A . Luminosity versus temperature
Answer:
Explanation:
Hello,
In this case, for the reaction:
We notice it is undergone as heterogeneous equilibrium, that is why, for the thermodynamic equilibrium constant we consider the aqueous species only, that is the concentration of A to the second power (stoichiometric coefficient) only:
Thus, the equilibrium constant turns out:
Clearly, B, C, D and E are not considered as they are gaseous, liquid, solid and gaseous respectively, and based on the procedure to write the law of mass action, they are not considered due to different phases.
Best regards.
Answer:
a. CH3NH2(aq) + H⁺ → CH3NH3⁺
Explanation:
The mixture of a weak base as CH3NH2 with its conjugate acid CH3NH3Cl produce a buffer. As the weak acid is in equilibrium with water, the mixture of the weak base and its conjugate base produce that the acid or base released react avoiding the change in pH.
For example, when a strong acid as HNO3 reacts, the weak base will react producing the conjugate base, that is:
CH3NH2(aq) + H⁺ → CH3NH3⁺
Right answer is:
<h3>a. CH3NH2(aq) + H⁺ → CH3NH3⁺</h3>
<h3><u>Answer;</u></h3>
- Nitrogen is a macronutrient in plants.
- Nitrogen-fixing bacteria in the soil convert N2 to NH3.
- Nitrogen is a component of nucleic acids, proteins, hormones, and coenzymes.
- Plant roots can only absorb nitrogen in the form of ammonium ions (NH4+) or nitrate ions (NO3-)
<h3><u>Explanation;</u></h3>
- Macronutrients are elements that are taken in large amounts by the plants, they include; nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.
- Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia.
- Plants absorb nitrogen from the soil both in the form of nitrate (NO3−) and ammonium (NH4+).
- Nitrogen is an essential element to form amino acids, proteins, nucleic acids, coenzymes and chlorophyll.
