A buffer is made with sodium acetate and acetic acid

SAT
1 answer:
tamaranim1 [39]2 years ago
3 0

Answer:

Because Water is not a buffer solution and the acetic acid/acetate solution is a buffer solution. An acidic buffer is a solution of a weak acid (acetic acid) and its conjugate base pair (sodium acetate) that prevents the pH of a solution from changing drastically through the action of each component with incoming acid or base.

Describe the sounds, smells, and sights you associate with spring. Write a paragraph with at least 4 sentences.
spin [16.1K]
Smell: Spring brings soothing scents like lilacs, apple blossoms, hyacinth and daffodils. Sweet aromas turn a stroll through the garden into a delicacy for the nose Springtime means that the trees and flowers come back to life again. After a dead winter, this is a time when we get to see the beautiful flowers blossom again Spring also brings new sounds, like bird songs at dawn, frog croaks by ponds, and dripping icicles. When the weather warms, the sounds you hear in national parks reflect this seasonal change (use this but not in this order fix it up a bit)

What it means that [If x is a factor of p(x), what is the value of k?]
kompoz [17]

Answer:

k = -4

Explanation:

Given

P(x) = (3x^2 - 5)(x + k) - 20

x is a factor

Required

Solve for k

x is a factor means that the polynomial can be divided successfully by x.

In other words, x is a zero of the polynomial.

i.e.

x = 0 and P(x) = 0

Substitute 0 for x in P(x)

P(x) = (3x^2 - 5)(x + k) - 20

P(x) = (3*0^2 - 5)(0 + k) - 20

P(x) = (0- 5)(k) - 20

P(x) = (-5)(k) - 20

P(x) = -5k - 20

Substitute 0 for P(x)

0 = -5k - 20

Collect Like Terms

5k = - 20

Divide both sides by 5

k = -4
