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.
The answers that apply are;
- gas molecules are closer together
- air weighs more
- air is hotter
When air is compressed, it means the same volume of space is occupied by more air molecules. This, therefore, means that the molecules are hitting each other with a higher frequency hence become hotter with more compression. It weighs more because there are more molecules in the same volume of space.
Answer:
The value of equilibrium constant is 29.45.
Explanation:
Moles of hydrogen gas = 2.00 mol
Concentration of hydrogen gas =
Moles of iodine gas = 1.00 mol
Concentration of iodine gas =
initially
2.00 M 1.00 M 1.00 M
At equilibrium:
(2.00-x/2) (1.00-x/2) x
Moles of HI at equilibrium = 1.80 M
Concentration of HI at equilibrium =
The expression of an equilibrium constant is given by ;
Putting x equal to 1.80 M.
The value of equilibrium constant is 29.45.
According to the formula of vapor pressure:
Pv(solu) = n P°v(water)
when we have Pv(solu) = 23.1 torr & Pv(water) = 23.8 torr so we can get the mole fraction of water (n)
∴ n = Pv(solu) / Pv(water)
= 23.1 / 23.8 = 0.97 mol
when mole fraction of water = moles of water / (moles of water + moles of glucose)
So by substitution::
0.97 = 27.78 / (27.78+ X)
∴moles of gulcose = 0.85 mol
∴ mass of glucose = no.of moles * molar mass
= 0.85 * 180 = 152 g
