Answer:
X linked recessive
Explanation:
Being an X linked recessive a disorder is more prevalent in males as compared to females because a single X chromosome in male is able to expresses the trait.
In case of female untill unless there are two sets of X linked recessive allele, there will be no disorder. Infact most of the women are carrier only

Answer:
2.5 g mass of Ra-226 will remain after 4800 years.
Explanation:
Given data:
Mass of Ra-226 = 20 g
Sample remain after 4800 years = ?
Solution:
Half life of Ra-226 = 1600 years
Number of half lives passed = T elapsed / half life
Number of half lives passed = 4800 year / 1600 year
Number of half lives passed = 3
At time zero = 20 g
At first half life = 20 g/2 = 10 g
At 2nd half life = 10 g/2 = 5 g
At 3rd half life = 5 g/2 = 2.5 g
Thus, 2.5 g mass of Ra-226 will remain after 4800 years.
The shape of BeH2 is linear.
The empirical formula is CrCl₃.
Explanation:
To find the empirical formula we use the following algorithm.
We divide each percentage by the atomic weight of each element:
for Cr 32.8 / 52 = 0.63
for Cl 67.2 / 35.5 = 1.89
The result will be divined by the smallest number:
for Cr 0.63 / 0.63 = 1
for Cl 1.89 / 0.63 = 3
The empirical formula is CrCl₃.
