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.
I believe the answer would be A. A pea is to a pod
Mass = moles x molar mass
so mass of 6 moles of h2 is: 6×1×2 = 12g
The correct answer is: [B]:

B. carbon-13 is not an allotrope of Carbon.
Allotropes<span> are elements on the periodic table that have more than one crystalline form. </span>Isotopes<span> are atoms of the same element with the same atomic number but have a different mass number.
C-13 is an isotope of carbon, not an allotrope.</span>
