The hardness of the water is given by the presence of calcium and magnesium <span>carbonates. The mixing of these minerals in water turns the water more alkaline.
</span><span>The Langelier saturation index uses the pH to predict the calcium carbonate stability of water. So, through the pH, it is possible to know whether a water is more or less acidic.</span>
Answer:

Answer: The Solar System
Complete Question:
This is the Sun and the celestial objects bound to it by gravity. This includes the eight planets and their 166 known moons,four dwarf planets, and billions of small bodies, including asteroids, comets, meteoroids, and interplanetary dust.
Explanation:
The Solar System is made up of the sun which is a star, the eight planets of which earth is one, smaller planets including Pluto, moons, and hundreds of thousands of other smaller bodies. These smaller bodies include asteroids, comets, meteoroids, and interplanetary dust.
Our solar system is in the Milky Way Galaxy, circling its center at over 500,000 miles per hour. To have an idea of how massive the galaxy is, it takes our solar system, even at this speed, 230 million years to complete an orbit.
