Dalton and Marcy were conducting an experiment at school during the experiment. They added a little dry yeast to some hydrogen peroxide the combination began to bubble rapidly, and the container felt warm. They captured some of the gas that was formed, and they discovered that the gas they captured, had a new property when they put a lit match into the gas and it made the lit, match glow much brighter. Dalton and Marcy determined that all.——-must have taken place. When this kind of changes take place atoms must ——?
Based on the given information, Dalton and Marcy observed that the addition of dry yeast to hydrogen peroxide caused the combination to bubble rapidly and the container to feel warm. They also captured the gas produced during the reaction and found that when they put a lit match into the gas, the match glowed much brighter. From these observations, we can determine that a chemical reaction took place.
During a chemical reaction, atoms must undergo rearrangement. This means that the atoms in the reactants (in this case, dry yeast and hydrogen peroxide) are rearranged to form new products, in this case, gas and other substances.
Based on the information provided, Dalton and Marcy observed the following events during their experiment:
1. When they added dry yeast to hydrogen peroxide, the combination started to bubble rapidly.
2. The container felt warm, indicating the release of energy during the reaction.
3. They captured some of the gas produced during the reaction.
4. When they put a lit match into the captured gas, the match glowed much brighter.
From these observations, Dalton and Marcy concluded that a chemical reaction, specifically a decomposition reaction, took place. Decomposition reactions involve the breakage of a compound into simpler substances.
To answer the question about what happens to atoms during this kind of change, it is important to understand the Law of Conservation of Mass. According to this law, the total mass of the reactants before a chemical reaction is equal to the total mass of the products after the reaction. This means that atoms are neither created nor destroyed during a chemical reaction, but they are rearranged to form new substances.
In the case of the experiment, the decomposition reaction likely produced new substances and rearranged the atoms of the reactants. The gas formed (possibly oxygen or another gaseous compound) had the ability to support combustion more efficiently, which caused the lit match to glow brighter.
In summary, during a chemical reaction like the one observed by Dalton and Marcy, atoms do not disappear or appear out of nowhere. They are rearranged to form new substances as governed by the Law of Conservation of Mass.
