Is Nonane the correct answer? I did it based off of the molecular formula but I’m not sure if that’s the answer youre looking for
The answer is about 376.48 grams, but rounded to three significant figures, it’s 376 grams
Answer:
45 meters
Explanation:
If it takes the slug 20 minutes to travel 15 meters, you multiply the 15 by three to get the distance for 60 minutes.
Answer:
The correct answer is 3.36 L
Explanation:
The molecular weight of CO₂ is 44 g/mol (2 O + 1 C= (2 x (16 g/mol )) + 12 g/mol). We have 44 g in 1 mol CO₂, and we want to know how many mol are in 6.6 g:
44 g -------------- 1 mol CO₂
6.6 g -------------- X= 6.6 g x 1 mol / 44 g = 0.15 mol
In normal conditions of temperature and pressure, 1 mol of ideal gas occupies 22.4 L of volume, thus:
1 mol CO₂ ------------ 22.4 L
0.15 mol -------------- X= 3.36 L
So, 6.6 g CO₂ are equivalent to 0.15 mol CO₂ and they occupy 3.36 L.
Answer:
Number of iodine atoms = 2 × 4 = 8
Number of oxygen atoms = 2 × 9 = 18
Explanation:
Coefficient 2 is placed in front of the product tetraiodine nonaoxide:
= 
Number of iodine atom in a single molecule tetraiodine nonaoxide = 4
Number of oxygen atoms in a single molecule tetraiodine nonaoxide = 9
Coefficient 2 is placed in front of the product tetraiodine nonaoxide:
=
Number of iodine atoms = 2 × 4 = 8
Number of oxygen atoms = 2 × 9 = 18
