Parts of respiratory system:
Nose and Nasal Cavity, mouth, Pharynx, Larynx, Trachea, Bronchi and Bronchioles, Lungs and Muscles of Respiration.
Respiratory system function:
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.
Alveoli:
Alveoli are tiny sacs of air in your lungs that take up the oxygen you breathe and keep it going. The alveoli ventilate, diffuse and peruse in your lungs.
1- global patterns of wind
2- warm air rises causing most warm air to go to the equator
Answer:
136.5886g of NH3
Explanation:
N2 + 3H2 = 2NH3
The mass of the N2 = 4.01
3H2 has a 2/1 ratio
This means the mass of 3H2 is twice as much as N2.
NH3= 2*N2 = 2*4.01 = 8.02 of NH3
Then, by multiplying the mass by MX (17.031)
8.02*17.031=136.5886g can be produced. Round it if needed.
Reaction equation:
Zn + 2HCl → ZnCl₂ + H₂
One mole of gas occupies 22.4 L at STP
Moles of H₂ = 112/22.4
= 5 moles
The theoretical amount of Zn needed is 5 mol
The actual amount = 5/0.85
= 5.88 moles
mass = moles x Mr
mass = 5.88 x 65
mass = 382.2 g
The answer is D.
