Answer:
Answer is below with the steps in order
Explanation:
4) Blood picks up carbon dioxide from the body
7) Heart pumps carbon dioxide rich blood to the lungs
8) Inhale
9) Nose traps germs in air
10) Air moves down the trachea
3) Air moves through bronchi into the bronchioles
6) Alveoli receive oxygen pass to blood
9) Oxygen passes into the blood
11) Alveoli receives carbon dioxide from the blood
12) Oxygen-rcih blood flows to the heart
3) Carbon Dioxide moves from bonchioles to bronchi
13)Carbon dioxide flows up
1) Heart pumps oxygen-rich blood to the body
The last <em>four of five</em> steps could be switched up a little bit since it all happens synchronously, but this is the most accurate interpretation.

Explanation:
The molecules of hydrogen gas that are formed is when 48.7 g of sodium are added to water is 6.375 x 10²³ molecules
<u><em>calculation</em></u>
2 Na +2H₂O → 2 NaOH +H₂
Step 1: find the moles of sodium (Na)
moles =mass÷ molar mass
from periodic table the molar mass of Na = 23 g/mol
moles= 48.7 g÷ 23 g/mol =2.117 moles
Step 2:use the mole ratio to determine the moles of H₂
from given equation Na:H₂ is 2:1
therefore the moles of H₂ = 2.117 moles x 1/2=1.059 moles
Step 3: find the molecules of H₂ using the Avogadro's law
According to Avogadro's law 1 mole = 6.02 x 10²³ molecules
1.059 moles = ? molecules
by cross multiplication
= [(1.059 moles x 6.02 x10²³ molecules) / 1 mole] =6.375 x 10²³ molecules
