A hot filtration should be used in the process of Crystallization.
<h3>What is Crystallization?</h3>
This is the conversion of a chemical in liquid form to a crystalline solid. The crystal formed are repeating three-dimensional pattern or lattice.
Hot filtration is used in the process of Crystallization of a solid which contains impurities that are insoluble in the crystallization solvent and also to remove highly colored impurities from a solid.

Answer:
Molarity of Limonol is
M = 1.43mol/L
Explanation:
M = mols/L
mols = g/molar mass
Therefore, determine molar mass, divide into grams luminol and divide that by 75 mL (in liters) to obtain molarity = M.
Molar mass of Limonol = 177.16 g/mol
mols = 19g / 177.16 g/mol
mols = 0.1072mol
Molarity of Limonol, M = 0.1072 mol / 0.075
M = 1.43mol/L
Answer:
base
Explanation:
carbonic acid - H2CO3 - is a weak acid. Therefore, HCO3 itself is its conjugate base. The Na(sodium) ion is neutral.
This means that NaHCO3 is a base. (a weak one)
Answer:
2
Explanation:
2 balances out the equation
Answer:
The percent yield of this reaction is 84.8 % (option A is correct)
Explanation:
Step 1: Data given
The student isolated 15.6 grams of the product = the actual yield
She calculated the reaction should have produced 18.4 grams of product = the theoretical yield = 18.4 grams
Step 2: Calculate the percent yield
Percent yield = (actual yield / theoretical yield ) * 100 %
Percent yield = (15.6 grams / 18.4 grams ) * 100 %
Percent yield = 84.8 %
The percent yield of this reaction is 84.8 % (option A is correct)
