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⁻]

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
