The planet Gallifrey has two naturally occurring isotopes of chlorine. Chlorine-35 has an isotopic abundance of 45.89% and a mas

s of 34.9689 amu. Chlorine-37 has an isotopic abundance of 54.11% and a mass of 36.9659 amu.

Answer:

36.05 amu

Explanation:

Given data

Isotope       Mass (m)               Abundance (ab)

³⁵Cl              34.9689 amu        45.89% (0.4589)

³⁷Cl              36.9659 amu        54.11% (0.5411)

We can calculate the average atomic mass (am) of chlorine on planet Gallifrey using the following expression.

am = ∑ mi × abi

am = 34.9689 amu × 0.4589 + 36.9659 amu × 0.5411

am = 36.05 amu

What does it mean to say B is representing the dominant gene
Degger [83]

Answer:

Dominant genes are always represented by a capital letter which in this case is the letter B whereas recessive genes will be represented by a lower case letter like b.

You only need one copy of a dominant gene or allele to inherit it. A dominant allele is always expressed even if only one copy is present.

But you need two copies of genes or alleles to inherit the recessive gene. There also can't be a dominant allele of the gene if you are to inherit this.

The absorbance of a garbanzo bean solution that had been diluted by a factor of three was 0.528. what was the concentration of t
Serjik [45]
The Beer-Lambert law states that A = E*c*l where A is absorbance, E is the molar absorbance coeffecient, c is concentration and l is path length. Therefore the absorbance is directly proportional to concentration, and by increasing the concentration by a factor of 3, absorbance will increase by a factor of 3 giving   A = 1.584

How do chemical weathering and physical weathering affect each other?
Zinaida [17]
Both processes occur in place. No movement is involved in weathering. Chemical weathering involves a chemical change in at least some of the minerals within a rock. Mechanical weathering involves physically breaking rocks into fragments without changing the chemical make-up of the minerals within it.
