drag each tile to the correct location. classify the reactions as endothermic or exothermic. the reaction between ammonium nitrate and water absorbs heat from the surrounding environment. three drops of concentrated sulfuric acid added to 100 milliliters of water in a beaker makes the beaker hot. ammonium chloride dissolved in a beaker of water makes the beaker cold. uranium atoms are split to produce nuclear energy. water separates into hydrogen and oxygen when an electric current is run through it. methane and oxygen are combined to produce methanol and heat. endothermic reaction exothermic reaction
Answer
Brief Explanations:
- Endotérmicas: Las reacciones endotérmicas absorben calor del entorno. El reaccionar ammonium nitrato con agua, disolver ammonium cloruro en agua y la descomposición de agua en hidrógeno y oxígeno con corriente eléctrica son endotérmicas porque absorben calor (hacen que el recipiente se enfríe o requieren energía externa).
- Exotérmicas: Las reacciones exotérmicas liberan calor al entorno. Añadir ácido sulfúrico concentrado a agua, la fisión de átomos de uranio y la combinación de metano y oxígeno para formar metanol y calor son exotérmicas porque liberan calor (hacen que el recipiente se caliente).
Answer:
Endothermic Reaction:
- The reaction between ammonium nitrate and water absorbs heat from the surrounding environment.
- Ammonium chloride dissolved in a beaker of water makes the beaker cold.
- Water separates into hydrogen and oxygen when an electric current is run through it.
Exothermic Reaction:
- Three drops of concentrated sulfuric acid added to 100 milliliters of water in a beaker makes the beaker hot.
- Uranium atoms are split to produce nuclear energy.
- Methane and oxygen are combined to produce methanol and heat.
