Answer:
D. concentration, as the concentrations of reactants and products remain unchanged after equilibrium is reached.

I put it for the test and i got right hehe
Answer: The donating of hydrogen ions is what makes an acid an acid. A base, however, is a substance that accepts hydrogen ions.
Explanation:
You know that each carbon atom can take as much as 4 bonds with other elements. A hydrogen can only take one bond, while an oxygen can take 2. Thus, the chemical formula of H₂CO may be written as H₂C=O which is acetaldehyde. Acetaldehyde is an aldehyde. It has a higher vapor pressure because aldehydes have much stronger bonds than hydrogen bonds in alcohols. Hence, it would need a lot energy, thus higher vapor pressure, to break the bonds of an aldehyde than it would for an alcohol.
Sodium has a noble gas configuration, plus a single high energy 3s1 electron. This electron is more stable when associated with more electronegative atoms and polyatomic ions. Therefore, sodium loses a single electron (losing a negative charge, granting the sodium atom a +1 charge). Positive and negative charges attract each other in order to balance out the charge (reach a low energy state), so two +1 sodium atoms need to associate with either two separate -1 charges, or a single -2 charge. The only polyatomic listed here that satisfies the -2 (formally written 2-) needed to attract both sodium atoms is the Carbonate ion, CO3(2-).
Dominant allele
Explanation:
An allele whose trait shows up in an organism when the allele is present is called a dominant allele.
An allele whose trait does not show up in an organism when present is called a recessive allele.
- An allele is the two possible forms of gene.
- A gene can be dominant or recessive in nature.
- An allele is a DNA that occupies a particular locus on a chromosome.
- They usually occur in pairs.
- The allele determines hereditary characteristics.
