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.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
