Answer:
The electric field between the plates is 1875 V/m.
Explanation:
Given that,
Separated d=1.6 cm
Potential of negative plate = 0 V
Potential halfway between the plates = 15 V
We need to calculate the total potential
Using formula of potential
Put the value into the formula
We need to calculate the electric field between the plates
Using formula of electric field
Direction is negative as the field always points from positive to negative plate
Hence, The electric field between the plates is 1875 V/m.

Although your selections are indications of chemical reactions, if you are referring to only the chemical reaction that occurred in your example, then the two answers are the only choices.
A chemical reaction occurs when the reactants form a new product. Signs of a chemical reaction include change is smell, color and temperature. In some cases, precipitate forms.
Answer:
A. Ar, Si, Mg, Na
Explanation:
ar is argon which is an inert gas. its in group 18. whole column is filled with inert gases.
na is sodium. very reactive. its in group 1. whole column is filled with very reactive elements
