Explanation:
water evaporates because when h2o (water) particles heat up, they gain energy causing them to start to vibrate. this moves the oarticles further and further away from eachother and making the substance less dense, and turning it into a gas. meaning it has evaporated

Explanation:
The decomposition of hydrogen peroxide is:
![H_2O_2 \to H_2O + \dfrac{1}{2}O_2](https://tex.z-dn.net/?f=H_2O_2%20%5Cto%20H_2O%20%2B%20%5Cdfrac%7B1%7D%7B2%7DO_2)
![Rate = -\dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{ 2 \Delta [H_2O_2]}{\Delta t}](https://tex.z-dn.net/?f=Rate%20%3D%20-%5Cdfrac%7B%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D%3D%20%5Cdfrac%7B%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D%3D%20%5Cdfrac%7B%202%20%20%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D)
The rate of decomposition reaction = the rate of formation of
= 0.098 mol/L.s
∴
Rate of formation of
![= \dfrac{ rate \ of \ reaction }{2}](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B%20rate%20%5C%20of%20%5C%20reaction%20%7D%7B2%7D)
![= \dfrac{ 0.098 }{2}](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B%200.098%20%7D%7B2%7D)
= 0.049 mol/L.s
Answer:
<u>Higher than</u>
Explanation:
The boiling point of a solution is a colligative property
Atoms present ∝ Colligative Property <em>(Boiling Point)</em>
Since KCl is a strong electrolyte, it completely dissociates into K⁺ and Cl⁻ ions, which doubles the number of atoms as compared to what was initially added
Now it's competition is very weak, Pure water has nothing else dissolved in it. which means that our solution will have much higher boiling point as compared to Pure Water
