Answer:
The process is called Nitrogen fixation
Explanation:
The nitrogen fixation is a process carried out by some prokaryotic microorganisms (bacteria), specifically those have the presence of the nitrogenase enzyme. The bacteria absorb the atmospheric nitrogen (N2) from the roots of plants, and the nitrogenase enzyme, with the help of two proteins that act as electron donors and acceptors (nitrogenase complex) reduce the nitrogen to ammonia (NH3), then the ammonia is ionized to NH4+ (ammonium). Followed by that, the ammonia is oxidated to nitrates and nitrites, which are finally absorbed again by plants.
b. The mass of the Carbon-14 sample is greater than the Carbon-12 sample, but the reactivity of both samples was the same .
c. The reactivity of the Carbon-14 sample is less than the Carbon-12 sample, but the mass of both samples was the same.
d. The reactivity of the Carbon-14 sample is greater than the Carbon-12 sample, but the mass of both samples was the same.
Answer:
B.
Explanation:
Correct: b. The mass of the Carbon-14 sample is greater than the Carbon-12 sample, but the reactivity of both samples was the same .
- C-14 has two additional neutrons, so is heavier than C-12. The chemical properties will be the same, however.
double-replacement reaction.
c.
replacement reaction.
b.
decomposition reaction.
d.
combustion reaction.
The equation A + BX = AX + B represents a single-replacement or displacement reaction in Chemistry, where a more reactive element replaces another in a compound to form a new compound and releases the displaced element.
The equation A + BX = AX + B is a representation of a general single-replacement reaction, also known as a displacement reaction in Chemistry. In this type of reaction, a more reactive element (in this case represented by A) displaces or replaces another element (represented by B) in a compound, resulting in a new compound and a separate element as products. Here, A replaces B in the compound BX, leading to the formation of the new compound AX and the release of element B.

To solve this we assume that the gas is an idealgas. Then, we can use the ideal gas equation which is expressed as PV = nRT. Ata constant temperature and number of moles of the gas the product of PV isequal to some constant. At another set of condition of temperature, theconstant is still the same. Calculations are as follows:
P1V1 =P2V2
V2 = P1 x V1 / P2
V2 = 153 x 4 / 203
V2 = 3 L
