1p is not possible because it goes like this 1s2 2s2 2p6
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:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

I hope it helps plz let me know if it is right or wrong.</h2>
For, ClO3- there are 26 valence electrons, so total pairs of electrons are 13.
True that in the preindustrial era, settlements were more likely to be near sources of surface water than in the industrial era. The main reason being that during the preindustrial era people were dependent mostly on irrigation. For irrigation people were dependent on surface water. This was the main and basic reason.
