Answer:

Ammonium chloride has ammonium (NH4 +) part which is slightly acidic and Barium Hydroxide is a strong base.

You can see that an acid-base reaction will occur.

In this case :

Its highly endothermic reaction

Forms aqueous ammonia (mind that ammonia is highly water soluble gas so no effervesence) and Barium Chloride which is water soluble.

Ba(OH)2 +NH4Cl ——->BaCl2 + NH3 +H2O (unbalanced)

Marshall determines that a gas has a gauge pressure of 276 kpa what's the absolute pressure of the gas

omeli [17]

A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.
