The overall reaction in a commercial heat pack can be represented as how much heat is released when 4.40 moles of iron are reacted with excess ? heat = kj how much heat is released when 1.00 mole of is produced? heat = kj how much heat is released when 1.60 g iron is reacted with excess ? heat = kj how much heat is released when 11.8 g and 1.20 g are reacted? heat = kj

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

The answer is 3.

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.
