Answer:
BaF2(s) ------> Ba2 (aq) + 2F- (aq)
Explanation:
Entropy refers to the degree of disorderliness in a system. Processes that lead to greater disorderliness in a system are said to increase the entropy of the system or lead to a positive value of ΔS.
If we consider the process, BaF2(s) ------> Ba2 (aq) + 2F- (aq), we will notice that ions were produced in solution thereby increasing the disorderliness of the system.
Answer:
The child with the trait is heterozygous.
Explanation:
It's a little difficult to be sure without wider context. But my interpretation of both the graphic and the wording, is that the circle represents a person who has the trait, but not necessarily someone who expresses the trait. The square, on the other hand, seems to represent a person who does not have the trait at all.
Based on that, the squares would be hom-zygous--they possess two copies of a dominant version of the characteristic. And the circles would be heteroxygous--they possess two different versions, one recessive and one dominant.
Unfortunately, this is actually a poorly constructed question, and if the circles are intended to represent an individual who <em>expresses </em>the recessive trait, then the answer would be that the child is hom-zygous. But based on the exact wording of the question, the correct interpretation of the graphic should be as I've explained above.
