Answer:
xenon
Explanation:
Xenon is a non-metal, odorless gas, consist of single atoms, colorless, and 8 valence electrons out of everything else on this list.
You could mix it with some vinegar, if it has cornstarch or baking soda in it will bubble, I'm not sure how to tell with baking powder... I'm not sure if it would have a reaction or not.
Hope this helps.
I’m working on this rn lol
According to the Law of Definite Proportions from Dalton's Atomic Theory, each compound is composed of a fixed ratio of each of its individual elements. So, the number of individual elements per 1 particle of that compound is represented by the subscripts. The answers are as follows:
Table sugar: 12 atoms of carbon, 22 atoms of hydrogen; 11 atoms of oxygen; 45 total atoms
Marble: 1 atom of calcium, 1 atom of carbon; 3 atoms of oxygen; 5 total atoms
Natural gas: 1 atom of carbon, 4 atoms of hydrogen; 5 total atoms
Rubbing alcohol: 3 atoms of carbon, 8 atoms of hydrogen; 1 atom of oxygen; 12 total atoms
Table sugar: 1 atom of silicon; 2 atoms of oxygen; 3 total atoms
