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:
We can use trigonometric ratios to solve this

Using a cosine calculator we find that cos(24)=0.91354546 and 0.91354546 x 5=4.56
GH=4.5677273 or 4.57 rounded
Step-by-step explanation:
Answer:
5, 25
Step-by-step explanation:
When you multiply any two whole numbers with each other and get 125 as the answer, you can say that both the numbers will be the factors of 125. 1× 125 = 125 and 5 × 25 = 125; thus, the factors of 125 are 1, 5, 25, and 125.
