Hydrogen bonding is necessary for

1 answer:

3 0

Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies

The coordination sphere of a complex consists of ________. The coordination sphere of a complex consists of ________. the ligand

sammy [17]

Answer:

The coordination sphere of a complex consists of the central metal ion and the ligands bonded to it.

Explanation:

The Coordination Compounds are sets of a central metal ion attached to a group of molecules or ions that surround it. They are also called metal complexes or simply complexes. Then they are compounds that have a central atom surrounded by a group of molecules or ions, the latter called ligands.

The central atom must have empty orbitals capable of accepting pairs of electrons, with the transition metals being the ones with the greatest tendency. Because of this, they can act as Lewis acids (electron pair acceptors). The ligands have unshared electron pairs, then acting as Lewis bases (electron pair donors).

When forming a complex, it is said that the ligands coordinate to the metal and the central metal and the ligands attached to it constitute the coordination sphere of the complex.

Finally, the coordination sphere of a complex consists of the central metal ion and the ligands bonded to it.

How many grams of a 34.2% potassium sulfate solution would contain 274.4 g potassium sulfate?

mart [117]

$34,2\% \ \ \ \ \rightarrow \ \ \ 274,4g\\
100\% \ \ \ \ \ \ \rightarrow \ \ m_{x}\\\\
m_{x}=\frac{274,4g*100\%}{34,2\%}\approx 802,34g$

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.
