What net ionic equation describes the reaction when these solutions are mixed?
GarryVolchara [31]
Balanced chemical reaction:
2Na₃PO₄(aq) + 3CaCl₂(aq) → 6NaCl(aq) + Ca₃(PO₄)₂(s).
Ionic reaction:
6Na⁺(aq) + 2PO₄³⁻(aq) + 3Ca²⁺(aq) + 6Cl⁻(aq) → 6Na⁺(aq) + 6Cl⁻(aq) + Ca₃(PO₄)₂(s).
Net ionic reaction: 2PO₄³⁻(aq) + 3Ca²⁺(aq) → Ca₃(PO₄)₂(s).
<span>(aq) means that substances are dissociated on cations and anions in water.
</span>(s) means solid.

Baking soda, NaHCO3, can be commercially produced during a series of chemical reactions called the Solvay process. In this proce
Mnenie [13.5K]

Answer:

CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)

Explanation:

The solvay process is an important process in the chemical industry. In this process, ammonia gas is first dissolved in concentrated brine to form a mixture known as ammoniacal brine. This solution is made to trickle down the tower. A counter stream of carbon dioxide is forced up the tower. The two substances react to form sodium hydrogen trioxocarbonate IV. This substance is only slightly soluble and separates out as a solid sludge. The product is now dried and heated to give sodium trioxocarbonate IV.

The overall reaction of the process can be given as;

CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)

Calcium chloride is merely a by-product.

identify the correct practices when setting up the condenser for a reflux system. select one or more:
erastovalidia [21]

The correct practices when setting up the condenser for a reflux system are option(c)and (d)i.e, to Grease the joint between the flask and the condenser and Align the flask so that the condenser is vertical.

A condenser's purpose is to transfer heat from a working fluid—in a steam power plant, for instance, water—to a secondary fluid or the ambient air. The effective heat transfer that takes place during phase shifts, in this case during the condensation of vapor into a liquid, is what powers the condenser.

A condenser is a heat exchanger used in heat transfer systems to cool a gaseous substance so that it condenses into a liquid condition. By doing this, the substance releases its latent heat and transfers it to the environment. On the back of a refrigerator, the condenser is located and is probably pretty dusty. The refrigerant cools down within and condenses, changing back from a gas to a liquid.
