The excretory system removes metabolic wastes from the body. The major organs of excretion are the kidneys, a pair of bean-shaped organs located below the liver. The kidneys filter blood and regulate water balance in the body
<u>Answer:</u> The mass of oxygen reacted is
<u>Explanation:</u>
We are given:
Moles of propane = 9.98 mol
For the given chemical equation:
By Stoichiometry of the reaction:
1 mole of propane reacts with 5 moles of oxygen.
So, 9.98 moles of propane will react with = of oxygen.
To calculate the mass of carbon dioxide, we use the equation:
Moles of oxygen = 49.9 moles
Molar mass of oxygen gas = 32 g/mol
Putting values in above equation:
Hence, the mass of oxygen reacted is
Answer:
The correct answer is Pangea.
Explanation:
Pangea, also spelled Pangaea, in early geologic time, was a supercontinent that incorporated almost all the landmasses on Earth.
