Answer:
Na₂SO₄
Explanation:
Barium nitrate, Ba(NO₃)₂ produce precipitate with SO₄²⁻, CO₃²⁻. That means the precipitate could be obtained from Na₂SO₄ and Na₂CO₃.
Also, magnesium nitrate, Mg(NO₃)₂, produce precipitate just with CO₃²⁻. As the unknown solution produce no precipitate, the unknown compound is:
<em>Na₂SO₄</em>
Answer:solid
liquid
gas
supercritical fluid
plasma
superfluidity in liquid helium (that is Bose-Einstein condensate property)
supersolidity in fermionic condensate like the potassium40

Answer:
Metamorphic Rock
Explanation:
Metamorphic rocks are formed because of high heat and pressure . Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock
You might need to take more pictures so we can see all the equations clearly
