Answer:
= 25 %
Explanation:
Given that :
the genotype attributed to trolls having one eye = (EE, Ee); that is homzygous dominant or heterozygote dominant for eye number
Likewise those that posses two eyes have (ee) ; that is homzygous recessive
Now; two heterozygous one eyed trolls are crossed ; we have :
Ee × Ee
The punnet square for this cross looks like what we have below:
E e
E EE Ee
e Ee ee
From the above cross; we have:
1 EE ---- (homozygous dominant ) indicating troll having one eye
2 Ee ---- ( heterozygote dominant ) indicating troll having one eye
1 ee ----- ( homozygous recessive ) indicating troll having two eyes
The genotypic ratio is 1:2:1
Thus; the expected genotype ratio of the two eyed offspring =
= 25 %
Moles of CuS : 1.2
<h3>Further explanation</h3>The reaction coefficient in a chemical equation shows the mole ratio of the components of the reactants and products
If one mole of the reactant or product is known, then we can determine the moles of the other compounds involved in the reaction
Reaction
<em>CuCl₂ (aq) + H₂S (g) → CuS (s) + 2HCl (aq)</em>
CuCl are mixed with excess of H₂S gas, so CuCl as a limiting reactant
mol ratio of CuCl₂ : mol CuS = 1 : 1, so mol CuS :
