Two students investigated the reaction of marble chips with hydrochloride acid. In the first minute of the reaction, 0.8 g of carbon dioxide gas was produced . Calculate the mean rate

Qrepresents joules in the formula

If this is a true or galse then its true but if not then what is the question?

Answeropposite;

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.
