A Haversian canal is referred to as any minute tube, which
forms a network in a bone and also contains blood vessels. Blood vessels, nerve
fibers and lymphatics may pass through the Haversian canal. Haversian canals are
found surrounding blood vessels and nerve cells all over the bones and interacts
with bone cells from end to end networks known as canaliculi.
Your answer is mass and speed! Please give me brainlist :)
Answer:
the mass required to inflate a 72 L bag is 191.491 g
Explanation:
reaction:
conditions:
- V = 72.0 L
- STP: P = 1 atm ∧ T = 298 K
gas law:
- PV = RTn
- R = 0.082 atm * L / K * mol
⇒ n = PV / RT
⇒ n = ((1 atm) * ( 72.0 L)) / (0.082 atm*L / K*mol) * (298 K)
⇒ n = 2.946 mol
⇒ m = n * Mw = ( 2.946 mol ) * ( 64.99 g/mol)
⇒ m = 191.491 g
He proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another.
