Answer:
chemical change
Explanation:
electrolysis process by which electric current is passed through a substance to effect a chemical change.
Answer:
- The name for the potassium oxide's structure is ionic.
Properties:
- High melting point.
- Soluble in water.
Explanation:
- The ionic structure it is formed by a cation (atom with positive charge) and an anion (atom with negative charge). In this case, potassium is the cation and the oxigen is the anion.
- Since potassium oxide is an ionic compound, it has a high melting point, because of the strong bonds. Also, it is soluble in polar solvents, like water, because its ions generate polarity in the molecule.
The answer would be 425.599 because 1 ATM is 760 mmHg.
The answer is B, Let me know if you get it right!
Agitation, or stirring of the solute in the solvent increases the solubility of the solution
