One reason JJ Thomson is important to study because... wich one is answer
1)he worked with many other scientists
2)he won lots of prizes
3)he used experiments and evidence

Idont know. if you want an answer you need to give us some context dude.

Is there any options, for this

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.

They have mobile charged particles.  i hope this : )good luck!
