Saponification, salt of fatty acids are created, glycerol as well.
Answer:
sodium chloride—is NaCl.
Explanation:
Table salt is an ionic compound, which breaks into its component ions or dissociates in water. These ions are Na+ and Cl-. The sodium and chlorine atoms are present in equal amounts (1:1 ratio), arranged to form a cubic crystal lattice.
Answer:
The answer to your question is: 55.84 u. The element is Iron
Explanation:
isotope 1 mass 53.94 u abundance 5.85%
2 mass 55.9349 abundance 91.75%
3 mass 56.9354 abundance 2.12%
4 mass 57.9333 abundance 0.28%
average atomic mass = (53.94 x 0.0585) + (55.9349 x 0.9175) + (56.9354 x 0.0212) + (57.9333 x 0.0028)
average atomic mass = 3.155 + 51.32 + 1.207 + 0.1622
average atomic mass = 55.84 u. The element is Iron
Protons and electrons.
Side note: Neutron numbers may vary due to existence of istopes ((molecules that have the same number of protons (therefore its the same element) but different number of protons))
