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.
Answer:
Double replacement is the answer
<span>The
density of an object is defined to be its mass divided by the volume it
occupies. For this problem, the mass of the cube was given to be 25 g while its
volume is 125 cm</span>³. Thus, we simply divide 25 g by 125 cm³ to get the object’s density. We then calculate that the cube has a density of
0.2 g/ cm³.
From the ideal gas law
pv=nRT , n is therefore PV/RT
R is the
R is gas constant =62.364 torr/mol/k
P=500torr
V=4.00l
T=500+273=773k
n={(500 torr x 4.00l)/(62.364 x773k)}=0.041moles
the number of molecules=moles x avorgadro costant that is 6.022x10^23)
6.022 x 10^23) x0.041=2.469 x10^22molecules
