Salt is usually formed during neutralization reactions,
that is the reaction of an acid and a base. This is illustrated as follows:
<span>HX + YOH --> XY
+ H2O</span>
where XY is the salt
From the given choices, the only pair of acid and base is:
<span>Vinegar and antacids</span>
Heat given off by burning coal is Potential Energy and Laser Light is Kinetic Energy.
The valence electrons of an element is usually determined by its atomic number. The valence elctrons are the electrons that have the highest energy level.
Fluorine has 7 valence electrons in the ground state.
