Answer:
electron configuration
Explanation:
The arrangement of electrons in the atomic orbitals of an atom is called the electron configuration. Electron configurations can be determined using a periodic table.
Answer:
Explanation:
Hello,
In this case, we could considering this as a redox titration:
Thus, the balance turns out (by adding both hydrogen ions and water):
Thus, by stoichiometry, the grams of Fe+2 ions result:
Finally, the mass percent is:
Best regards.
Hi,
The answer is HF since hydrogen bonds are can be formed only between Hydrogen and Fluorine, Oxygen or Nitrogen.
To test for hydrogen, burn a candle near the suspected source of hydrogen. If you hear a squeaky pop sound, hydrogen is present because when hydrogen gas burns, it makes a squeaky pop sound.
