First step is to balance the amount of atoms on each side
So for example if my equation that I have to balance is : Br2 -> Br-
First thing I would have to do would be :
Br2 -> 2Br-
Then I would have to balance the charges on both sides. So because there is a -2 charge on the right side I will have to add a -2 charge onto the right side as well. I would do this by :
Br2 + 2e- -> 2Br-
And now you can see the amount of atoms and the charges are balanced... So your overall reaction is now balanced too.
When it is acted upon by an outside force
The temperature has the greatest effect i guess
Answer:
This question is incomplete
Explanation:
This question is incomplete but the answer to (1) and steps involved in calculating (2) and (3) will be discussed in the attachment
1. The reaction is an exothermic reaction because heat was given off. Exothermic reaction is a reaction in which heat is released from a reaction into the surroundings. And according to the question, the student observed <em>that the temperature of the water increased during the course of the minutes.</em>
Ionic. because MgcI2 is a compound of a metal and a non metal, which seems to form a ionic bonds together
