Fission and fusion are alike in many ways. However, one difference is
Annette [7]

Explanation:

Fusion vs Fission

In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium. Both reactions release energy which, in a power plant, would be used to boil water to drive a steam generator, thus producing electricity.

Why doesnt iron burst into flames when it rusts
Katarina [22]
Rust does not have the properties to catch onto flames. However, if you light it on fire, then it would probably catch in flames but not instantly and will not continue to burn unless you have soaked it in oil or flammable object or substance. :) Hope this helps!

This equation is not balanced. Click on the coefficient we should change first.<br> help ASAP
horrorfan [7]

Answer:  The coefficient we should change first is for NO_{3}.

Explanation:

The given reaction equation is as follows.

Al + Ni(NO_{3})_{2} \rightarrow Al(NO_{3})_{3} + Ni

Here, number of atoms present on reactant side are as follows.

  • Al = 1
  • Ni = 1
  • NO_{3} = 2

Number of atoms present on the product side are as follows.

  • Al = 1
  • Ni = 1
  • NO_{3} = 3

To balance this equation, multiply Al by 2 and NO_{3} by 3 on reactant side. Also, multiply Al(NO_{3})_{3} by 2 and Ni by 3 on the product side.

Hence, the equation can be rewritten as follows.

2Al + 3Ni(NO_{3})_{2} \rightarrow 2Al(NO_{3})_{3} + 3Ni

Now, number of atoms present on reactant side are as follows.

  • Al = 2
  • Ni = 3
  • NO_{3} = 6

Number of atoms present on product side are as follows.

  • Al = 2
  • Ni = 3
  • NO_{3} = 6

Since, the atoms on both reactant and product side are same. Hence, it is now a balanced chemical equation.

Thus, we can conclude that the coefficient we should change first is for NO_{3}.
