Answer:
See attached picture.
Explanation:
Hello,
In this case, accounting for the IUPAC rules for the nomenclature of ketones, for the given name the structure is shown on the attached picture wherein the methyl is seen at the fourth carbon and the carbonyl at the second one in the 7-carbon chain.
Best regards.
Explanation:
We assume you are converting between grams ZnSO4 and mole. You can view more details on each measurement unit: molecular weight of ZnSO4 or mol This compound is also known as Zinc Sulfate. The SI base unit for amount of substance is the mole. 1 grams ZnSO4 is equal to 0.0061941519772353 mole.
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
D. Hypothesis Formation I hope this help ☺
Answer:
No
Explanation:
the dissolution of potassium nitrate in water is an endothermic process because hydration energy does overcome the lattice energy and hence it is not spontaneous at all temperature.
Hydration energy: it is a energy released when gaseous ion is dissolve in the water during dissolution it releases.
lattice energy: the energy which is released when one of ionic compound is formed from their gaseous ion is called lattice energy.
thats why to break it we should give minimum this much energy
