Answer:
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.

When sodium carbonate and magnesium nitrate solutions are combined, a precipitate is created as a result of a double-displacement process. As you balance the chemical equation, make predictions about the reaction's byproducts.
<h3>What occurs when magnesium sulfate and sodium carbonate are combined?</h3>
A solid may form when the solutions of two soluble salts are combined. Salts that are insoluble are created during precipitation processes. When magnesium sulfate and sodium carbonate are combined, magnesium carbonate, an insoluble salt, results.
<h3>What happens when hydrochloric acid and sodium carbonate interact?</h3>
What takes place when sodium carbonate and hydrochloric acid interact? When sodium carbonate is added to hydrochloric acid, a double displacement reaction takes place, resulting in the formation of sodium chloride, water, and carbon dioxide. The sodium carbonate and the two moles of HCl combine to generate carbonic acid.
