5.2 moles of nitrogen gas are contained in a 3.4 L container. If pressure is kept constant what is the final molar amount of gas present in the container if gas is added until the
volume has decreased to 2000 mL?

Idon't know hope someone you

I’m not sure about this question

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.
