Answer:
The presence of hydrogen ions
Explanation:
Nitric acid is formed when hydrogen ions combine with nitrogen oxide ions leading to formation of a strong acid. Wheareas for strong bases the hydroxyl iins must be present, for strong acid, the hydrogen ions contribute to the acidity. Therefore, from the formula of nitric acid, it has hydrogen ions, an indicator of a strong acid.
Heat is energy, that can be transferred to another item, which is “less hot”.
The answer is D. obsidian. Or at least I think it is. Just guessing based off me playing Minecraft 6 years ago haha
Explanation:
Radioactive isotopes are unstable isotopes whose neutron/proton ratio differs from its stability ratio.
- These isotopes will naturally decay and break down on their own.
- A nucleus with neutron/proton ratio combination which is different different from its stability ratio will be unstable and split into one or more other nuclei.
- This is accompanied by the emission of small energetic particles.

a) two water molecules - hydrogen bond
b) amine and carbonyl - hydrogen bond
c) protonated amine and deprotonated carboxylic acid - ionic bond
Explanation:
You may find the diagram of the chemical structures and the interactions in the attached picture.
Hydrogen bonds are formed when hydrogen is between two electronegative elements such as oxygen, nitrogen or fluorine.
Ionic bonds are formed when one element donates electronic charge from their valence electrons to complete the valence shell of other elements in such a way that results two ions with "+" and "-" charges.
