Answer:
0.4912 kJ/K
Explanation:
Using steam table, the properties of water at stage 1 can be determined:
= 400 kPa
= 60°C
Therefore, from steam table:
specific volume 
entropy 
Calculating the specific volume of water after the partition is removed, since the mass is constant and volume of water is doubled:
Final pressure of water in the tank = 
dryness factor after removing the partition
Therefore:
Thus, the entropy change is:
Δs = 
Therefore, the entropy change of water is 0.4912 kJ/K
Answer:
false
Explanation:
this is because , high temperature speeds up the the random motion of particles which leads to high dissolution
It’s the elements that weigh the most are created when the events!

Answer:
4.63 moles of CCl4
Explanation:
C + 2Cl2 = CCl4
The balanced equation tells us that we'll obtain 1 mole of CCl4 for every 1 mole of C, assuming we have 2 or more moles of Cl2 (which we do in this problem).
Therefore, if we start with 4.63 moles of C, we'll produce 4.63 moles of CCl4
