Mitosis: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Answer:
107g
Explanation:
Magnesium fluoride (MgF₂) has a molecular mass of:
Mg: 24,305 g/mol × 1 = 24,305 g/mol
F: 18,998 g/mol × 2 = 37,996 g/mol
MgF₂ = 24,305g/mol + 37,996g/mol = 62,301g/mol. That means the mass of 1,72 mol of MgF₂ is:
1,72 mol F₂ × (62,301g / 1mol) = <em>107g</em>

A) Anode - hydrogen gas
Cathode-oxygen gas
B) Hydrogen gas - The gas burns with a pop sound
Oxygen gas - The gas rekindles a glowing splint
C) The volume of gas produced at the cathode is 23
<h3>What is electrolysis?</h3>
Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.
The electrolysis of water produces two volumes of hydrogen at the anode and one volume of oxygen at the cathode.
The hydrogen gas burns with a pop sound. It is easily identified by this test. Also, oxygen is known to rekindle a glowing splint and this is a commonly used test for oxygen gas.
Since the ratio of hydrogen produced at the anode to oxygen produced at the cathode is 2:1 by volume; then when 23 of oxygen is produced at the cathode, 46 of hydrogen is produced at the anode.
