It might be double displacement which means that the anions and cations of two different molecules switch places, forming two entirely different compounds.

Answer: double displacement reaction

Explanation:

A double displacement reaction is one in which exchange of ions take place.

The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

Example: CuS(aq)+AgNO_3(aq)\rightarrow Ag_2S(aq)+Cu(NO_3)_2(aq)

As can be seen in the chemical reaction, cations are replaced by cations and anions are replaced by anions.

Thus a reaction in which two ions switch places is double displacement reaction.

What is the mass ratio of aluminum to oxygen in aluminum oxide, Al2O3?
liubo4ka [24]

Answer:

9 : 8

Explanation:

Aluminum oxide has the following formula Al₂O₃.

Next, we shall determine the mass of Al and O₂ in Al₂O₃. This can be obtained as follow:

Mass of Al in Al₂O₃ = 2 × 27 = 54 g

Mass of O₂ in Al₂O₃ = 3 × 16 = 48 g

Finally, we shall determine the mass ratio of Al and O₂. This can be obtained as follow:

Mass of Al = 54 g

Mass of O₂ = 48 g

Mass of Al : Mass of O₂ = 54 : 48

Mass of Al : Mass of O₂ = 54 / 48

Mass of Al : Mass of O₂ = 9 / 8

Mass of Al : Mass of O₂ = 9 : 8

Therefore, the mass ratio of Al and O₂ in Al₂O₃ is 9 : 8

How many moles of hydrogen atoms are there in one mole of (NH4)PMo12O40?
ValentinkaMS [17]

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.
