Baking soda and vinegar can be used to model a volcanic eruption in a science demonstration because they bubble violently when mixed. What can be concluded about mixing vinegar and baking soda? A.
Baking soda has a lower density than vinegar.
B.
Baking soda and vinegar make a uniform mixture.
C.
Vinegar boils when it comes in contact with baking soda.
D.
Vinegar and baking soda react to form a new gaseous substance.

D.Vinegar and baking soda react to form a new gaseous substance

When Vinegar and baking soda react, it produces carbon dioxide which bubbles (effervescence) as it is produced. This is why this reaction is often used to mimic that of a volcanic eruption.

C₂H₄O₂ +           NaHCO₃           →     NaC₂H₃O₂       +     H₂O  +  CO₂

vinegar + sodium bicarbonate  →   sodium acetate +    water +  carbon                                                      

                                                                                                            dioxide

the atomic mass is the bottom number on the element.
