Answer:
4.6305 * 10^-6 mol^3.L^-3
Explanation:
Firstly, we write the value for the solubility of Ca(IO3)2 in pure water. This equals 0.0105mol/L.
We proceed to write the dissociation reaction equation for Ca(IO3)2
Ca(IO3)2(s) <——->Ca2+(aq) + 2IO3-(aq)
We set up an ICE table to calculate the Ksp. ICE stands for initial, change and equilibrium. Let the concentration of the Ca(IO3)2 be x. We write the values for the ICE table as follows:
Ca2+(aq). 2IO3-(aq)
I. 0. 0.
C. +x. +2x
E. x. 2x
The solubility product Ksp = [Ca2+][IO3-]^2
Ksp = x * (2x)^2
Ksp = 4x^3
Recall, the solubility value for Ca(IO3)2 in pure water is 0.0105mol/L
We substitute this value for x
Ksp = 4(0.0105)^2 = 4 * 0.000001157625 = 4.6305 * 10^-6
Answer:
<em>The correct option is b. new species make the environment less suitable for previous ones.</em>
Explanation:
In ecology, succession can be described as the changes in a species structure over a period of time. In a community, newer species tend to have better characteristics and adaptations to survive in a community as compared to the older ones. As a result, the new species begin to take over the land and the older ones gets removed. It is due to ecological succession that climax communities are formed from pioneer species.
You receive one allele from each parent.
<h3>Answer:</h3>
C₆H₁₄ is the only Alkane in given compounds.
<h3>Explanation:</h3>
The General Formula for Alkanes is as follow;
Cₓ H₂ₓ ₊ ₂
where;
x = whole number
It means in alkanes for every x number of carbon atoms we have 2x + 2 number of hydrogen atoms. Let's apply this formula on given compounds.
CH₂O:
As there is one carbon atom in this compound hence, the number of hydrogen atoms present for one carbon atom in alkane must be equal to,
H₂₍₁₎ ₊ ₂
H₂ ₊ ₂
H₄
Hence, this compound is not alkane because it contains only two hydrogen atoms.
C₆H₁₄:
As there are six carbon atoms in this compound hence, the number of hydrogen atoms present for six carbon atoms in alkane must be equal to,
H₂₍₆₎ ₊ ₂
H₁₂ ₊ ₂
H₁₄
Hence, this compound is alkane because it contains fourteen hydrogen atoms.
C₃H₄:
As there are three carbon atoms in this compound hence, the number of hydrogen atoms present for three carbon atoms in alkane must be equal to,
H₂₍₃₎ ₊ ₂
H₆ ₊ ₂
H₈
Hence, this compound is not alkane because it contains only four hydrogen atoms.
