Materials: laser pointer/ flashlight with a paper with a small slit, glass prism
step 1.) turn on the laser pointer point it up to the ceiling.
step 2.) point to prism, explain how the light refracts in the prism. and how it changes.
(I hope this helps!)
Answer:
Proton = 119
Electron = 119
Neutron = 183
Explanation:
Mass number (A) = 302
Atomic number (Z) = 119
Proton = atomic number = 119
Since there is no charge on the element, it means the element is neutral.
Therefore,
Electron = proton = 119
Mass number = proton + Neutron
Neutron = Mass number — proton
Neutron = 302 — 119
Neutron = 183
The correct answer of the given question above would be FINGERPRINTS. Molds might be used for evidence such as fingerprints. This is now a possibility of replicating fingerprints which is called a fingerprint mold. Hope this is the answer you are looking for.
<u>Answer:</u> The molarity of the stock solution is 4.64 M
<u>Explanation:</u>
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the stock solution
are the molarity and volume of diluted solution
We are given:
Putting values in above equation, we get:
Hence, the molarity of the stock solution is 4.64 M
