Answer:
Explanation:
So , these molecules would want to fill up their shell in order to become stable, which means they would want a total of 8 electrons.
As you can see in the first example, the Carbon has 4 electrons (one dot on each side of the C), however this is not enough as it has not reached 8, so it is unstable. The Carbon would want a full pair of electrons, however it only has a lone electron as there is only one electron per side.
To become stable, it would require 4 more electrons, and as you can see, there are 4 hydrogens, which have one electron each. that means there is a total of 4 hydrogens.
So, the hydrogens and carbon would bond, and the Hydrogen would share one of its electrons to the carbon so it can have a full pair.
Same concept for ammonia
Nitrogen has 5 electrons (meaning it requires 3 more to reach 8) , and 3 of the electrons are lone and need one more to complete the pair. So, the Hydrogen would provide these 3 electrons by joining up with N where there is only one dot on the N.
Hope it makes sense ,
you could search "electron dot diagram for NH3 " to see how it looks
Because they don’t have the same elements i guess, what is question 1?
Answer:
D always different between different substances.
Explanation:
Answer:- Formula of the hydrate is and it's name is Iron(III)sulfate pentahydrate.
Solution:- As per the given information, there is 18.4% water in the hydrate. If we assume the mass of the hydrate as 100 grams then there would be 18.4 grams of water and 81.6 grams of Iron(III)sulfate present in the hydrate.
Molar mass for Iron(III)sulfate is 399.88 gram per mol and the molar mass for water is 18.02 gram per mol.
We will calculate the moles of Iron(III)sulfate and water present in the compound on dividing their grams by their molar masses as:
=
=
Now, the next step is to calculate the mol ratio and for this we divide the moles of each by the least one of them means whose moles are less. Here, the moles of Iron(III)sulfate are less than moles of water. So, we divide the moles of each by 0.204.
= 1
= 5
There is 1:5 mol ratio between Iron(III)sulfate and water. So, the formula of the hydrate is and the name of the hydrate is Iron(III)sulfate pentahydrate.
