The buffer will probably be destroyed by the addition of HCN.
<h3>What is buffer solution?</h3>
A weak acid and the conjugate base of the weak acid, or a weak base and the conjugate acid of the weak base, are combined to form the buffer solution, a water-based solvent solution. They withstand being diluted or having modest amounts of acid or alkali added to them without changing their pH.
Given that a 1.0 l buffer solution is 0.15 m in HCN and 0.10 m in NaCN.
We need to find a action which one destroy the buffer solution.
A buffer is a substance made of salt and a weak acid that is beneficial. From the aforementioned chemicals, HCN is a potent acid and NaCN is a salt between HF and NaCN. Therefore, the buffer will probably be destroyed by the addition of HCN.

Answer:
23
Step-by-step explanation:
We are given that
f(2)=13
We have to find the possible small value of f(7).
We know that
Using the formula
We have
The small value of f(7) can be 23.
Answer:
97.2
Step-by-step explanation:
4 1/2 = 4.5
7 1/5 = 7.2
4.5x7.2x3 = 97.2
The volume is 97.2

The place value of the 5's in 6755 reading from left to right is the first 5 is in the tens place and means 50 because 5x10=50. The second 5 is in the ones place and stands for 5 because 5x1=5.
