Answer:
For the first question, to determine the total number of molecules of nitrogen dioxide, first make use of the molar mass of the nonpolar compound and then use that to find the total number of moles and then subsequently after make use of the ratio for the Avogadro's number to determine the total number of molecules of this compound.
For the final question, do the inverse, where we make use of the molecules of the compound and then use Avogadro's number to determine the moles of the compound and then use the same molar mass of the compound to determine the grams of the Nitrogen Dioxide.
Answer: O 10.1 is your answer! Please mark me as brainlyest!?
True. A mole is a standard unit of measurement. It's like that riddle; "What's heavier, a pound of bricks or a pound of feathers? Neither- a pound is a pound no matter what it's made of."
Answer:
C) 2CO + O₂ → 2CO₂
Explanation:
The equation C is correct.
2CO + O₂ → 2CO₂
This equation have four oxygen atom and two carbon atoms on both side of equation. So it is correctly balanced.
All others are incorrect:
A) CO + O₂ → CO₂
this is incorrect because there are three oxygen atoms on left while two atoms on right.
B) CO + 2O₂ → 2CO₂
this is incorrect because there are five oxygen atoms on left while four atoms on right.
D) 2CO + 2O₂ → 2CO₂
this is incorrect because there are six oxygen atoms on left while four atoms on right.
