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?

Many bird species build nests in which they raise their offspring. one of these species is known as the magnolia warbler. breeding pairs of magnolia warblers build nests out of pieces of grass and twigs. the female warbler will then lay her eggs in the nest and sit on the eggs for a few weeks until they hatch. after the offspring have hatched, the female will continue to sit on the newborn chicks to keep them warm. both the male and the female bring food for the offspring to eat until the young are mature enough to find food on their own. which of these most likely describes why birds such as the magnolia warbler build nests in which to raise their offspring? a. nest building decreases the amount of energy used by the parent birds to raise their offspring to adulthood. b. nest building increases the probability that the offspring will survive and eventually produce offspring of their own. c. nest building decreases the amount of food that the offspring require the adult birds to provide. d. nest building increases the probability of the offspring being located by airborne predators.
