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
.
Answer:
0.045 M/s
Explanation:
Given:
Initial concentration of A = 0.625 M
Final concentration of A = 0.100 M
Total time taken for the change of concentration = 11.6 seconds
The average rate of reaction is calculated as:
= 
on substituting the respective values, we get
= 
or
The average rate of reaction = 0.045 M/s
Answer:
Explanation:(1)base are slippery to touch e.g sodium hydroxide NaOH(aq)..
(2) They can be corrosive e.g pottasium hydroxide KOH(aq) and sodium hydroxide NOH(aq)
(3) They can act as electrolytes e.g NaOH(aq)
(4) they react to acids to form salt and water
Na0H(s)+HCL(aq)>>>NaCL(a)+H20(l)
(5)they dissolve in water to form hydroxyl ion
KoH(aq) >>>>>k+ + 0H-
