Answer:
Distillation
Explanation:
Miscible solvents are separated from each other through a process called as Distillation. This technique works on the principle of difference in the boiling point of the solvents that are forming the miscible solution.
Example:
Water and Ethanol are two miscible solvents. They have different boiling points.
Ethanol = 78.37 °C
Water = 100 °C
In a experimental setup attached below, water and ethanol mixture is taken in a round bottom flask and heated on a hotplate. Ethanol having less boiling point than water boils first and evaporates. The Ethanol vapors are condensed as they passes through the condenser. In this way the ethanol is separated first and water having greater boiling point is left behind.
The three main types of lipids are triglycerides, steroids and phospholipids
Answer:
Empirical formula will be (NH₄)₃PO₄, which matches the molecular formula
Explanation:
This is the reaction:
NH₃ + H₃PO₄ → 28.2% N, 20.8% P, 8.1% H, 42.9% O
In 100 g of compound we have:
28.2 g N
20.8 g of P
8.1 g of H
42.9 g of O
Now we divide each between the molar mass:
28.2 g / 14 g/mol = 2.01 mol
20.8 g / 30.97 g/mol = 0.671 mol
8.1 g / 1 g/mol = 8.1 mol
42.9 g / 16 g/mol = 2.68 mol
And we divide again between the lowest value of moles
2.01 mol / 0.671 mol → 3
0.671 mol / 0.671 mol → 1
8.1 mol / 0.671 mol → 12
2.68 mol / 0.671 mol → 4
Molecular formula will be: N₃PH₁₂O₄ → (NH₄)₃PO₄
Empirical formula will be (NH₄)₃PO₄, which matches the molecular formula
Answer: 88g
Explanation:
11 moles H2 = 11 mole H2O = 5.5 moles O2 = 16*5.5 g
