To ensure that the 9-Fluorenone was totally dry, it had to be washed with methylene chloride. To make sure that methylene chloride is present in a pure solution, sodium sulfate binds to water and precipitates.
<h3>
What is the purpose of the sodium sulfate?</h3>
- Although it has numerous additional uses, sodium sulfate is primarily employed in the production of detergents and in the Kraft process of paper pulping.
- The decahydrate's natural mineral form, mirabilite, accounts for about half of the world's output, with the other half coming from chemical byproducts. Sodium sulfate was used as a drying, isolating, and anhydrous salt for the 9-fluorenone.
- To make sure that methylene chloride is present in a pure solution, sodium sulfate binds to water and precipitates.
- The sodium salt of sulfuric acid is known as sodium sulfate. Na2SO4 is the chemical formula for sodium sulfate. The mineral thenardite, which is also known as anhydrous sulfate, is described as a white, crystalline solid, whereas the decahydrate Na2SO4. 10H2O is also known as Glauber's salt or the mirabilis salt.

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. Some points will be nice
Answer:
Mg₃N₂ (magnesium nitride)
Explanation:
M(total) = M(mg) + M (n)
M (n) = M(total) - M(mg)
= 0.433g - 0.313g
= 0.12g
mole (N) = 0.12g / 14.0067 g/mol
= 0.008567
mole Mg = 0.313g / 24.3050 g/mol
= 0.012878
Mg = 0.012878 / 0.008567
= 1.5
N = 0.008567 / 0.008567
= 1
multiply by 2 to get whole numbers
Mg = 1.5 × 2 = 3
N = 1 × 2 = 2
Mg₃N₂ (magnesium nitride)
In an endothermic reaction, the heat in going in. it absorbs energy from its surroundings.
hope this helps!
