know nothing its b b b b bb b b b b b b b b
Step-by-step explanation:
This will be the awswer abs work
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.

False. Obtuse is always greater than 90°.
Each time x goes up by 1, y also goes up by 1 as well.
slope = rise/run = 1/1 = 1
Or we can use the slope formula to get
m = (y2-y1)/(x2-x1) = (3-2)/(2-1) = 1/1 = 1
I used the first two rows as the points to plug into the slope formula.
You can pick any two rows you want and you'll get the same slope value.

Because we get the same result of 1 each time, this means the rate of change is <u>constant</u> and this function is <u>linear</u>. Plotting all four points will show a single straight line goes through all of them. See diagram below.
