Question

Under the hood, a red piece of phosphorus should be placed into a deflagrating spoon. The phosphorus should be ignited in the flame of a bunsen burner. The spoon will then be insderted into a wide, clean mouth bottle containing 5 mL of H2O. This will collect some of the reaction product in the bottle. Once the burning has ceased, the spoon will be removed and the bottle covered with a glass plate.

a. What is the reaction type of this situation (synthesis, single, double, etc...)?

b. What is the word equation?

c. What is the balanced equation?

Explanation / Answer

Solution :- The phosphorous is burned to form the P2O5 and then it is combined with water it forms the phosphoric acid

a. type of the reaction is the synthesis reaction.

b. word equation is as follows

Phoshporous pentaoxide + water ------ > Phosphoric acid

c. Balanced reaction equatiuon is as follows

P2O5 + 3H2O   -------- > 2H3PO4
