The number of moles of hydrogen atoms in one mole of (NH₄)PMo₁₂O₄₀ is 4. Hence, option A is correct.

<h3>What are moles?</h3>

Moles can be given as the mass of the compound to the molar mass.

Moles = Mass/Molar mass

The subscript to the H in the formula describes the number of hydrogen atom in a molecule.

Thus, 1 molecule of (NH₄)PMo₁₂O₄₀ contains 4 atoms of hydrogen.

1 mole = 6.023*10²³ molecules

1 molecule (NH₄)PMo₁₂O₄₀ = 4 hydrogen atoms

1 mole (NH₄)PMo₁₂O₄₀ = 6.023*10²³ * 4 hydrogen atoms

1 mole (NH₄)PMo₁₂O₄₀ = 4 moles of hydrogen atoms

Thus, the moles of hydrogen atoms present in 1 mole of (NH₄)PMo₁₂O₄₀ is 4. Hence option A is correct.

Since all atoms have negatively charged electrons, shouldn’t every sample of matter have a negative charge ? Explain

Salsk061 [2.6K]

The three sub-atomic particles that made up an atom are electron, proton and neutron. The proton and neutron are present in the nucleus of an atom whereas electrons revolve around the nucleus in the orbits. The atoms are electrically neutral that is they have no charge due to the presence of equal number of protons (which is positively charged) and electrons (which is negatively charged).

All the atoms have negatively charged electrons which are counter balanced by the presence of equal number of protons in the nucleus of an atom and thus, the element is neutral in nature and possess no charge.

The process where bacteria takes nitrogen out of the air and makes it usable for other organisms is called

Likurg_2 [28]

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.

The law of conservation of energy states that energy can neither be created nor destroyed. What does “conservation” mean in this

maxonik [38]

Answer:

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
