5 0

Explanation:

  1. an element is a substance which cannot be spilt upto two or more simple substances.For eg gold,silver
  2. a compound is the substance produced by the union of two or more elements in a definite proportion by weight .For eg water,carbon dioxide
  3. I dont know
  4. A mixture is a substance formed by mixing two or more elements are compounds in any proportion by mass .Its types are:Hetregeneous mixture and homogeneous mixture.

  • the difference between mixture and compound is that a mixture is a substance formed by mixing two or more elements are compounds in any proportion by maths and compound is a substance produced by the union of two or more elements in a definite proportion by weight.

Phosphorus + iron(lll) oxide=tetraphosphorus decoxide + iron
Soloha48 [4]

Answer:

12~P (s) + 10~Fe_2O_3 (s)\rightarrow 3~P_4O_{10} (s) + 20~Fe (s)

Explanation:

Before writing this equation in a molecular equation form, let's identify each species:

  • phosphorus is a non-metal represented by 'P', it is solid at standard conditions;
  • iron(III) oxide is an ionic compound consisting of iron(III) cations with a 3+ charge, as well as of oxide anions with a 2- charge, this means we may represent it as Fe_2O_3, which is also a solid material at standard conditions;
  • tetraphosphorus decoxide consists of 4 phosphorus atoms and 10 oxygen atoms, as stated by the prefixes, this is also a solid;
  • iron metal is simply 'Fe'.

Putting all of this into a single equation and balancing it, we obtain:

12~P (s) + 10~Fe_2O_3 (s)\rightarrow 3~P_4O_{10} (s) + 20~Fe (s)
