Question

HBr + NaOH -Fe + H2SO4 -K20+ H2O -NaOH + FeCl2 =​

Answer 1

HBr + NaOH --> NaBr + H2O

Fe + H2SO4 --> FeSO4 + H2↑

K2O + H2O --> 2KOH

2NaOH + FeCl2 --> 2NaCl + Fe(OH)2↓

Answer 2

The chemical equation you provided seems to be incomplete or contains some errors. Let's break it down and try to correct it step by step.

1. HBr + NaOH: This is a neutralization reaction between hydrobromic acid (HBr) and sodium hydroxide (NaOH). The correct balanced equation for this reaction is:

HBr + NaOH → NaBr + H2O

2. Fe + H2SO4: This appears to be a single displacement reaction between iron (Fe) and sulfuric acid (H2SO4). The balanced equation for this reaction is:

Fe + H2SO4 → FeSO4 + H2

3. K20 + H2O: This equation is incomplete or contains an error. K20 is not a valid chemical formula. Please provide the correct information, and I can assist you further.

4. NaOH + FeCl2: This seems to be another neutralization reaction between sodium hydroxide (NaOH) and iron(II) chloride (FeCl2). The balanced equation for this reaction is:

2NaOH + FeCl2 → 2NaCl + Fe(OH)2

Please review the information and provide any missing or corrected equations so that I can assist you more accurately.
