Su enlace es covalente apolar.
Explicación:
Ambas moléculas se unen para formar un compuesto estable, y alcanzar el "octeto".
El selenio tiene 6 electrones de valencia, y le faltaría dos electrones, para tener los 8 electrones, y así, cumplir su octeto, y volverse estable.
Por el contrario, el hidrógeno, se va a parecer al elemento noble más estable, el Helio (He), por lo cual, puede compartir sus electrones con el Selenio, así el Hidrógeno tendría 2 electrones, volviéndose estable, y el Selenio 8.
Sabiendo lo anterior, podemos calcular si es covalente polar o apolar, con una tabla de electronegatividad, que puedes encontrar en internet.
Restas el valor del Selenio al Hidrógeno, y el resultado que te de, lo comparas son los valores de referencia existentes, quedando como:
Se(2.6)-H(2.2)= 0.4
Covalente apolar: 0-0.4
Covalente polar: 0.5-1.6
The answer is C because if you put coral reefs in more places more species of fish will come in hiding it
Answer: The statement is true
Explanation:
The hypothalamus is part of the Fore-brain responsible for the secretion of hormones from the pituitary gland.
This pituitary gland situated in the hypothalamus is traditionally called the MASTER ENDOCRINE GLAND, as it influence the activities of all other glands such as thyroid gland.
Thus, the hypothalamus bearing the pituitary gland is said to be in CONTROL of the activity of the thyroid, and ALSO the master endocrine gland.
An undissolved solute, I believe.
Answer:
The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.
Explanation:
<u>Available data</u>:
- The gene for petal color in a flower has incomplete dominance
- Two A1 alleles (A1A1) express black color
- Two A2 alleles (A2A2) express white color
- One of each allele (A1A2) express mottled color
In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:
Parental) A1A1 x A1A1
Gametes) A1 A1 A1 A1
Punnet Square) A1 A1
A1 A1A1 A1A1
A1 A1A1 A1A1
F1 Phenotypes: 100% black flowers
F1 Genotype: 100% A1A1
There are 0% of probabilities of getting a mottled offspring.
