Hi, the internet says the electron negativity of ammonia is 3.04. But how is that possible? I thought you had to take the molecular formula, NH3, and then subtract 3.0 from H, which is 3.0 – (3•2.1). How do you do that correctly, or why is it 3.0? Thanks!

Loading...Calculate the pH value of an ammonia solution that has a mass concentration of 102.18 g/L. Given M(NH3)= 17.03 g/mol ; Ks= 5.6 ×10^-10 (mol/L)^2 My solution is: First I calculated the Pks value -log(Ks)=PKs= 9.25 rounded Pkb =14-9.25= 4.75 Then I calculated the substance concentration by calculating C=ß/ M and I got 6 mol/l…
Using the example of the reaction between hydrogen and iodine, explain the difference between the terms minimum energy and activation energy. I'm finding it a little difficult to separate the two concepts, for example, what energy is needed to break bonds or the energy required for a successful collision, etc.
Hi, I'm taking a chemistry test on Monday, and unfortunately, I don't understand the topic of chemical calculations at all! I'm currently doing an exercise that reads: Quantitative elemental analysis of 0.1000 g of a colorless organic liquid revealed 0.1882 g of carbon dioxide and 0.1188 g of water. The molar mass of the substance…
No, there is no! – Elements possess an EN value that reflects the desire to remove electron(density) from another atom.
Then you thought wrong. You look at the bonds between the individual atoms and determine the difference there. These numbers can then be used to determine whether a partial charge is present, etc.
Hello sophiareich19,
The electronegativity of N is with me 3.04. H is 2.2. That means that
ΔEN(N,H)= 3.0 – 2.1 = 0.84.
You do not calculate H three times but only once so that you can see if it is a dipole or not a trade, and where d- or d+ is.
There is no electronegativity of compounds therefore also not of ammonia! Electronegativities exist only for atoms. And with this one calculates the electro-negstivityDifference of a single Bond out.
The Internet also states that “on the Internet” is not a meaningful source. And that’s true, unlike the statement about NH3
Only atoms have an EN. Bindings have an EN difference. Verificationhave none of them.
