Answer:
The reactivity of the halogen group (group 17) decreases
from top to bottom within the group. Fluorine is the
most reactive halogen, while iodine is the least. Since
chlorine is above <em><u>bromine</u></em>, it is more reactive than
bromine and can replace it in a halogen replacement
reaction.

Hello!
The property that is being demonstrated when Janice was given a mixture of alcohol and water and her teacher told her that she could use temperature to separate these compounds is boiling.
The boiling point is the temperature when a substance goes from liquid state to gas state. If two liquid substances with different boiling points are in a mixture, they can be separated by heating one of them to its boiling point and condensing the gas in another container in a process called distillation. The difference in boiling points of alcohols (usually lower than water) and water allows to separate them in a mixture.
Have a nice day!
Answer:
Mutualism
Explanation:
In Mutualism, both parties benefit.
No. Of protons = mass no. - no. Of neutrons
No. Of protons = 67 - 37
= 30
No. Of electrons = 28
Zinc will have 30 protons and 28 electrons. So, it will have +2 charge
Symbol - Zn^+2
