12➡6➡3➡1.5
① ② ③
3 half life = 252
half life = 84days
C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)
molar ratio of H2O to O = 6:8
<span>we have 0.200 moles of H2O so we need 0.200 * 8/6 moles of O2 = 0.267 moles of O2
Therefore, there will be 0.267 moles of O2 gas required to yield 0.2 moles of H20.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer:
1. An encounter with the barrier
2. The distance traveled by the washer.
Explanation:
Data:
z (atomic number)
p (protons)
e (electrons)
A (mass number)
<span>We know that: </span>Z = p = e
Therefore:
Z = 12
P = 12 ← protons
