Arrange the ions N3-, O2-, Mg2 , Na , and F- in order of increasing ionic radius, starting with the smallest first. Arrange the

Bond [772]

Answer:

Order of increasing ionic radius starting from the smallest is

Mg2+ < Na+ < F- < O2- < N3-

Explanation:

Ionic radius is the distance between the nucleus and the electrons in the outermost shell of an ion. In the ions given about, it can be deducted that they all have the same number of electrons and are said to be isoelectronic. This shows us that they all have the same electrons and we can only seperate them by checking the respective charges on the ions. A more positive charge will have a smaller radius while a more negative will have a larger radius. This is because when an atom loses an electron and form a cation (+), the remaining electrons move closer to the nucleus and hence a smaller radius of the atom occurs. But when an atom gains n electron,it forms anion (-), the new electron leads to the shielding of the remaining electrons from the nucleus and a large radius of the atom occurs.

So therefore, the above ions all have 10 electrons in their shells and magnesium with atomic number 12 and having lost 2 electrons to become positively charge has the smallest radius compared to others.

Mg2+ = 12 protons, 10 electrons

Na+ = 11 protons, 10 electrons

F- = 9 protons, 10 electrons

O2- = 8 protons, 10 electrons

N3- = 7 protons, 10 electrons

N3- has the largest ionic radius and Mg2+ has the lowest ionic radius.

The order is thus, Mg2+ , Na+, F-, O2-, N3-

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.
