Na 2 O+H 2 O="===2NaOH？" 2Na 2 O 2 +2H 2 O="===4NaOH+" O 2 ↑
(2) The barrel must be isolated from the air quickly, and the temperature of the materials in the barrel should be reduced to prevent explosion due to excessive temperature or the reaction of sodium with oxygen and water. You can soak the barrel in kerosene, and then carefully hand over the sodium metal in the barrel to professionals after landing.
(1) The residue after explosion contains Na, Na 2 O, Na 2 O 2, etc. The main chemical equations of the reaction in water are 2na+2h2o = = 2n NaOH+h2write, Na2O+H2O = = 2na2o2+2h2o = = 4 NaOH+.
(2) To prevent three barrels from exploding, we should consider two aspects: preventing sodium from reacting with substances in the air and reducing the temperature of sodium in the barrel.
