A 1.0 l buffer solution is 0.15 m in hcn and 0.10 m in nacn. which action will destroy the buffer?
rjkz [21]

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.

Which of these is an exponential parent function?
kipiarov [429]

Complete question is;

Which of these is an exponential parent function?

A. f(x) = x

B. f(x) = 2^(x)

C. f(x) = x²

D. f(x) = |x|

Answer:

B. f(x) = 2^(x)

Step-by-step explanation:

> In option A, f(x) = x

This function depicts a straight line with intercept as 0 and slope as 1.

> In option C, f(x) = x²

This function depicts a parabola open up since the leading coefficient is greater than 0.

> In option D: f(x) = |x|

This function depicts a straight line y = x for x > 0 and y = -x for x < 0

In option B f(x) = 2^(x)

This function depicts an exponential function because the x is in the exponent form with a base of 2.

Answer ASAP! Which statement best illustrates using the vertical line test to determine if the graph below is a function of x?
vlabodo [156]

Answer: is If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.

Step-by-step explanation: answer is A

A battery requires 120.0 amps of electricity to fully charge. How many amps are required to fully charge the battery 25 times? (
gogolik [260]
I don't understand why the battery needs 120 amps of current to charge. But if that's what it takes, then the same 120 amps will charge it each time.
