More than 2,000 Years Ago, the Greek philosopher Aristotle suggested a model of the solar system. Aristotle's model was geocentric, or Earth-centered. In the model. the sun, stars, planets revolved around the Earth. In 150 AD an astrologer named Ptolemy began to support Aristotle's geocentric model.
In 1543 AD, an astronomer named Copernicus proposed a heliocentric model of the solar system. In this model, the planets revolve around the sun. Due to the invention of the telescope, the solar system could be explored in more detail. Galileo used the telescope to support Copernicus's theory of the sun being the center of the universe.
In the late 1500's, Kepler developed a law that explained planetary motion. Kepler's law is so accurate we still use them today.

Answer:
Sodium Hydroxide + Sulfuric Acid = Sodium Sulfate + Water
2NaOH + H2SO4 → Na2SO4 + 2H2O
Explanation:
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.
Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
Ionic charges are not yet supported and will be ignored.
Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
Compound states [like (s) (aq) or (g)] are not required.
You can use parenthesis () or brackets [].
