AP Chem HW help!
Conditions around hydrothermal vents deep in the ocean floor can enable chemical reactions that produce solid materials. A student models one of these reactions by combining aqueous Ca(OH)2 and Na2SO4, and observes the formation of a solid in a liquid.
A. Justify the choice of a net ionic equation for describing this reaction.
B . Write and balance a net ionic equation for the reaction. Show your original equation as well as the balanced one.
C. Explain any changes you made to balance the equation.
