Question

Большая просьба помогите срочно решить !!! Определите, какие реакции будут протекать. Напишите их уровнения и назовите все вещества по междунородной номенклотуре.SO2 + Sr(OH)2 ->FeO + KOH ->K2CO3 + Pb(NO3)2 ->Zn(h2po4)2 +Zn(OH)2 ->2CuSO4 + 2NaOH ->Ca + HMnO4 ->Очень нужно на днях сдавать БУДУ ОЧЕНЬ Благодарен!

Answer 1

 SO2 + Sr(OH)2 = SrSO3 + Н2O (сульфид стронция и вода)
FeO + KOH - реакция не идёт

K2CO3 + Pb(NO3)2 = 2KNO3 + PbCO3 (нитрат калия и карбонат свинца(II))

CuSO4 + 2NaOH = Сu(OH)2 + Na2SO4(гидроксид меди(II) и сульфат натрия)

Ca + HMnO4= Ca(MnO4)2 + H2(перманганат кальция и водород)
 

Answer 2

Chemical Reactions and Equations

1. Reaction between SO2 and Sr(OH)2: - The reaction between sulfur dioxide (SO2) and strontium hydroxide (Sr(OH)2) does not result in a simple chemical reaction. Therefore, no balanced chemical equation can be provided for this combination.

2. Reaction between FeO and KOH: - When iron(II) oxide (FeO) reacts with potassium hydroxide (KOH), it forms potassium ferrous hydroxide (K2Fe(OH)4). - The balanced chemical equation for this reaction is: ``` FeO + 2KOH -> K2Fe(OH)4 ```

3. Reaction between Pb(NO3)2 and Zn(H2PO4)2: - When lead(II) nitrate (Pb(NO3)2) reacts with zinc dihydrogen phosphate (Zn(H2PO4)2), it forms lead(II) phosphate (Pb3(PO4)2) and zinc nitrate (Zn(NO3)2). - The balanced chemical equation for this reaction is: ``` 3Pb(NO3)2 + 2Zn(H2PO4)2 -> Pb3(PO4)2 + 2Zn(NO3)2 + 2HNO3 ```

4. Reaction between Zn(OH)2 and CuSO4: - When zinc hydroxide (Zn(OH)2) reacts with copper(II) sulfate (CuSO4), it forms zinc sulfate (ZnSO4) and copper(II) hydroxide (Cu(OH)2). - The balanced chemical equation for this reaction is: ``` Zn(OH)2 + CuSO4 -> ZnSO4 + Cu(OH)2 ```

5. Reaction between 2NaOH and Ca: - When sodium hydroxide (NaOH) reacts with calcium (Ca), it forms sodium calcium hydroxide (Na2Ca(OH)4). - The balanced chemical equation for this reaction is: ``` 2NaOH + Ca -> Na2Ca(OH)4 ```

6. Reaction between HMnO4 and Ca: - The reaction between potassium permanganate (HMnO4) and calcium (Ca) does not result in a simple chemical reaction. Therefore, no balanced chemical equation can be provided for this combination.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
