Answer:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Explanation:
We are to give the reaction expression for this displacement reaction.
Reactants = copper and silver nitrate solution
Products = silver and copper (II) nitrate
Copper = Cu
Silver nitrate solution = AgNO₃
Silver = Ag
copper (II) nitrate = Cu(NO₃) ₂
So:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Answer: Neutral Value
Explanation: pH of the blood is maintained at 7.0 to 7.5that is neutral value.
This is because if the pH of the is lower than the maintained value then it will become acidic .
Acidic pH can cause the medical urgency known as acidosis leading to vomiting, diarrhea etc.
If the pH becomes higher, then the blood will become basic in nature and it can also leas to the death of the person.
That is why the pH of the blood is maintianed at neutral value of 7.0 to 7.5
Answer: 5 Liters
Explanation:
According to the dilution law,
where,
= concentration of first solution = 24%
= volume of first solution = x L
= concentration of second solution = 14%
= volume of second solution = (10-x) L
= concentration of final solution = 19%
= volume of final solution = 10 L
Putting i the values, we get:
Therefore, 5 Liters of the 24% acid solution are used to make 10 liters of the 19% acid solution.
