For each of the salts on the left, match the salts on the right that can be compared directly, using ksp values, to estimate solubilities. if more than one answer is correct, enter the letters without delimiting characters. 1. barium sulfite

a. ag2so3 2. lead iodide

b. pbso4

c. pbcro4

d. nis write the expression for ksp in terms of the solubility, s, for each salt, when dissolved in water. barium sulfite lead iodide ksp = ksp =

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
