Answer:</h3>
Ba(NO₃)₂(aq) + CuSO₄(aq) ⟶ BaSO₄(s) + CU(NO₃)₂(aq)
2K₃PO₄(aq) + 3MgCl₂(aq) ⟶ 6KCl(aq) + Mg₃(PO₄)₂(s)
<h3>
Explanation:</h3>
- Precipitation reactions are types of reactions that involve a reaction between soluble salts to form an insoluble salt or a precipitate and a soluble salt.
- The equations given in the question are examples of precipitation reactions that lead to the formation of precipitates BaSO₄ and Mg₃(PO₄)₂
- The balanced equations are;
Ba(NO₃)₂(aq) + CuSO₄(aq) ⟶ BaSO₄(s) + CU(NO₃)₂(aq)
2K₃PO₄(aq) + 3MgCl₂(aq) ⟶ 6KCl(aq) + Mg₃(PO₄)₂(s)
- Based on solubility rules, all sulfates are soluble except CaSO₄, BaSO₄, PbSO₄ and silver sulfate. Therefore, BaSO₄ is a precipitate and will have a solid-state.
- All phosphates are insoluble except those of ammonium, potassium, and sodium. Therefore, Mg₃(PO₄)₂ is a precipitate and will have a soluble state.
Answer:
C: evaporation
Explanation:
this is a liquid to gas, so evaporation matches this scenario
hope this helps! Please give brainiest!!! ty
Its D for the second energy level, but the first energy level is 2.
Evaporation because the salt would dissolve in the water then boil the water and it will evaporate leaving the salt left in the bowl
