Answer:
Salt is a mineral/substance that is made up of sodium chloride. It is typically used as a food ingredient and a nutrient. There are different types of salt such as kosher salt, table salt, sea salt, smoked salt, etc.
Answer:
Here's what I get
Explanation:
A condensation reaction joins two larger molecules by splitting out a smaller molecule — usually water or ammonia — between them.
In an esterification reaction, an OH from the acid and an H from the alcohol form a molecule of water.
The larger parts join to form the ester.
Ethanol and butanoic acid react to form ethyl butanoate.

D. procedure with controlled conditions and test and outcome variables
Answer: Magnesium hydroxide, Mg(OH)2
Explanation:
2HC2H3O2(aq) + Mg(OH)2(aq) → Mg(C2H2O2)2(aq) + 2H2O(l)
Acid + base → Salt + Water.
The equation above is an example of an acid-base reaction where the acid, aqeous 2HC2H3O2 reacts completely with an appropriate amount of the base, aqueous Mg(OH)2 to produce salt, aqueous Mg(C2H2O2)2 and water, liquid H2O only.
This acid-base reaction is also known as neutralization reaction.
Number of moles of FeCl2 used = mass/ molar mass
Number of moles = 507/126.751 = 4.
If one mole of Fe reacts with two moles of sodium
Then 4 moles of Fe produces 8 moles of sodium.
Number of moles of sodium = mass/molar mass
Molar mass of sodium chloride = 23 +35.5 = 58.5 g/mol
Hence mass = 8 * 58.5 = 468 g. Hence Option A.
