Pomozcie !!

Answer 1

2HCOOH + 2K -> 2HCOOK + H₂
2HCOOH + MgO -> (HCOO)₂Mg + H₂O
2HCOOH + Ca(OH)₂ -> (HCOO)₂Ca + 2H2O
6HCOOH + 2Al -> 2(HCOO)₃Al + 3H₂(gaz)
6HCOOH + Fe₂O₃ -> 2(HCOO)₃Fe + 3H₂O
HCOOH + LiOH -> HCOOLi + H2O
2HCOOH + Na2O -> 2HCOONa + H2O
HCOOH -> HCOO- + H+ (nad strzałką woda)
2HCOOH + 02 -> 2CO2+ 2H2O

6HCOOH + 2Al -> 2(HCOO)₃Al + 3H₂(gaz)
6HCOOH + Fe₂O₃ -> 2(HCOO)₃Fe + 3H₂O
HCOOH + LiOH -> HCOOLi + H2O
2HCOOH + Na2O -> 2HCOONa + H2O
HCOOH -> HCOO- + H+
2HCOOH + 02 -> 2CO2+ 2H2O
