Explanation:
Manganese is a group 7 transition metal with an electronic configuration of [Ar] 3d5 4s2.
Answer:
H20
water (the chemical symbol, as used in non-specific contacts. 8 equals hydrogen equals oxygen and two elements in hydrogen therefore is known as H2O .
H202
hydrogen peroxide equals hydrogen peroxide is the chemical compound with formula h202. And it's your form, it is very pale blue liquid, slightly more vicious than water. It is used as an oxidizer, bleaching agent, and antiseptic .
Co=
carbon monoxide, carbon monoxide is colorless, odorless, and tasteless flammable gas that is slightly less dense than air. Formula equals Co
Answer:
i think b is the answer hope this helps:))
Answer:
The concentration of the solution is 1.068×10⁻⁴M
Explanation:
Hello,
To find the concentration of the solution, we'll have to use Beer-Lambert law which states absorption is directly proportional to the concentration of the solution.
Beer-Lambert law = A = εCL
A = absorption = 2 - log₁₀%T = 2 - log₁₀(34)
A = 2 - 1.5314 = 0.47
A = 0.47
ε = molar absorption coefficient = 4400
C = concentration of the solution
L = path length = 1cm
A = εcl
C = A / εl
C = 0.47 / 4400 × 1
C = 1.068×10⁻⁴M
The concentration of the solution is 1.068×10⁻⁴M
