Which of the following displays the correct change in enthalpy and best describes the reaction below? 2CsCl(aq) + Na2SO4(aq) - 2NaCl(aq) + CS2SO4(aq)
Given:
CS2SO4: AH=-1400 kJ
CSCI: AH= -415 kJ
Na2SO4: AH= -1380 kJ
NaCI: AH = -411 kJ
OA. It is exothermic and AH = -12 kJ.
OB. It is exothermic and AH = -16 kl.
Ос.
It is endothermic and AH = -12 k).
OD.
It is endothermic and AH = -16 kJ.

Idon’t know what the answer is i wish i could

Ithink ahopefully im correct 

Try adding 700% because of the x in y

The reaction 2kalsi3o8 + 2(h+ + hco3-) + h2o  →  al2si2o5(oh)4 + 2k+ + 2hco3- + 4sio2 shows that feldspar kalsi3o8 is chemically altered by hydrolysis to form chalky-looking clay mineral kaolinite al2si2o5(oh)4. the chemical breakdown of potassium feldspar due to exposure to acidic water results to the mineral binding with the water molecule to become kaolinite with silica and potassium and bicarbonate ions in solution.
