Answer:
Gas exchange occurs in microscopic dead-end air-filled sacs called alveoli, where a very thin membrane (called the blood-air barrier) separates the blood in the alveolar capillaries (in the walls of the alveoli) from the alveolar air in the sacs.
Explanation:
Answer:
erythrocytes, leukocytes, platelets
You mix 35mL of 0.54M NaI with 14mL of 0.84M Pb(NO3)2.
Glucose and oxygen are changed into energy and carbon dioxide during cellular respiration and that’s how carbon dioxide is released in the air.
Answer : The mass of calcium chloride is, 116.84 grams
Solution : Given,
Molar mass of calcium chloride, = 110.98 g/mole
Number of molecules of calcium chloride =
As we know that,
1 mole of calcium chloride contains molecules of calcium chloride
or,
1 mole of calcium chloride contains 110.98 grams of calcium chloride
Or, we can say that
As, molecules of calcium chloride present in 110.98 grams of calcium chloride
So, molecules of calcium chloride present in of calcium chloride
Therefore, the mass of calcium chloride is, 116.84 grams
