4. Given: S (s) + O2 (g) → SO2 (g) 2 S03 (g) → 2 SO2 (g) + O2 (g)
Find AH° for: 2 S(s) + 3 O2(g) → 2 S03(g)
AH° = -296.1 kJ
AH° = 198.2 kJ

I’m guessing you’re more alert to yourself or your surroundings if you’re more concentrated

The answer is 65.3312

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.

A. pipe, good luck, hope you get it right
