5K + KNO3 ------ 3K2O + N
masya89 [10]

Answer:

174,957.143 grams of potassium and 89,228.478 grams of potassium nitrate will be needed.

Explanation:

5K +KNO_3\rightarrow 3K_2O + N

Mass of nitrogen =  27 lbs = 12,247 g

1 lbs = 453.592 g

Moles of nitrogen = \frac{12,247 g}{14 g/mol}=874.786 mol

According to reaction, 1 mole of nitrogen is produced from 5 moles of potassium and 1 mole of potassium nitrate.

Then 874.786 mol of nitrogen will be obtained from :

\frac{5}{1}\times 874.786 mol=4,373.928 mol of potassium.

Then 874.786 mol of nitrogen will be obtained from :

\frac{1}{1}\times 874.786 mol=874.789 mol of potassium nitrate.

Mass of 4,373.928 moles of potassium:

4,373.928 mol\times 40 g/mol=174,957.143 g of potassium

Mass of 874.789 moles of potassium nitrate:

874.789 mol\times 102 g/mol=89,228.478 g of potassium nitrate

For each of the following substituents, indicate whether it withdraws electrons inductively, donates electrons by hyperconjugati
aleksandrvk [35]

Answer:

Br- Withdraws electrons inductively

       Donates electrons by resonance

CH2CH3 - Donates electrons by hyperconjugation

NHCH3- Withdraws electrons inductively

              Donates electrons by resonance

OCH3 -  Withdraws electrons inductively

              Donates electrons by resonance

+N(CH3)3 - Withdraws electrons inductively

                   

Explanation:

A chemical moiety may withdraw or donate electrons by resonance or inductive effect.

Halogens are electronegative elements hence they withdraw electrons by inductive effect. However, they also contain lone pairs so the can donate electrons by resonance.

Alkyl groups donate electrons by hyperconjugation involving hydrogen atoms.

-NHCH3  and contain species that have lone pair of electrons which can be donated by resonance. Also, the nitrogen and oxygen atoms are very electron withdrawing making the carbon atom to have a -I inductive effect.

+N(CH3)3 have no lone pair and is strongly electron withdrawing by inductive effects.
