The answer is
Explanation:
The energy of a quantum of light can be found by using 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 = 4.31 × 10¹⁴ Hz
We have
E = 4.31 × 10¹⁴ × 6.626 × 10-³⁴
We have the final answer as

<u>Answer:</u> The speed of light in miles per minutes is
<u>Explanation:</u>
We are given the speed of light is and we need to convert it into miles/min. So, we use the converion factor:
1 hour = 60 minutes
Converting that quantity into miles/minutes, we get:
Hence, the speed of light in miles per minutes is
Answer:
Explanation:
Hello there!
In this case, according to the given information, it is possible for us to set up the following chemical equation at equilibrium:
Now, we can set up the equilibrium expression in terms of x (reaction extent) whereas the initial concentration of both iodine and bromine is 0.5mol/0.250L=2.0M:
Thus, we solve for x as show below:
Therefore, the concentrations of both bromine and iodine are:
