Answer:
In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.
Explanation:
The process involving separation of liquid/solid mixture as regards this question is Decantation.
- Decantation can be regarded as one of the process used in separation of liquid from solid as well as other immiscible (non-mixing) liquids through the removal of the liquid layer that is present at the top from the layer of solid/liquid which present at the below.
- In the process, the liquid will be poured slowly into another vessel as the pouring continues, then the solid will settle in the original vessel.
- This process can be done through tilting the mixture after the the top layer have been poured out.
<em>Therefore, decantation is one of the separation technique.</em>

Answer:
No limiting reagent. There is an exact amount of each.
Explanation:
Start by getting the equation
Fe + O2 -> Fe2O3
If you balance the oxygens the Fe will easily follow.
Fe + 3O2 => 2Fe2O3
So far what you have is 6 oxygens on the right and 6 on the left. Now all you need do is balance the irons. The are 4 on the right (2Fe2). So you must have 4 on the left.
4Fe + 3O2 -> 2Fe2O3
Now to your question if you have 4 mols of iron, you need 3 mols of O2. Those are the balance numbers of the equation. They also represent mols.
There is no limiting reagent in the theoretical world of chemistry. All the iron will be used up and so will the given amount of oxygen.
Answer: 2hqu
Explanation: because you have to add them
6,02×10²³ * 3,2 = 19,264×10²³=1,9264×10²⁴
