Answer:
When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
Explanation:
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
Answer
2.0 x 10²³ molecules.
Explanation
Given:
The number of moles of theobromide measured out = 0.333 moles.
MM of theobromide = 180.8 g/mol
What to find:
The number of molecules of theobromide the student measured.
To go from moles to molecules, multiply the number of moles by Avogadro's number.
The Avogadro's number = 6.02 x 10²³
1 mole of theobromide contains 6.02 x 10²³ molecules.
So, 0.333 moles of theobromide measured out will have (0.333 x 6.02 x 10²³) = 2.0 x 10²³ molecules.
Answer:
Outside air
Nose
Lungs
Bloodstream
Cell
Explanation:
We breathe in oxygen from the outside air in through our nose and it travels to our lungs. Inside our lungs, we have Avioli's that diffuse oxygen into our bloodstream and the bloodstream helps the oxygen travel into our cells.
Hope this helps :)
CO2 and H2O are compounds hope this helped :)
