Answer:
Electromagnetism is the study of the electromagnetic force, one of the four fundamental forces of nature. It includes the electric force, which pushes all charged particles, and the magnetic force, which only pushes moving charges.It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur.

tell me if this helped, ill try and explain better
Answer:
0.071 is the correct answer using the formula d=m/v
Answer:
The halogens are extremely reactive, whilst the noble gases are mainly inert.
Only some noble gases tend to form compounds, such as xenon and krypton. However, some like helium, almost have no compounds at all.
Noble gases also have octet rule shells, which causes the little reactivity associated with them.
To form bonds with noble gases, a lot of energy is required to form those bonds.
Halogens, on the other hand, are extremely reactive. Compounds like chlorine and fluorine must be stored carefully, as they will oxidise anything that they can find, just to get one extra electron to get an octet configuration.
Hope this helps :)
Answer : The mass of
is, 295.323 grams
Solution :
First we have to calculate the moles of
.

Now we have to calculate the moles of NaBr.
The balanced chemical reaction is,

From the balanced reaction we conclude that
As, 2 moles of
react with 2 moles of 
So, 2.87 moles of
react with 2.87 moles of 
Now we have to calculate the mass of NaBr.


Therefore, the mass mass of
is, 295.323 grams
Hello :)
Based on the information I received reading the picture, the answer should be “B”
Explanation: if I am wrong I’m very sorry. But that should be the answer
