in water which combine to form water molecules.
As the salt formed is , the acid must contain
and thus the acid is
The balanced chemical reaction is ;
The formula of the acid that was neutralized is
1. The atomic number is equal to the number of protons in the nucleus, and the mass number is equal to the number of protons and neutros in the nucleus.
Therefore, to find the number of neutrons we must do mass number - atomic number, which equals 54.
Answer 1: a. 54
2. Atoms of a same element that have a different number of neutrons in the nucleus are called isotopes of an element.
Answer 2: d. Isotopes
3. Potassium has an electron configuration of , meaning that the first 3 shells are full, and that the last shell (4th one) has only 1 electron.
Answer 3: c. Shells 1, 2 and 3 are full and shell 4 has one electron.
4. An atomic bond isn't a specific bond, it's just a term. Polar covalent and non-polar covalent bonds are strong bonds, which leaves us with the hydrogen bonds, which are indeed the weakest bonds out there.
