Helium is a light gas. Movement can be predicted by which chamber has the lighter gas(es) and which chamber has the heavier. constant changes can also be a variable. If the gas is constant, then changes are more easily predicted.
Make sure that there an exit and no over head power lines and wate for a backup
Answer : The mass of oxygen combined with 1.00 g of carbon in carbon dioxide will be, 2.66 grams.
Explanation :
Law of multiple proportion : It states that when two elements can combine to form two or more different compounds then the mass of one element compared to fixed mass of the other will always be in a ratio of small whole numbers.
As we are given that the mass of ratio of carbon and oxygen in CO is 1 gram and 1.33 gram.
Ratio of C and O in CO = 1 : 1
Ratio of C and O in CO₂ = 1 : 2
So, the mass of ratio of carbon and oxygen in CO₂ will be 1 gram and (2×1.33) 2.66 gram.
Thus, the mass of oxygen combined with 1.00 g of carbon in carbon dioxide will be, 2.66 grams.
