Percentage yield= (actual/theoretical)x100
So in this case the actual yield is 110 and the theoretical yield is 125.
So you would do =(110/125)x100
So the answer would be =88%
The correct answer is NH₄Cl.
With the increase in temperature, endothermic reactions are favored. The dissolution of NH₄Cl in water is an example of an endothermic reaction. When the temperature is increased more dissolution of the salt takes place, thus, the solubility of the salt increases.
Hence, it can be said that NH₄Cl will exhibit the greatest change in the solubility per 100 g solvent with an elevation in temperature.
Convert 0.47g 2-naphthol to mols. mol = g/molar mass.
Using the coefficients in the balanced equation, convert mols 2-naphthol to mols 2-butoxynaphthalene then you have to Convert mol 2-butoxynaphthalene to grams. g = mols x molar mass. This is the theoretical yield.
Answer:
You find a separatory funnel set up in a fume hood. There are clearly two visible layers. Describe a method you could use to determine which layer is the aqueous layer.
Explanation:
In the separating funnel, the liquid with less density exists at the top layer and the liquid with greater density will exist at the bottom layer.
To identify the aqueous layer, add a bit of water to the separating funnel.
Then, observe where the water will go and mix.
If it mixes with the bottom layer, then the bottom layer is the aqueous layer.
If water mixes with the top layer, then top layer is the aqueous layer.
