Answer:
Claim 1
Explanation:
I chose this claim because I believe that when the plates under the earth move or shift, that's what causes an earthquake and when everything starts to shake. If it was the other way around there wouldn't be any reason for an earthquake to start.
hope that helped :)
Answer:
MgCl₂ + H₂ ---> 2 HCl + Mg
Explanation:
Since you have not given any products, I am going to assume that this is a single-displacement reaction. In these types of reactions, an element is being swapped for another in a compound. The unbalanced equation would look like this:
MgCl₂ + H₂ ---> HCl + Mg
Mg does not have a subscript of 2 because it can exist by itself. As you can see, the reaction is not balanced. On the left side, there is 1 Mg, 2 Cl, and 3 H. On the right side, there is only 1 of each. The balanced equation would look like this:
MgCl₂ + H₂ ---> 2 HCl + Mg
Now, there is 1 Mg, 2 Cl, and 2 H on both sides.
Answer : and are the ions formed from the NaCl salt dissolve in water.
Explanation :
The NaCl salt is formed when positive sodium ions bonded to the negative chloride ions.
When NaCl dissolves in water, the negative part of water attract the positive sodium ions and positive part of water attract the negative chloride ions.
