The material that is part of the system that absorbed heat is : The water
<h3>Endothermic reaction </h3>
During Endothermic reactions heat is absorbed from the surroundings therefore the container becomes cold when touched as seen in the experiment.
The ammonium nitrate after been poured into the water at room temperature is not evenly distributed but after stirring with the stirring rod it becomes evenly distributed and its heat is been absorbed by the water, which causes the container to become cold to touch instead of becoming hot due to the high temperature of ammonium nitrate.
Hence we can conclude that The material that is part of the system that absorbed heat is : The water

Answer: Conservation of energy
Explanation:
The law of conservation of energy or the first law of thermodynamics states that energy cannot be created or destroyed but can be transformed from one state to another. It can be transformed from Potential energy to Kinetic energy, to chemical energy, to mechanical energy and so on.
In the case above the condensation of ADP an inorganic phosphate stored up 32kJ of energy as ATP (potential energy). The hydrolysis of ATP to ADP and inorganic also releases 32kJ of energy (kinetic energy) the same value of energy that was initially stored up. This means that energy is been conserved.
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
