Answer: Shameeka's error was: the individual calcium atoms become ions with a negative 2 charge
Explanation: when calcium donate two electrons, it will become positively charged i.e Ca^2+
B. compound, a compound is when two or more atoms chemically fuse. Hope that helped :)!!
Answer:
A molecule of the kind normally found in living systems.
Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen.

Linear molecule with two domains
Explanation:
The describe geometry of the substance fits that of a linear molecule with two domains.
This description is based on the VSEPR i.e Valence Shell Electron Pair repulsion(VSEPR) model. It states that if an atom is bonded by two or more kinds of atoms the shape is determined by the geometry of the bonds around the central atom.
The electron domain is the number of lone pairs of electron around an atom.
Here in CO₂:
there are two lone pairs and the oxygen atoms are in a 180° linear shape around the central carbon atom. The bond is made up of two O⇔C structure.
