Which of the following reactions would result in the formation of a gaseous product?
Which of the following reactions would result in the formation of a gaseous product?
NaOH + HCl →
NH3 + HNO3 →
KHCO3 + HBr →
Ca(OH)2 + H3PO4 →

Respuesta :

The third reaction will form a gaseous product, CO₂
KHCO₃ + HBr → KBr + H₂O + CO₂

The  reaction that would result  in formation  of gaseous product  is


KHCO3  +  HBr  ( third  answer)


explanation

KHCO3  react with  HBr  to form  KBr ,  CO2  and H2O  according  to  the  below equation.


KHCO3 + HBr →  KBr  + CO2 + H2O

CO2 ( carbon (IV)  oxide)  is the gas that  is  formed   during   reaction.


other reaction does not produce a   a gas for example  NaOH +   HCl forms  NaCl  and H2O
