Answer:
It is necessary because Trans-cinnamic is a limiting reagent in the mixture reaction while Bromine is the excess reagent
Explanation:
It is necessary to maintain excess bromine in the reaction mixture because Bromine is the excess reagent in the reaction mixture and if it's quantity is less it would consume the limiting reagent ( Trans-cinnamic ) completely . hence Bromine should maintain excess quantity in the reaction mixture
X is always the independent variable
PV=nRT n=PV/RT
R=.0821 atm x L
Mol x K
T=318K
P=.55atm
V=37.4L
n= (.55atm) (37.4L) /
.0821atm x L (318k)
mol x K
n= .79 mol of sulfur dioxide
Answer:
As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption
A - 1. Carbon dioxide is converted to sugar used for food (this is process of phosynthesis).G - 2. Carbon trapped in fossil fuels is converted to carbon dioxide (this is combustion of fuel).E - 3. Organic carbon is converted to fossil fuels.H - 4. Carbon dioxide is converted to carbonates.F - 5. Sugar is broken down and converted to carbon dioxide (this is breathing).
