Answer:
Synthesis reaction
Explanation:
Chemical equation:
P₄ + O₂ → P₂O₃
Balanced chemical equation:
P₄ + 3O₂ → 2P₂O₃
Phosphorus and oxygen chemically combined to form phosphorus oxide.
The given reaction is synthesis reaction.
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
The reaction is completely balanced so this reaction is also follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
