Paleolithic Era
During the Paleolithic Era, early humans used mostly stone tools but at times also used wood or bone tools.
Answer:
5.5 moles of given substance.
Explanation:
The given problem can be solved by using the Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
Solution:
3.311 ×10²⁵ / 6.022 × 10²³ = moles
5.5 moles of given substance.
Answer:
I believe that it would be the third option down.
Explanation:
The thermal energy is in constant motion in the COOLER room, and when the desired temperature in the room is reached, it stops.
D all of these I’m about 99% sure
