₃
-----> Fe³⁺ and IO₃⁻
-----> +3 + (-1) + (-1) + (-1) = 0
