The ratio of phosphorous to oxygen is 2:5
<u>Explanation</u>:
- In a compound P2O5, the ratio of phosphorous to oxygen atoms is 2:5. Because there are two phosphorous atoms and five oxygen atoms. Both combined are called a P2O5.
- The elements of phosphorous and oxygen are added to P2O5. So P2O5 is called as phosphorous pentoxide. The element phosphorous will be added to oxygen and it will form a chemical reaction.
- This includes a change in the energy of P2O5. So the new energy will be produced.
Answer:
4.44 dm³ of SO₂
Solution:
The balance chemical equation is as follow,
CS₂ + 3 O₂ → CO₂ + 2 SO₂
According to equation,
22.4 dm³ (1 mole) CS₂ produces = 44.8 dm³ (2 mole) of SO₂
So,
2.22 dm³ CS₂ will produce = X dm³ of SO₂
Solving for X,
X = (2.22 dm³ × 44.8 dm³) ÷ 22.4 dm³
X = 4.44 dm³ of SO₂
Answer:
Saturation.
Explanation:
Hello,
In this case, the statement is accounting for the saturation vapor pressure as it is the pressure of a vapor which is in equilibrium with its liquid, in other words it is the maximum exerted pressure possible by the vapor at a given temperature or just the maximum amount of the vapor, so there is neither no more vapor that could condense nor more liquid that could boil.
