A certain shade of blue has a frequency of 7.08×1014 Hz. What is the energy of exactly one photon of this light? Planck's consta
Anvisha [2.4K]

Answer:

We have the final answer as

4.69 \times  {10}^{ - 19}  \:  \:  J

Explanation:

To find the energy of a photon of this light we use the formula

<h3>E = hf</h3>

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

f = 7.08×10¹⁴ Hz

We have

E = 7.08×10¹⁴ × 6.626 × 10-³⁴

We have the final answer as

4.69 \times  {10}^{ - 19}  \:  \:  J

Hope this helps you

Predict the products of the electrolysis of molten nickel(II) iodide. Write an ionic half-equation for the formation of one of t
Daniel [21]

Answer:

See explanation

Explanation:

The electrolysis of  nickel(II) iodide yields nickel solid and iodine gas.

In the oxidation half equation;

2I^-(aq)-------> I2(g) + 2e

In the reduction half equation;

Ni^2+(aq) + 2e  -----> Ni(s)

These are the half equations of the process;

The  overall equation is;

Ni^2+(aq) + 2I^-(aq)-------> NiI2
