Explain how mendal experiments with seed colors disapproved the common belief of blending inheritance

Chemistry
1 answer:
Elan Coil [88]4 years ago
6 0
The theory of blending inheritance was used to describe an actual blending of our alleles, that together would form a new allele. For example, skin color and height would be the result of the blend of the parent's alleles.
This theory doesn't explain why some traits disapear or are discrete.
On the other hand, Mendel's experiments with seed colors explains it. He demonstrated that genes are inherited in pairs and that in hybrid organisms, dominant versions of that gene, could hide the presence of a recessive version of that same gene.

Calculate the mass, in grams, of Al(OH)3 required for this reaction:
AVprozaik [17]

Answer:

Mass = 28.08

Explanation:

Given data:

Mass of Al₂O₃ = 21.8 g

Mass of water = 9.7 g

Mass of Al(OH)₃ = ?

Solution:

Chemical equation:

2Al(OH)₃   →   Al₂O₃ + 3H₂O

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 9.7 g/ 18 g/mol

Number of  moles = 0.54 mol

Number of moles of Al₂O₃:

Number of moles = mass/molar mass

Number of moles = 21.8 g/ 101.96 g/mol

Number of  moles = 0.21 mol

Now we will compare the moles of Al(OH)₃ with  Al₂O₃ and H₂O.

                          Al₂O₃       :          Al(OH)₃

                             1            :              2

                         0.21          :         2×0.21 = 0.42 mol

                         H₂O          :            Al(OH)₃

                            3            ;             2

                          0.54        :        2/3×0.54 = 0.36 mol

Mass of Al(OH)₃:

Mass = number of moles × molar mass

Mass = 0.36 mol × 78 g/mol

Mass = 28.08 g
