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.
vinegar and baking soda react to form a new gaseous substance.
b.
vinegar boils when it comes in contact with baking soda.
c.
baking soda and vinegar make a uniform mixture.
d.
baking soda has a lower density than vinegar.

The correct answer is option A.

Explanation;

In a model of volcanic eruption, baking soda and vinegar is used to demonstrate the eruption of lava from the volcano.The bubbles generated when they are mixed together is due to chemical reaction in between the acetic acid and baking soda which leads to formation of new substance(s).

The gas released is carbon-dioxide gas.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
