There are many examples of chemical equilibrium all around you. One example is a bottle of fizzy cooldrink. In the bottle there is carbon dioxide (CO2) dissolved in the liquid. There is also CO2 gas in the space between the liquid and the cap
Answer:
D. 2666.67g/dm3
Explanation:
Hello,
In this case, we compute the solubility as:
Thus, we compute:
Therefore, answer is D. 2666.67g/dm3.
Best regards.
P₂O₅ is an empirical formula
<h3>Further explanation</h3>
Given
compounds
Required
an empirical formula
Solution
The empirical formula is the smallest comparison of the atoms forming the compound.
Molecular formulas are formulas that show the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
1. P₂O₅ : the ratio of compounds cannot be further reduced to whole numbers⇒empirical formula
2. P₄O₆ : molecular formula
(P₂O₃)₂=P₄O₆
P₂O₃ : empirical formula
3.C₂H₄ : molecular formula
(CH₂)₂=C₂H₄
CH₂ : empirical formula
4. C₃H₆ : molecular formula
(CH₂)₃=C₃H₆
CH₂ : empirical formula
Answer:
730×10 6 g
Explanation:
each one mole of NH4NO3 has 2 moles of nitrogen (2×14)
N NH4NO3
2×14 14+(4×1) +14+(3×16)
28 80
? 2.086 × 10 9
2.086× 10 9 ×28 ÷80 = 730 × 10 6 g of Nitrogen
