Question

explain the following statements with related chemical equations ​

Answer 1

Answer:A balanced chemical equation is an equation where the mass of atoms of the reactants(I.e.on the left side) is equal to the mass of the atoms of the products (I.e. on the right side) Example, here's an unbalanced equation Cu + O2 —> CuO. After balancing, 2Cu+O2–>2CuO.

Answer 2

(a) Skeletal equation: H₂ (g) + N₂(g) →NH₃(g)

Balanced equation: 3H₂ (g)+ N₂(g) →2NH₃(g)

(b) Skeletal equation: H₂S (g) + O₂(g) → H₂O (l) + SO₂(g)

Balanced equation: 2H₂S(g) + 3O₂ (g) → 2H₂O(l) + 2SO₂(g)

(c) Skeletal equation: BaCl₂(aq) + Al₂SO₄(aq) → AlCl₃(aq) + BaSO₄(s)

Balanced equation: 3BaCl₂(aq) + Al₂(SO₄)₃(aq) → 2AlCl₃(aq) + 3BaSO₄(s)

(d) Skeletal equation: K(s) + H₂O(l) → KOH(aq) + H₂(g)

Balanced equation: 2K(s) + 2H₂O(l) → 2KOH(aq) + H₂(g)
