Data given
Number of electron = 108
Number of neutron = 158
Required
Mass number=?
Solution
As we know that mass number = No of proton + No of neutron
In any neutral atom the number of proton is always equal to number of electron
So number of proton will be = 108
However the atom has +1 charge which means that one proton is less than no of electron so proton number is 107.
Put values in above formula, we will get
Mass number= 107+108
= 215 Mass number
Answer:
Mohammed should now <u>lift</u> the print from the surface to preserve it
Explanation:
In order to preserve fingerprint evidence as required by crime laboratory policies and criminal justice systems, for which we have digital photography, casting material, and latent print lifts, that can be used as secondary evidence
The ridges on the cast and lift can be photographed to serve as an additional secondary evidence
The processing of the latent print after photographing is dependent on the surface type and may include the creation of an impression on soap, paint, wax, clay or dust
Therefore, Mohammed used an enhancement technique that made a fingerprint visible on a lamp. He photographed the print. Mohammed should now <u>lift</u> the print from the surface to preserve it
The number of protons,neutrons,electrons, the way the are classified (earth metal, noble gas,meteoroids) and also the way they react.
one way it can mutate is if it spreads
Answer:
They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick.
Hope this helps!
