Answer:

HCOOH(aq) + OH-(aq) —> HCOO-(aq) + H2O(l)

Explanation:

HCOOH is a weak acid and so will not ionised completely in solution.

KOH is a strong base and will ionised completely as shown below

KOH(aq) –> K+(aq) + OH-(aq)

The overall reaction can be written as follow:

HCOOH(aq) + K+(aq) + OH-(aq) —> HCOO-(aq) + K+(aq) + H2O(l)

Cancel out the K+ to obtain the net ionic equation as shown below

HCOOH(aq) + OH-(aq) —> HCOO-(aq) + H2O(l)

A laser emits a green light with wavelength of 515 nm. Calculate the frequency of this light.
pentagon [3]

Answer:

Frequency=5.83\times 10^{14}\ Hz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength

c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 515 nm

Also, 1 m = 10^{-9} nm

So,  

Wavelength = 515\times 10^{-9} m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{515\times 10^{-9}}\ Hz

Frequency=5.83\times 10^{14}\ Hz
