Explanation:
To tract genetic inheritance ( phenotype or genotype) from one generation to another generation, PEDIGREE CHART is used. Pedigree Chart is a diagram shows the occurrence and appearance of a particular genes of an individual organism from its ancestor down to the generations it follows. Relationship in a pedigree is shown as a series of linear graph. Parents are connected to a horizontal lines while vertical lines will lead to the offspring.
Answer:

Atomic Number 40
Atomic Mass 91.224 atomic mass units
Number of Protons 40
Number of Neutrons 51
Explanation:
The bond<span> length in a </span>molecule<span> of </span>KBr<span> is measured to be 282.1 pm, compared with a </span>nonpolar<span> covalent radius sum for K and Br of 310,4. </span>
The balanced chemical reaction is written as:
<span>Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)
</span>
We are given the amount of the reactant zinc to be used in the reaction This amount would be the starting point for the calculation. It is as follows:
5.00 mol Zn ( 1 mol H2 / 1 mol Zn ) (2.02 g H2 / 1 mol H2 ) = 10.1 g H2
Therefore, the correct answer is the second option.
