Two elements x and y are stored under water and kerosene oil, respectively. when small piece of each element is left open in air, both start warming up. the product in each case is dissolved in water. the solution from the residue x was found to be acidic while that of residue y was basic.
a. identify elements x and y. support your answer with suitable explanation.
b. write the balanced equation for the reaction of elements x and y on exposure to air
c. write balanced equation for reaction of products formed in (b) with h2o

a) X is phosphorus because it is kept in water and hence it is a non metal it's solution will be acidic and Y Is sodium because it is metal stored in kerosene oil to prevent accidental fires and since it a metal it's solution will be basic.
b) i)4Na+O2 = 2Na2O
ii) 4P+3O2 = 2P2O3
When both react with each other then
3Na + P = Na3P
C) i) Na2O + h2O = 2naoh
ii) P2O3 + 3H2O = 2H3PO3
b) i)4Na+O2 = 2Na2O
ii) 4P+3O2 = 2P2O3
When both react with each other then
3Na + P = Na3P
C) i) Na2O + h2O = 2naoh
ii) P2O3 + 3H2O = 2H3PO3
