It is A. This is because the rate of reaction is defined as the speed at which the reactants are converted into the products.
Explanation:
firstly find for the molar mass of kcl and molar mass of k
and then
molar mass of k = x
molar mass of kcl= 40
cross mutiply and then simplify you will get your answer
Answer:
Wavelength,
Explanation:
Given that,
Frequency,
We need to find the wavelength of a photon of light. The relation between frequency and wavelength is as follows :
So, the wavelength of the light is .
