Answer:
firstly ,<u>GREEK PHILOSPHER </u><u>DEMOCRITUS </u>suggested that matter is composed of tiny particles called atom . In the beginning of 19th century <u>JOHN DALTON </u> put forward atomic theory . At the end of 19th century it was considered that atom can not be subdivided .

Explanation:
This problem deals with balancing of chemical equations.
Every chemical equations obey the law of conservation of matter which states that "in chemical reactions, matter is usually conserved and are not produced, they are simply recombined".
Equation of reaction:
BaO₂ + H₂SO₄ ⇒ H₂O₂ + BaSO₄
Let us use a mathematical approach to balance this equation by setting up simple algebraic equations:
aBaO₂ + bH₂SO₄ ⇒ cH₂O₂ + dBaSO₄
a, b, c and d are the number of moles that will balance the equation;
Conserving Ba: a = d
O: 2a + 4b = 2c + 4d
H: 2b = 2c
S: b = d
now let a = 1
d = 1
b = 1
c = 1
we see that the equation is already balanced
