False, divergent boundaries are when two plates move away from each other.
Answer:
1. 0.45 mole
2. 49.95g
Explanation:
The following were obtained from the question:
Volume of solution = 300mL = 300/1000 = 0.3L
Molarity = 1.5 M
Mole of CaCl2 =?
1. We can obtain the mole of the solute as follow:
Molarity = mole of solute /Volume of solution
1.5 = mole of solute/0.3
Mole of solute = 1.5 x 0.3
Mole of solute = 0.45 mole
2. The grams in 0.45 mole of CaCl2 can be obtained as follow:
Molar Mass of CaCl2 = 40 + (35.5 x 2) = 40 + 71 = 111g/mol
Mole of CaCl2 = 0.45 mole
Mass of CaCl2 =?
Mass = number of mole x molar Mass
Mass of CaCl2 = 0.45 x 111
Mass of CaCl2 = 49.95g
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.
