Can someone help me with this science experiment? I don’t have the ingredients or time to do it. If you can’t that’s okay. This is plato btw, giving 50 points
Changing Ratios of Reactants
You will need these materials:
- safety goggles
- baking soda
- white vinegar at room temperature
- set of measuring spoons
- 1 cup of graduated measuring cup
- 3 or more large containers of similar size and shape; must hold at least 2 cups
- tray, rimmed cookie sheet, or large sink to hold containers and contain overflow
- paper towels
Question 1 Planning and Data Collection Part A
This investigation is a controlled experiment, so you can change only one variable at a time. Decide whether you’ll change the amount of baking soda or the amount of vinegar. Give a reason for your choice.
Part B
Now decide how many different combinations of baking soda and vinegar you will try. The number of combinations must be three or more.
Part C
List the amounts of baking soda and vinegar that you will use in each combination. Remember, the amount of one of the two substances must be held constant.
Part D
Carry out the investigation you planned. Record your data in the table. In the observation column, record the amount of bubbles you see.
Question 2 Part A
Explain whether changing the ratio of baking soda and vinegar changes the amount of carbon dioxide produced. Include the evidence you used to reach your conclusion.
Part B
In a chemical reaction, substances react in a specific ratio. Chemical reactions are used to make many products including food. For a company that carries out a chemical reaction to make a product, why would it be important to know the ratio of substances?
