The atomic or ionic mass of sodium is 22.99, and the atomic or ionic mass of chlorine is 35.45. A formula unit of sodium chloride contain one ion of each. Therefore, the mass ratio between sodium and chlorine in sodium chloride is 0.649. The mass ratio between 46 and 70 is 0.657. Therefore, chloride is the limiting reactant in this pair. The mass ratio of chloride to sodium chloride is 35.54/(22.99 + 35.54) or 0.607. Therefore, the mass of sodium chloride formed will be 70/(0.607) or 115 gm, where the depressed last digit indicates that it may not be accurate to + 1. (The limiting datum, 70, has only two significant digits.)
To prevent the magnesium or sodium reacting with oxygen in the air
sodium chloride is an ionic compound. it has reacted so it's not a mixture. It is a ionic compound because Na is a metal and Cl is a non-metal
The limiting reagent is sodium hydroxide.
yes
No. Table salt is sodium chloride. Sodium on its own is a completely different substance that bursts into flame on contact with water.
Sodium chloride is an ionically bonded compound formed by the reaction of sodium and chlorine atoms. In the compound, each sodium atom that reacted becomes a positively charged sodium cation and each chlorine atoms that reacted becomes a negatively charged chloride anion.
hydrochloric acid and sodium hydroxide
To prevent the magnesium or sodium reacting with oxygen in the air
Sodium chloride is an electrolyte only in solution or as melted, when is completely dissociated in ions.

NaCl (s) + H2SO4 (l)-------> HCl (g) + NaHSO4 (s)
yes
Table salt is NaCl (Sodium Chloride), but a salt in chemistry is just the solid produced when a metal is reacted with an acid.
.033 mol H2
No. Table salt is sodium chloride. Sodium on its own is a completely different substance that bursts into flame on contact with water.
sodium chloride helps to decrease the solubility of an organic compound therefore its easier to extract an organic compound almost completely from water
