a new chemical substance is produced.	□	□	□
a chemical change occurs.	□	□	□
a physical change occurs.	□	□	□

check answer
remaining attempts : 3

Explanation:

To solve this, we analyze each process:

1. Popping an Inflated Balloon

• Physical change: Popping a balloon only changes its shape/state (no new substance, chemical makeup remains).
• Chemical change-related rows: No (no new substance, chemical makeup doesn’t change).

2. Dissolving Sugar in Water

• Physical change: Dissolving is a physical process (sugar molecules disperse, no new substance, chemical makeup of sugar/water remains).
• Chemical change-related rows: No (no new substance, chemical makeup doesn’t change).

3. Mixing Vinegar and Baking Soda

• Chemical makeup changes: Vinegar (acetic acid) + baking soda (sodium bicarbonate) react to form new substances (CO₂, water, sodium acetate).
• New chemical substance produced: The reaction creates CO₂, water, etc.
• Chemical change occurs: Reaction = chemical change (new substance formed).
• Physical change: No (this is a chemical reaction).

Filling the Table:

Process	Chemical makeup changes	New substance produced	Chemical change occurs	Physical change occurs
Dissolving Sugar in Water	❌	❌	❌	✅
Mixing Vinegar and Baking Soda	✅	✅	✅	❌

(Mark the checkboxes as per the above: Pop Balloon → Physical; Dissolve Sugar → Physical; Vinegar+Baking Soda → Chemical makeup, New substance, Chemical change.)
