What do the quantum numbers of electrons represent?
soldier1979 [14.2K]
It represents The number of subshells, or , describes the shape of the orbital. Itcan also be used to determine the number of angular nodes. The magnetic quantum number, ml, describes the energy levels in a subshell, and ms refers to the spin on the electron, which can either be up or down.

A chemical company makes ammonia by reacting nitrogen with hydrogen. The company needs to make 70 batches of ammonia for a clien
RSB [31]

Answer:- No, the company would not be able to full fill the order.

Solution:- The balanced equation for the formation of ammonia by the reaction of hydrogen with nitrogen is:

3H_2+N_2\rightarrow 2NH_3

We have been given with 22000 grams of nitrogen and 1000 grams of hydrogen. Let's convert grams of each to moles:

moles of nitrogen = 22000g N_2(\frac{1mol}{28g})

moles of nitrogen = 785.71 mol

moles of hydrogen = 1000g H_2(\frac{1mol}{2g})

moles of hydrogen = 500 mol

From balanced equation 3 moles of hydrogen react with 1 mol of nitrogen. Let's calculate how many moles of nitrogen would react with 500 mol of hydrogen:

500mol H_2(\frac{1mol N_2}{3mol H_2})

= 166.67 mol N_2

166.67 moles of nitrogen are required and 785.71 moles of it are available. It means nitrogen is in excess and hydrogen is limiting. Product yield depends on limiting reactant. So, let's calculate the amount of ammonia formed from moles of hydrogen as:

500mol H_2(\frac{2mol NH_3}{3mol H_2})(\frac{17g NH_3}{1mol NH_3})

= 5666.67g of ammonia

let's convert the grams of ammonia to number of batches as:

5666.67g NH_3(\frac{1 batch}{175g NH_3})

= 32 batches

Company needs to make 70 batches of ammonia but from given amounts of hydrogen and nitrogen only 32 batches could be made. It means the company would not be able to full fill the order.

Which type of hybridization leads to a trigonal planar electron domain geometry? s sp sp2 sp3
kolezko [41]
Electron domain geometry takes into account the bonds and the free electrons around the atom to predict the geometry.

A tigonal planar geometry means that all the electron domains are in the plane and that they are as far away as they can. That means that there are three electron domains in the plane separated at 120 ° each other.

sp2 means that there are three hybrid electron domains, and the geometrh that leads to the minimal repulsion force is they placed at 120°, which exactly the trigonal planar geometry described up.

Then the answer is sp2

You can check in your book, that sp corresponds to two domains, located linearly, at 180°; and sp3 is four domains with the form of tetrahedral with 109.5° angles.
