2. had understanding of scientific principles.

3. developed technologies which somehow were lost.

Explanation:

The ancient people are considered primitive in the sense that they lived during the time when they started understanding the world to exploit it. Scientifically they were all considered modern humans as they possessed the brain with the same capacity as we have that is 1500 cc.

The collected evidence show that they formed the earlier civilizations on earth and were aware of their natural world in which they were living and tried to understand the world so they can exploit nature.

The developed the scientific principles, developed the language of mathematics for business and the better economy as well as tools and techniques which helped their survival which was lost.

How many milligrams of product can be produced from the complete Diels-Alder reaction of 180. mg of anthracene and 100. mg of ma
ZanzabumX [31]

Answer: It will be produced 276,3 mg of product

Explanation: The reaction of anthracene (C14H10) and maleic anhydride (C4H2O3) produce a compound named 9,10-dihydroanthracene-9,10-α,β-succinic anhydride (C18H12O3), as described below:

C14H10 + C4H2O3 → C18H12O3

The reaction is already balanced, which means to produce 1 mol of C18H12O3 is necessary 1 mol of anthracene and 1 mol of maleic anhydride.

1 mol of C14H10 equals 178,23 g. As it is used 180 mg of that reagent, we have 0,001 mol of anthracene. With it, the reaction produces 0,001 mol of C18H12O3.

As 1 mol of C18H12O3 equals 276,3 g, the mass produced is 276,3 mg.
