In order to determine whether a bond is ionic or covalent, you need to know whether or not it is completely composed of nonmetal atoms or both metal and nonmetal ions.
Barium is a metal and Oxygen is a nonmetal, therefore there is no possible way they could bond unless they were attracted to opposite charges. Specifically, only if Barium becomes a cation and Oxygen becomes an anion then could they bond.
Now cation and anion both have the word "ion" in them, so therefore it must be an ionic bond.
Now we need to know the definition of a bond. A bond is formed when two elements are joined together by sharing their valence electrons.
Therefore, your answer should be:
Ionic, because valence electrons are shared.
B.
I think this is right.
If it is not I apologize
Answer:
Neutralization is when the pH (power of hydrogen ions) of a solution is at 7 (considered neutral in the pH scale). This means it's neither acidic nor basic and is neutral. In order to neutralize an acidic solution, you pour in the same amount of a strong base. And in order to neutralize a basic solution, you pour in the same amount of a strong base.
A neutralization reaction will give you salt and water. A common neutralization reaction could be:
HCl (strong acid) + NaOH (strong base) ----> NaCl (Salt) + H2O (water)
Answer:
well tbh it's just the microwave doing its job heating up your Mac n cheese. But while doing so the Mac n cheese absorbs a lot of heat and then releases it by popping.
