When kinetic energy is increasing molecules are simply moving faster. However, when the potential energy is increasing molecules are changing phases. Therefore, when the potential energy is increasing is when the molecule is changing phases

Energy is required to change the phase of a material, with the change in energy either it decreases or increases. When the phase is changed, the temperature and kinetic energy does not change it stays the same but the internal energy changes

Answer:

Hello, Im Mack. Hope you're doing well. :)

Here is my Correct, custom answer for the lab Question, (I also took the same assignment and got a 100% score)

Explanation:

The heating of the sodium acetate solution made it change from super-saturated to un-saturated. Yet now that it cooled back to room temperature Im sure it is saturated. it wasn't able to disolve the excess sodium acetate left over at room temperature and had to be heated so now that it is back to room temperature I Think it will not disolve the sodium acetate left in the solution until it is heated again.    

Hope this helped you out,

Please feel free to comment for further help, and I'll reply asap.

<u>Have a great day my friend :)</u>

An element initially weighed 3.555 g. When it was burned in oxygen an oxide compound was produced. The product mass was 4.666 g.
lesya692 [45]
A)
The additional mass is that of Oxygen
4.666 - 3.555
= 1.111 g
B)
The percentage mass of oxygen can be obtained by:
[(mass of Oxygen)/ (Total mass of product)]  * 100
= (1.111 / 4.666) * 100
= 23.81%
