Is it possible for an electron in a hydrogen atom to emit a gamma ray by falling to a lower energylevel?

jeka94

No, its not possible. Let's go back to 4th grades' basic science.
"Energy can not be created or destroyed."
This applies to everything, even atoms!

A sample of kerosene has a mass of 36.4g. It’s volume is 45.6mL. What is the density of kerosene?

stira [4]

Answer:

<h2>Density = 0.8 g/cm³</h2>

Explanation:

The density of an object can be found using the formula

<h3> $Density(\rho) = \frac{mass}{volume}$ </h3>

From the question

mass of kerosene = 36.4 g

volume of kerosene = 45.6 mL

To find the density substitute the values into the above formula and solve

We have

<h3> $Density = \frac{36.4}{45.6}$ </h3>

= 0.7982

We have the final answer as

<h3>Density = 0.8 g/cm³</h3>

Hope this helps you
