Your answer is B. Acid rain might destroy ecosystems and farmland
The molar extinction coefficient is 15,200 .
The formula to be used to calculate molar extinction coefficient is -
A = ξcl, where A represents absorption, ξ refers molar extinction coefficient, c refers to concentration and l represents length.
The given values are in required units, hence, there is no need to convert them. Directly keeping the values in formula to find the value of molar extinction coefficient.
Rewriting the formula as per molar extinction coefficient -
ξ =
ξ =
Performing multiplication in denominator to find the value of molar extinction coefficient
ξ =
Performing division to find the value of molar extinction coefficient
ξ = 15,200
Hence, the molar extinction coefficient is 15,200 .

#SPJ4
Which list of elements contains a metal, a metalloid, and a nonmetal?(1) Zn, Ga, Ge (3) Cd, Sb, I(2) Si, Ge, Sn (4) F, Cl, Br
Sladkaya [172]
3) Cd . Sb . I
<span>look at the periodic chart- if the element is on the right it is a nonmetal, if it is on the left its a metal, and if it is in between it is a metalloid</span>
Gravity
Explanation:
The unpowered cars as shown gets their potential energy from their acceleration due to gravity and the height above the ground of the hill.
Potential energy is the energy due the position or a body. It is energy primarily at rest of a body.
Potential energy = m x g x h
Where:
m = mass
g = acceleration due to gravity
h = height of the hill.
