The unbalanced equation?2 Na2O2(s) + 2 H2O(ℓ) −→ 4 NaOH(aq) + O2(g) 27 g Na2O2 x 1 mol / 78 g = 0.346 mol Na2O2 0.346 mol Na2O2 x 1 O2 / 2 Na2O2 = 0.173 mol O2 0.173 mol O2 x 32.0 g / mol = 5.5 g O210 g of Sodium peroxide Na2O2 reacts with H2O to produce oxygen and sodium hydroxide. If …
Essentially, the heavier the alkaline earth metal, the more vigorously it will react with water. The alkaline earth metals (highlighted) occupy group two in the periodic table Magnesium is the fifth most abundant element on earth, closely followed by calcium in eigth place - which is just as well, since both magnesium and calcium are vital to all living things, including human beings!
Involves the calcination of limestone at 1000 oc to produce calcium oxide cao and carbon dioxide gas co 2 the cao 2 will be burned with carbon at 2000oc to produce calcium carbide cac 2 the calcium carbide subsequently reacts with water to generate acetylene
