Answer:
What was the purpose of the experiment?
Type your answer here: The purpose of the experiment was to perform and observe the results of a variety of chemical reactions. To become familiar with the observable signs of chemical reactions. To identify the products formed in chemical reactions and predict when a reaction will occur. To write balanced equations for the reactions studied.
Explanation:
sorry i can only tell you the first one
Introduction
What was the purpose of the experiment?
The purpose of this experiment is to create CO2, also known as carbon dioxide, and observe chemical reactions.
How can you identify the gas produced in a chemical reaction without observing the atoms and molecules directly? Explain.
If I look at how the gas would react or its qualities, I can identify the gas without having to observe its atoms directly.
Write a hypothesis based on observations and scientific principles.
I hypothesize that the mixture produced carbon dioxide, an acidic and colorless gas. In addition to organic materials, such as leaves and dirt, carbon dioxide is also produced when they decay.
Experimental Methods
What tools or materials did you use to collect your data?
To conduct my experiment, I used a glass cup, baking soda, vinegar, paper to record my observations, and a match.
Data and Observations
Record your observations.
The baking soda and vinegar made bubbles and some steam. When I put the match above the glass, the flame went out.
Conclusions
What conclusions can you draw about the identities of the gases produced in each chemical reaction? Write an evidence-based claim.
The chemical reaction of CO2 caused the flame to go out.
Based on your observations, which equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3)? Explain.
"C" _"2" "H" _"4" "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2
"C" _"2" "H" _"4" "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"O" _2
"C" _"2" "H" _"4" "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"H" _2
"C" _"2" "H" _"4" "O" _"2" +2"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2
The equation that best models the reaction of vinegar is A
Because "C" _"2" "H" _"4" "O" _"2" is the acid vinegar
"NaHC" "O" _"3" is the baking soda
"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2 is the product or the reaction.
