If this experiment is like the first lab, what do you think the third product being formed is that fills up the balloon?

a
A second solid neutralized compound
b
Carbon dioxide as a gas
c
Baking soda again in its reactant form

b

Carbon dioxide as a gas

If this experiment is similar to the first lab, it is likely that the third product being formed that fills up the balloon is:

b) Carbon dioxide as a gas.

This is because when an acid reacts with baking soda (sodium bicarbonate), one of the products formed is carbon dioxide gas. The reaction can be represented by the following equation:

acid + baking soda β†’ carbon dioxide + water + salt

Since the balloon is filling up, it suggests that a gas is being produced, and carbon dioxide is a common gas produced in chemical reactions involving baking soda.

To determine what the third product being formed is that fills up the balloon, we can look at the options provided: a) a second solid neutralized compound, b) carbon dioxide as a gas, or c) baking soda again in its reactant form.

If this experiment is similar to the first lab, we can make an educated guess by considering the behavior of baking soda and vinegar, which are commonly used in experiments like these.

In the first lab, when baking soda (sodium bicarbonate) reacts with vinegar (acetic acid), it produces carbon dioxide gas (CO2) as one of the products. The reaction can be represented as:

NaHCO3 + CH3COOH β†’ CH3COONa + H2O + CO2

Based on this, we can conclude that the third product filling up the balloon is most likely carbon dioxide as a gas (option b). This is because when the baking soda reacts with an acid (in this case, vinegar), it commonly produces carbon dioxide gas, which is what fills up the balloon.

Therefore, the correct answer is b) carbon dioxide as a gas.
