Answer:
The four are Ll
The four will have long feathers
Explanation:
A Punnett square is a graphical representation of all possible genotypes of an offspring that is likely to arise from a particular cross or breeding event. To create a Punnett square, knowledge of the genetic composition of the parents is highly required. The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. In its simplest form, the Punnett square consists of a square divided into four quadrants. A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.
The genotypes of the four offsprings are Ll, Ll, Ll and Ll. This implies that they are all heterozygous. They will all have long feathers since the long feather (L) is dominant in all the species. In terms of phenotype, they will all have long feathers.
Mass of MnO2 = 25 g
The reaction would be 3MnO2 + 4Al --> 3Mn(s) + 2Al2O3
Molar mass of Al = 26.982 g/mol
Molar mass of MnO2 = 54.938 + 2(15.999) = 86.936 g/mol
Calculating the moles = 25 / 86.936 = 0.2876 mol.
Mole ratio MnO2 and Al considering the equation = 3 mol of MnO : 4 mol of Al
Calculating the moles of Al = 0.2876 mol MnO2 x (4 mol of Al / 3 mol of MnO)
Number of moles of Al = 0.3834
Getting the mass in grams as asked = 0.3834 mol x 26.982 g/mol = 10.34 grams.
Explanation:
Two different elements have similar chemical properties when they have the same number of valence electrons in there outermost energy level. Elements in the same column of the periodic table have similar chemical properties.
An alloy<span> is a mixture of metals, or a mixture of metal along with another element. </span>Alloys<span> are defined by a metallic bonding character. An </span>alloy<span> may be a solid </span>solution<span> of metal elements, (a single phase) or a mixture of metallic phases (two or more </span>solutions<span>).</span>
