Complete and balance each of the following equations for gas evolution reactions.?

HERE THE ANSWERS πŸ‘‡

  • 1: HBr(aq)+NaHCO3(aq)β†’

    When hydrogen combines with a bicarbonate ion, the product is hydrogen carbonate. This decomposes to produce carbon dioxide and water. The other product is sodium bromide.

    HBr(aq)+NaHCO3(aq) β†’ H2O + CO2 (g) + NaBr

    2: NH4I(aq)+KOH(aq)β†’

    When an ammonium ion and a hydroxide ion combine, the product is ammonium hydroxide. This will decompose to produce ammonia and water.

    NH4I(aq)+KOH(aq)β†’ KI (aq) + NH3 ( g) + H2O

    3: HNO3(aq)+K2SO3(aq)β†’

    When hydrogen combines with a sulfite ion, the product is called sulfurous acid. This will produce sulfurous acid. This will decompose to produce sulfur dioxide gas and water.

    HNO3(aq)+K2SO3(aq)β†’ KNO3(aq)β†’ + SO2 (g) + H2O

    To balance this reaction, we need two nitric acid and two potassium nitrate.

    2 HNO3(aq)+K2SO3(aq)β†’2 KNO3 (aq)β†’ SO2 (g) + H2O

    4: HI(aq)+Li2S(aq)β†’

    In this reaction, the gas is hydrogen sulfide. (H2S)

    HI(aq)+Li2S(aq)β†’ H2S (g) + LiI (aq)

    To balance this reaction, we need 2 HI and 2 LI.

    2 HI(aq)+Li2S(aq)β†’ H2S (g) + 2 LiI (aq)

    I hope this is helpful for you.

  • HBr(aq) + NaHCO3(aq) ===β‡’ NaBr(aq) + H2O(l) + CO2(g)

    NH4I(aq) + KOH(aq) ==β‡’ KI(aq) + H2O(l) + NH3(g)

    2HNO3(aq) + K2SO3(aq) =β‡’ 2KNO3(aq) + H2O(l) + SO2(g)

    2HI(aq) + Li2S(aq) ==β‡’ 2LiI(aq) + H2S(g)
