Chemistry: Molarity and Concentrations Determine the concentrations of Na₂CO₃, Na⁺, and CO₃²⁻ in a solution prepared by dissolving 1.31 × 10⁻⁴ g Na₂CO₃ in 2.00 L of water. Express all three concentrations in molarity.

You'll need to determine:

1. [Na₂CO₃]
2. [Na⁺]
3. [CO₃²⁻]

i think its 5049.

i hope this !

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
