A sealed plastic bag filled with vinegar is about to mix with baking soda. When the baking soda mixes with the vinegar, bubbles will form and the plastic bag will start to expand. Why does the bag expand? (select the best answer)

The gas particles from the reaction will make the bag expand by pushing out

If you double the baking soda added to the vinegar in the bag, describe how that would change your model from Question 5

The extra baking soda will make a larger reaction creating more gas that will likely make the bag burst.

More baking soda will make less reaction

Emi drops a cup of baking soda into a glass container that has vinegar at the bottom of it. Then, she quickly puts a balloon on top of the container. What do you predict will happen to the balloon?

The balloon will get bigger because it will become filled with gas particles that are too small to be seen.

The balloon will get bigger because it will become filled with solid (baking soda) particles that are too small to be seen.

The balloon will get bigger because it will become filled with liquid (vinegar) particles that are too small to be seen.

The balloon will stay the same because it will not become filled with anything.

Priya needs some baking soda to bake a cake. She has three white powders (salt, baking soda , and baking powder ) in her kitchen, but they don’t have labels. She knows that baking soda will bubble and fizz if mixed with vinegar, but not with water. Baking powder will bubble and fizz if mixed with vinegar. It also bubbles when mixed with water. Salt does not bubble with vinegar or water. Priya conducts the above two experiments in her kitchen. Which of the three powders (Powder A, Powder B, or Powder C) do you think is the baking soda ? Why do you think that? Support your answer with evidence from the experiments.

Either A or B is the baking soda. C must be the salt.

Either B or C is the baking soda. A must be the salt.

Either A or C is the baking soda. B must be the salt.

Priya can’t figure anything out if she only looks at the Vinegar Experiment.

Which of the three powders (Powder A, Powder B, or Powder C) do you think is the baking soda ? Why do you think that? Support your answer with evidence from the experiments. (pick the BEST answer)

I think powder B is the baking soda. Both A and B reacted with vinegar, but only powder A reacted with water which makes it the baking powder because baking soda doesn't react with water.

Powder B because it created bubbles when mixed with vinegar.

Powder B because it didn't react with water.

Powder C because it didn't react with water or vinegar.

Samuel wants to make something called “elephant toothpaste.” It’s a chemical reaction that creates lots of white foam that looks like toothpaste for an elephant! Samuel knows that the reaction happens when two ingredients are mixed together. He also knows that one of the ingredients is hydrogen peroxide. Samuel doesn’t know what the other ingredient is. Using the ingredients baking powder, yeast, baking soda, and sugar, describe the steps of an experiment that Samuel could perform to figure out what he needs to make “elephant toothpaste.”

Sam should carefully set up an experiment where he does one reaction at a time and records which one or multiple make the reaction he is looking for, that way he knows which ingredients to use

Sam should mix stuff with other stuff

Sam should just start pouring Hydrogen peroxide in all the other things

he should mix all the ingredients in one big bowl and see what happens.
