Answer:
DICLORURO DE ZINC
Explanation:
La ecuación es:
Zn (s) + 2HCl (aq) → ZnCl₂ (aq) +H₂ (g)
El zinc reacciona en una reacción redox con el acido clorhídrico para formar una sal y liberar el hidrogeno gaseoso.
Se trata de una reacción redox porque el hidrógeno se reduce (disminuye el numero de oxidación, de -1 a 0, en su estado fundamental), mientras que el Zn se oxida (el numero de oxidación aumenta de 0 a +2).
Como la sal se forma con dos atomos de cloro, se denomina dicloruro por lo que el nombre correcto de la sal en nomenclatura sistemática es:
- DICLORURO DE ZINC

A. Organic catalysts are called enzymes.
Explanation:
The true statement of all is that organic catalysts are called enzymes. For example, saliva in the mouth is made up of different enzymes which are secreted in the human body.
- Catalysts reduces the activation energy and makes reaction proceed very fast. They generally increase the rate of chemical reactions.
- Catalysts like temperature affects the rate of chemical reaction. Chemical reactions increases as temperature increases.
- Catalysts in the human body are very useful because they help chemical reactions in the body to proceed at a much faster rate.
