Answer:
Everyone, this is Ricky. And today we're working on Problem 51 from Chapter 22 and we're gonna determine the number of UNP. Aired electrons for the complex island of CEO seal for minus two I first up, let's determine the charge of art metal ion. So cue is our charge plus four minus one, which is a charge of each chloride ion. The overall charge of minus two Hugh is equal to plus two. I hope this will help
Answer: 
Explanation:
As we know that,
![-[m_1\times c_1\times (T_{final}-T_1)]=[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=-%5Bm_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%5D%3D%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
.................(1)
where,
q = heat absorbed or released
= mass of metal = 100.0 g
= mass of water = 100.0 g
= final temperature = 
= temperature of metal = 
= temperature of water = 
= specific heat of metal = ?
= specific heat of water= 
Now put all the given values in equation (1), we get
![-[100.0\times c_1\times (80-600)]=[100.0\times 4.2\times (80-30)]](https://tex.z-dn.net/?f=-%5B100.0%5Ctimes%20c_1%5Ctimes%20%2880-600%29%5D%3D%5B100.0%5Ctimes%204.2%5Ctimes%20%2880-30%29%5D)
Therefore, the specific heat capacity of metal is
