Question

identify the chemical reactions as endothermic, exothermic, or neither. an egg cooking: a candle burning: plaster and water combining and becoming warm: salt being added to water, with no change in temperature:

Explanation:

• An egg cooking requires heat input, so it's endothermic.
• A candle burning releases heat, so it's exothermic.
• Plaster and water combining and warming up release heat, so it's exothermic.
• Salt added to water with no temperature change is neither endothermic nor exothermic in a significant way for this context.

Answer:

• An egg cooking: Endothermic
• A candle burning: Exothermic
• Plaster and water combining and becoming warm: Exothermic
• Salt being added to water, with no change in temperature: Neither
