Use the following reaction to answer question 8-10
4Al + 3O2 → 2Al2O3
What is the limiting reagent and how many grams of aluminum oxide can be produced when 15g of aluminum reacts with 5g of oxygen?

How many grams of aluminum are needed to make 2.2 moles of aluminum oxide?

10) How many moles of oxygen are needed to react with 46.3g of aluminum?

Hope you find the answer

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

Naoh + hbr -> nabr (salt) + h2o ca (oh)2 + 2hbr - - - > ca (br)2 + 2h2o

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.
