A
Explanation:
In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes
Answer:
It's temperature drops, and if releases thermal energy
500 J (I've had the same question before so I know what answers there are... lol)
Salts in order of growing pH of their 0.1 M aqueous solutions: NaHCO₃, , NaHSO₄ , Na2CO3, NH₄NO₃ .
<h3>How do you determine the pH of a substance?</h3>
To calculate the pH of an aqueous solution you want to recognize the attention of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
<h3>What makes a salt acidic?</h3>
Since the cation acts as weak, a salt with an anion of a strong acid and a cation of a susceptible base produces an acidic solution with a pH much less than 7.
In this case, the anion will become the spectator ion, while the weak acid dissociates in water and yields H3O+ ions.

Answer:
C) hydrogen bonds
Explanation:
The abnormally high boiling point of HF compared to HCl is primarily due to the intermolecular forces called hydrogen bonds.
Hydrogen bonds are intermolecular forces of attraction between polar molecules in which a hydrogen atom is directly joined to a highly electronegative atom (oxygen, nitrogen or fluorine).
Hydrogen bonds are very strong force of attraction compared to dipole - dipole attraction that holds the HCl together.
