Explanation:
Cd2+ and CD(OH)2 both contain the Cd2+ specie which is chemically similar to Zn2+both being in the same group in the periodic table. Cd2+ is know to be toxic when absorbed together with Zn 2+ ions and will definitely be toxic to the aquatic species.
<em>mC: 12g/mol</em>
12g ------- 6,02·10²³ a.
6g --------- X
X = (6×<span>6,02·10²³)/12
</span><u>X = 3,01·10²³ atoms</u>
---->>> A :)
The unit expressed in 660 nm of light represents the wavelength of light. If you want to determine the frequency, you use the speed of light to relate the two. The formula is:
c = λν
where
λ is the wavelength
ν is the frequency
c is the speed of light = 3×10⁸ m
Apply SI units:
(3×10⁸ m) = (660×10⁻⁹ m)(ν)
Solving for ν,
<em>ν = 4.55×10¹⁴ s⁻¹</em>
It is based on the water underground
Because anymore water will breakdown the bonds of your Oh groups
