Question

V2O5 + Mg(OH)2 →, HgO +HJ → , K2CO3 + Pb(NO3)2 →, ZnSO3 + H2SO4 →, Ca(OH)2 + HCl →, Na + P →

Answer 1

V205+Mg(OH)2=MgO=H3VO4 

2HJ+HgO=Hg+H2O+I2

 

 Pb(NO3)2 + K2CO3 = Pb(CO3)

ZnSO3 + H2SO4 = ZnSO4 + SO2 + H2O

 Ca(OH)2 + 2 HCl = CaCl2 + 2 H2O

 

Answer 2

V2O5 + Mg(OH)2 → HgO + HJ

In this reaction, V2O5 (vanadium pentoxide) reacts with Mg(OH)2 (magnesium hydroxide) to produce HgO (mercury(II) oxide) and HJ (hydrogen iodide). The balanced equation for this reaction is:

V2O5 + 2Mg(OH)2 → HgO + 2HJ

K2CO3 + Pb(NO3)2 → ZnSO3 + H2SO4

In this reaction, K2CO3 (potassium carbonate) reacts with Pb(NO3)2 (lead(II) nitrate) to produce ZnSO3 (zinc sulfite) and H2SO4 (sulfuric acid). The balanced equation for this reaction is:

2K2CO3 + Pb(NO3)2 → ZnSO3 + H2SO4 + 2KNO3 + PbCO3

Ca(OH)2 + HCl → CaCl2 + H2O

In this reaction, Ca(OH)2 (calcium hydroxide) reacts with HCl (hydrochloric acid) to produce CaCl2 (calcium chloride) and H2O (water). The balanced equation for this reaction is:

Ca(OH)2 + 2HCl → CaCl2 + 2H2O

Na + P → NaP

In this reaction, Na (sodium) reacts with P (phosphorus) to produce NaP (sodium phosphide). The balanced equation for this reaction is:

3Na + P → NaP
