How many atoms of carbon are represented in 3CH3CH2O?<br><br> 2<br><br> 4<br><br> 6<br><br> 8
GenaCL600 [577]

Answer: 6



Explanation:


1) The structure shown is:


3CH₃CH₂O


2) The molecule is CH₃CH₂O. The chemical formula is CH₃CH₂O. The subscripts indicate the number of atoms of the corresponding atom in each molecule.


Then, there are 1 + 1 = 2 atoms of C, 3+ 2 = 5 atoms of H, and 1 atom of O.


3) The number in front of the molecule is the coefficient. It is 3, and it tells the number of molecules.


So, there are 3 molecules, which means that you have 3 times a many atoms as calculated previously.


That is 3×2 = 6 atoms of C, 3 × 5 = 15 atoms of H, and 3 × 1 = 3 atoms of O.


Then, the number of atoms of carbon (C) in 3 molecules is 6

Give an example of how you could test Charles Law?
Assoli18 [71]

Explanation:

The experiment is performed at a constant atmospheric pressure. The experiment proceeds by placing an empty flask in a boiling water bath. As the temperature increases, the air inside the flask expands. Afterwards, the gas is cooled in a water bath by maintaining the amount of the air in the flask constant.
