Pendahuluan
Kiimikada, mid ka mid ah fikradaha aasaasiga ah ee inta badan laga hadlo waa falgalka xaddidan. Falgalka xaddidan waa qaybta ku jirta falgalka kiimikada oo marka hore la isticmaali doono, sidaas darteedna, go'aamisa xaddiga badeecada la soo saari karo. Fahmidda falgalka xaddidan waa muhiim sababtoo ah waxay naga caawineysaa inaan saadaalino natiijada falgalka kiimikada iyo hufnaanta isticmaalka kiimikada ee warshadaha ama shaybaarka.
Xaddidaadda Fikradda Reagent
Marka la eego dhinaca wax-qabadka, waxa lagu sawiri karaa wax-soo-saarka xaddidaya iyadoo la adeegsanayo tusaale. Ka soo qaad inaan rabno inaan samayno sandwiches oo leh laba maaddooyin oo waaweyn: rooti iyo hilib. Haddii aan haysanno 10 xaleef oo rooti ah laakiin aan haysanno 3 xaleef oo hilib ah, waxaan samayn karnaa ugu badnaan 3 sandwiches. Xaaladdan oo kale, hilibku waa maaddada xaddidaysa, inkastoo weli ay harsan tahay rooti.
Marka laga hadlayo kiimikada, isla fikradda ayaa khuseysa. Marka laba ama in ka badan oo fal-celin ah ay falceliyaan, mid ka mid ah ayaa marka hore dhammaan doona, taasoo xaddidaysa xaddiga badeecada la samayn karo. Fal-celintan waxaa markaa loo yaqaan fal-celinta xaddidan.
Aqoonsiga Falcelinta Xaddidaya ee Falcelinta Kiimikada
Si loo aqoonsado fal-celinta xaddidan ee fal-celinta kiimikada, waxaan isticmaali karnaa tallaabooyinka soo socda:
1. Qor oo isku dheelitir isla'egta kiimikada ee falcelinta.
2. Xisaabi tirada burooyinka fal-celinta kasta oo la heli karo.
3. Adeegso stoichiometry (saamiga mole) ee isle'egta dheellitiran si aad u go'aamiso xaddiga badeecada uu soo saaro fal-celiye kasta haddii si buuxda loo isticmaalo.
4. Soo saar fal-celinta soo saarta xaddiga ugu yar ee badeecada. Fal-celintan ayaa ah fal-celinta xaddidan.
Su'aalo iyo Doodo Tusaale ah
Su'aal 1aad
Marka la eego falcelinta soo socota:
\[ 2 \qoraal{H}_2 + \qoraal{O}_2 \qoraal 2 \qoraal{H}_2\qoraal{O} \]
Haddii aan ku bilowno falgalka 5 moles oo H₂ ah iyo 2 moles oo O₂ ah, go'aami falcelinta xaddidan iyo inta moles ee H₂O la soo saari doono.
Dood:
1. Qor oo isku dheelitir isle'egyada kiimikada:
\[ 2 \qoraal{H}_2 + \qoraal{O}_2 \qoraal 2 \qoraal{H}_2\qoraal{O} \]
2. Xisaabi tirada burooyinka falgalka kasta:
– \( \text{H}_2 \) = 5 mol
– \( \text{O}_2 \) = 2 mol
3. Adeegso stoichiometry si aad u go'aamiso xaddiga badeecada uu soo saari karo fal-celiye kasta:
– Laga bilaabo 5 mol H₂:
\[ \text{Cadadka H₂O ee la samayn karo} = 5 \text{ mol H}_2 \times \frac{2 \text{ mol H}_2\text{O}}{2 \text{ mol H}_2} = 5 \text{ mol H}_2\text{O} \]
– Laga bilaabo 2 baal oo O₂ ah:
\[ \text{Cadadka H₂O ee la samayn karo} = 2 \text{ mol O}_2 \times \frac{2 \text{ mol H}_2\text{O}}{1 \text{ mol O}_2} = 4 \text{ mol H}_2\text{O} \]
4. Falgaliyaha soo saara xaddiga ugu yar ee badeecada waa \( \text{O}_2 \). Markaa, \( \text{O}_2 \) waa falgalaha xaddidan, xaddiga H₂O ee la soo saari karona waa 4 moles.
Su'aal 2aad
Marka la eego falcelinta soo socota:
\[ 4 \text{Al} + 3 \text{O}_2 \rightarrow 2 \text{Al}_2\text{O}_3 \]
Haddii aan ku bilowno 8 moles oo Al ah iyo 4 moles oo \( \text{O}_2 \), go'aami falcelinta xaddidan iyo inta moles ee \( \text{Al}_2 \text{O}_3 \) la soo saaray.
Dood:
1. Qor oo isku dheelitir isle'egyada kiimikada:
\[ 4 \text{Al} + 3 \text{O}_2 \rightarrow 2 \text{Al}_2\text{O}_3 \]
2. Xisaabi tirada burooyinka falgalka kasta:
– \( \text{Al} \) = 8 mol
– \( \text{O}_2 \) = 4 mol
3. Adeegso stoichiometry si aad u go'aamiso xaddiga badeecada uu soo saari karo fal-celiye kasta:
– Laga soo bilaabo 8 moles oo Al ah:
\[ \text{Amount } \text{Al}_2\text{O}_3 \text{ oo la samayn karo} = 8 \text{ mol Al} \times \frac{2 \text{ mol } \text{Al}_2\text{O}_3}{4 \text{ mol Al}} = 4 \text{ mol } \text{ Al}_2\text{O}_3 \]
– Laga bilaabo 4 moles oo ah \( \text{O}_2 \):
\[ \text{Amount } \text{Al}_2\text{O}_3 \text{ oo la samayn karo} = 4 \text{ mol } \text{O}_2 \times \frac{2 \text{ mol } \text{Al}_2\text{O}_3}{3 \text{ mol } \text{O}_2} = 2.67 \text{ mol } \text{Al}_2\text{O}_3 \]
4. Falgaliyaha soo saara xaddiga ugu yar ee badeecada waa \( \text{O}_2 \). Markaa, \( \text{O}_2 \) waa falgalaha xaddidan, xaddiga \( \text{Al}_2 \text{O}_3 \) ee la soo saari karo waa 2.67 mol.
Su'aal 3aad
Marka la eego falcelinta soo socota:
\[ \qoraalka{N}_2 + 3\qoraalka{H}_2 \rightarrow 2\qoraalka{NH}_3 \]
Haddii aan ku bilowno 6 mol \( \text{N}_2 \) iyo 18 mol \( \text{H}_2 \), go'aami falcelinta xaddidan iyo inta moles ee \( \text{NH}_3 \) la soo saaray.
Dood:
1. Qor oo isku dheelitir falcelinta kiimikada:
\[ \qoraalka{N}_2 + 3\qoraalka{H}_2 \rightarrow 2\qoraalka{NH}_3 \]
2. Xisaabi tirada burooyinka falgalka kasta:
– \( \text{N}_2 \) = 6 mol
– \( \text{H}_2 \) = 18 mol
3. Adeegso stoichiometry si aad u go'aamiso xaddiga badeecada uu soo saari karo fal-celiye kasta:
– Laga bilaabo 6 moles \( \text{N}_2 \):
\[ \text{Amount } \text{NH}_3 \text{ oo la samayn karo} = 6 \text{ mol } \text{N}_2 \times \frac{2 \text{ mol } \text{NH}_3}{1 \text{ mol } \text{N}_2} = 12 \text{ mol } \text{NH}_3 \]
– Laga bilaabo 18 mol \( \text{H}_2 \):
\[ \text{Amount } \text{NH}_3 \text{ oo la samayn karo} = 18 \text{ mol } \text{H}_2 \times \frac{2 \text{ mol } \text{NH}_3}{3 \text{ mol } \text{H}_2} = 12 \text{ mol } \text{NH}_3 \]
4. Tirada ugu badan ee badeecada la soo saaray waa isku mid labada falgale, laakiin aragti ahaan xaddiga xaddidan ee badeecaddu waa \( \text{H}_2 \), si \( \text{H}_2 \) uu u noqdo falgale xaddidan.
