Ineed with my chemistry homework. it says: dr. dahm wants to make 650 ml of a solution that has a ph of 4.3. if he is working with hydroazoic acid (hn3) calculate the number of grams he needs to use. ka=2.8 * 10^-5

c. electrical charges of ionic bonds.

i hoped this , can i get brainliest plzgod bless you

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

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.
