Answer:
Therefore, the rate of change in the amount of salt is 

Explanation:
Given:
Initial volume of water
lit
Flowing rate = 5 
The rate of change in the amount of salt is given by,
( Rate of salt enters tank - rate of sat leaves tank )
Since tank is initially filled with water so we write that,

Let amount of salt in the solution is
,


Therefore, the rate of change in the amount of salt is 

Answer:
i would say the the first 1
Explanation:
Answer:
12.9
Explanation:
From the question given, the concentration of the hydroxide ion is given:
[OH^-] = 1.4 x 10^ -13M
pOH =?
pOH = —Log [OH^-]
pOH = —Log 1.4 x 10^ -13
pOH = 12.9
