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:
Henry does not make money if he does not sell any apples.
Step-by-step explanation:
Henry sells apples. The graph of the relationship between the price of apples and their total weight passes through the point (0,0) or origin.
Now, we have to clarify the meaning of the point (0,0) on the graph.
We choose from the options that Henry does not make money if he does not sell any apples.
Therefore, option D will be the correct one. (Answer)
Answer: No solution
<u>Step-by-step explanation:</u>
1st number: x
2nd number: x + 2
- reciprocal of the larger is
- 4 times the reciprocal of the smaller is 4
- reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller is 4 -
- the result is 56: 4 - = 56
Solve the equation:
4 - = 56
- 
= 56(x(x + 2))
4x + 8 - x = 56x² + 112x
3x + 8 = 56x² + 112x
0 = 56x² + 109x - 8
Use the quadratic formula to solve:
x = 
The result is NOT AN INTEGER so there is NO SOLUTION
Answer:
Middle School In Favor: 25%
Middle School Not in Favor: 75%
High School In Favor 20%
High School Not In Favor 80%
Step-by-step explanation:
For the middle school in favor, we need to find the percent, which is 50 out of 200, so its 1/4, 25%
So the rest of the middle school is not in favor, which is 75%
High school is 60 not in favor, so we need to find the percentage. So 60 out is 300 is 20%
And we just subtract 20 from 100 which leaves us with 80
