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.
Answer:
this is fairly simple if you have a periodic table with you.
Explanation:
atomic number 17 is Cl mass numer is 35.45 for protons neutron and electron you can just look that up on google. atomic number is where it is at on the periodic table and the mass number is in the little square at the bottom.
Answer:
option D
Explanation:
Increasing the temperature increases the yield of ammonia and speeds up the reaction as chemical reaction is affected by temperature.
