Answer:
The minimum thickness is
Explanation:
generally the equation for thin film interference is mathematically represented as
Where t the thickness
m is any integer
n is the refractive index of the film
is the wavelength of light
Since we are looking for the thickness we make t the subject of the formula
m= 0 cause the thickness is minimum at m=0
Substituting values
<h3>
Answer:</h3>
AgCl + NaNO₃
<h3>
Explanation:</h3>
- The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
- In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
- In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
- Therefore, the complete reaction is given by;
AgNO3 + NaCl → AgCl + NaNO₃
- But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.
