The lower case letter represents the recessive allele.
Answer:
E) This is not an Oxidation/ Reduction type of reaction
Explanation:
Oxidation involves the loss of electrons while reduction involves the addition of electrons. None of the elements change their oxidation number in the reaction, so this is not an oxidation/reduction type of reaction.
Answer:
S²⁻(aq) + Cr²⁺(aq) ⇄ CrS(s)
Explanation:
The molecular equation includes all the species in the molecular form. Usually, it is useful to write this first to balance the equation. This is a double displacement reaction.
K₂S(aq) + Cr(NO₃)₂(aq) ⇄ 2 KNO₃(aq) + CrS(s)
The full ionic equation includes all ions and the species that no dot dissociate in water.
2 K⁺(aq) + S²⁻(aq) + Cr²⁺(aq) + 2 NO₃⁻(aq) ⇄ 2 K⁺(aq) + 2 NO₃⁻(aq) + CrS(s)
The net ionic equation includes only those ions that participate in the reaction and the species that do not dissociate in water.
S²⁻(aq) + Cr²⁺(aq) ⇄ CrS(s)
To find the mean of a number of numbers, First you add them up.
9.99 + 10.01 + 9.97 + 10.8 = 40.77
Then, you divide the result by how much numbers you have (in this case 4)
40.77 / 4 = 10.1925
So, the mean value is 10.1925.
The deviation is the difference between the number and the mean.
(number - mean = Average deviation)
So you get:
9.99 - mean = 9.99 - 10.1925 = -0.2025
10.01 - 10.1925 = -0.1825
9.97 - 10.1925 = -0.2225
10.8 - 10.1925 = 0.6075
Now to find the Average deviation, you do the same steps as finding the mean. Add them up, and divide by 4 (because there is 4 numbers)
P.S. Negative numbers become positive.
0.2025 + 0.1825 + 0.2225 +0.6075 = 1.215
1.215 / 4 = 0.30375
So, the Average Deviation is 0.30375
Hope this Helps :)
