К2О->КОН->К2СО3->К2SO4 FE(OH)2->FEO->FECL2->FE(OH)2LI->LI2O->LIOH->LI3PO4BE->BEO->BE(NO3)2->BE(OH)2->BEO->BESO4​

Answer 1

Відповідь:

К2О+H2O=2KOH

2КОН+CO2=K2CO3+H2O

К2СО3+H2SO4=К2SO4 +CO2+H2O

FE(OH)2=FeO+H2O

>FEO+2HCI=FeCI2

FECL2+2NaOH=FE(OH)2  +2NaCI

4LI+O2=2Li2O

LI2O+H2O=2LiOH

3LIOH+H3PO4=LI3PO4 +3H2O

2BE+O2=2BeO

BEO+2HNO3=Be(NO3)2+H2O

BE(NO3)2+2KOH=Be(OH)2+2KNO3

BE(OH)2-=BEO+H2O

Answer 2

The given sequence appears to be a series of chemical reactions involving different elements and compounds. Let's break it down step by step: 1. K2O -> KON -> K2CO3 -> K2SO4: - The reaction starts with potassium oxide (K2O), which reacts with nitrogen monoxide (NO) to form potassium nitrite (KON) [[1]]. - Then, potassium nitrite reacts with carbon dioxide (CO2) to produce potassium carbonate (K2CO3) [[2]]. - Finally, potassium carbonate reacts with sulfuric acid (H2SO4) to yield potassium sulfate (K2SO4) [[3]]. 2. Fe(OH)2 -> FeO -> FeCl2 -> Fe(OH)2Li -> Li2O -> LiOH -> Li3PO4: - Iron(II) hydroxide (Fe(OH)2) undergoes dehydration to form iron(II) oxide (FeO) [[4]]. - Iron(II) oxide reacts with hydrochloric acid (HCl) to produce iron(II) chloride (FeCl2) [[5]]. - Iron(II) chloride reacts with lithium hydroxide (LiOH) to form iron(II) hydroxide lithium salt (Fe(OH)2Li) [[6]]. - The lithium salt of iron(II) hydroxide then undergoes a series of reactions to form lithium oxide (Li2O), lithium hydroxide (LiOH), and lithium phosphate (Li3PO4) [[7]]. 3. Be -> BeO -> Be(NO3)2 -> Be(OH)2 -> BeO -> BeSO4: - Beryllium (Be) reacts with oxygen (O2) to form beryllium oxide (BeO) [[8]]. - Beryllium oxide reacts with nitric acid (HNO3) to produce beryllium nitrate (Be(NO3)2) [[9]]. - Beryllium nitrate reacts with water (H2O) to yield beryllium hydroxide (Be(OH)2) [[10]]. - Beryllium hydroxide can undergo dehydration to form beryllium oxide (BeO) again [[11]]. - Finally, beryllium oxide reacts with sulfuric acid (H2SO4) to produce beryllium sulfate (BeSO4) [[12]]. Please note that the given sequence of reactions may not represent a complete and accurate representation of the chemical reactions. It is always important to consult reliable sources and conduct proper experiments to verify the reactions. Let me know if there's anything else I can help you with!
