B 2
is which shell are the valence electrons of the elements in period 2 found
Answer: 368 grams of sodium reacted.
Explanation:
The balanced reaction is :
According to stoichiometry :
2 moles of 
are formed from = 2 moles of 
Thus 16 moles of are formed from=
of
Mass of 
Thus 368 grams of sodium reacted.
Answer: Gas. Gas vibrates and move freely at high speeds.
Explanation:
The columns of the periodic table, also referred to as "groups" contain elements with similar reactive properties, due to these elements having a similar configuration of electrons in their outer shell.
Answer:
Advantages - less chances of developing resistant strains, less cost, less side effects, allowing the body to mount immune response
Disadvantages - inadequate/incomplete cure leading to complications, longer stay in the hospital
