I would say developed technologies which somehow were lost

like the stone age: the stone hammer, who used that afterwards in the roman empire era and stuff?

Answer:

The correct answer will be options-

1. had understanding of scientific principles.

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.

Thus, the selected options are the correct answer.

A 1.00 L of a solution is prepared by dissolving 125.6 g of NaF in it. What would be the molarity of this solution?
DedPeter [7]

Answer:

2.99 M

Explanation:

In order to solve this problem we need to keep in mind the definition of molarity:

  • Molarity = moles of solute / liters of solution

In order to calculate the moles of solute, we <u>convert 125.6 g of NaF into moles</u> using its <em>molar mass</em>:

  • 125.6 g NaF ÷ 42 g/mol = 2.99 mol NaF

As the volume is already given, we can proceed to <em>calculate the molarity</em>:

  • Molarity = 2.99 mol / 1.00 L = 2.99 M

Chemistry help please! I just need to make sure the answers correct.... Thank you!
Veronika [31]
1. At constant tempaerature and pressure, 3 tablets produce 600cm^3 of gas
Thus calculating for 1 tablet that produces 600 / 3 = 200 cm^3
So now two tablets produce 200 x 2 = 400 cm^3
2. We have the equation PV = nRT, n being the number of moles
Pressure P = 1,000 kPa
Volume V = 3 L
R = 8.31 L kPa/mol-K
Temperature T = 298 K
n = PV / RT = (1000 x 3) / (8.31 x 298) = 3000 / 2476.38 = 1.21 moles
Number of moles = 1.21 moles.
