Answer:
AuCl
Explanation:
Given parameters:
Mass of Gold = 2.6444g
Mass of Chlorine = 0.476g
Unknown:
Empirical formula = ?
Solution:
Empirical formula is the simplest formula of a compound. Here is the way of determining this formula.
Elements Au Cl
Mass 2.6444 0.476
Molar mass 197 35.5
Number of moles 2.6444/197 0.476/35.5
0.013 0.013
Divide by the
smallest 0.013/0.013 0.013/0.013
1 1
The empirical formula of the compound is AuCl

Explanation:
Answer:
The Answer is B: subtract atomic mass from atomic number. I remember doing this in 8th grade!!!:)
Explanation:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom and the atomic number.
Due to a difference in electronegativity between the two atoms. The atom with more electronegativity will attract the electrons to itself more than one with a lower electronegativity which will create a slight negative charge around the more electronegative. I hope this helps. Let me know if anything is unclear.
