The earliest idea of the atom is that it is made up of tiny, invisible particles, called the atoms, is believed to have originated from the Greek philosopher Leucippus of Miletus and his student, Democritus of Abdera, around 5th century B.C. However, it wasn't until centuries later that the atomic theory was taken seriously by the society, thanks to the scientist John Dalton by 1808. Hence, the development of the Atomic Theory began until the modern age. Modern scientist has more technological advancements than the early age. Therefore, the modern scientist can view the atom more detailed than before.

The type of rock that develops from molten rock cooling above the Earth’s surface is the Igneous rock.
When hydrogen atoms are energized by electricity, an emission spectrum of specific colors occurs because of the different wavelengths.
Answer:
2KClO3(s) + heat → 2KCl(s) + 3O2(g)
Explanation:
KClO3(s) + heat → KCl(s) + O2(g)
Adding coefficients so that there are 6 O atoms on both sides.
2KClO3(s) + heat → KCl(s) + 3O2(g)
Balancing K and Cl atoms, there are 2 of each on the left and 1 of each on the right.
2KClO3(s) + heat → 2KCl(s) + 3O2(g)
The equation is now balanced.
