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.
The number of moles of sodium dichromate from the number of moles of oxygen atoms can be determined through stoichiometry. Using the molecular formula of the compound, Na2Cr2O7, 1 mole of the compound contains 7 moles of oxygen. Hence, 14 moles O2*(1 mole Na2Cr2O7/ 7 mole O2) is equal to 2 moles <span>Na2Cr2O7.</span>
Answer:
Nitrogen and Oxygen make up 99% of the Earths atmosphere. Then Argon makes up the rest of the atmosphere.
Answer:
4.7 g. Option 5 is the right one.
Explanation:
4Al(s) + 3O₂ (g) ⇄ 2Al₂O₃ (s)
We convert the mass of reactants to moles, in order to determine the limiting.
2.5 g Al / 26.98 g/mol → 0.092 moles of Al
2.5 g O₂ / 32g/mol → 0.078 moles of O₂
Ratio is 4:3. 4 moles of Al react with 3 moles of O₂
Then, 0.092 moles of O₂ would react with (0.092 . 3)/ 4 = 0.069 moles O₂
We have 0.078 moles of O₂ and we need 0.069 moles, the oxygen is the limiting in excess. Therefore the Al is the limiting reactant.
Ratio is 4:2. 4 moles of Al, can produce 2 moles of Al₂O₃
Then, 0.092 moles of Al would produce (0.092 .2) / 4 = 0.046 moles
If we convert the moles to mass, we find the anwer:
0.046 mol . 101.96 g/mol = 4.69 g
Answer:
2.2 meters
Explanation:
22 meters/ 10 minute = 2.2 mpm
