Answer:The reaction absorbs 8100 J of energy from the surroundings as it proceeds.
Explanation:
Answer:
<span>Formula for sodium hydroxide is represented by <u>NaOH</u>.
Explanation:
The reaction of Sodium oxide with water is as follow,
Na</span>₂O + H₂O → 2 NaOH
<span>

the correct answer is dissapate...but it is
not here so i think relativly the answer is destroy
When you boil water, you aren't changing the elements. You're just making water vapor. However, when you burn paper, it becomes carbon (mostly). So physical changes will not change the substance, only chemical changes will.
Methanol is the substance that can be broken down by chemical means, the remaining ones are elements.
