I am given a question that gas a certain number of moles of CO3 2-, and a certain number of moles of Ca 2+, and a certain number of CaCO3(solid) moles. If this solution is not at equilibrium, then what kind of reaction will occur ? Would I need to calculate this depending on the concentrations given ?

Answer #1

Calcium carbonate is sparingly soluble in water. The solubility equilibrium is as shown.

The expression for the solubility product is

Since, the number of moles of calcium ions and carbonate ions are given, the value of the solubility product can be calculated.

If the solubility product is given and the number of moles of either calcium ions or carbonate ions are given, the number of moles of carbonate ion or calcium ion can be calculated.

For these calculations the volume must be given or molar concentrations should be given.

0.75 moles of O2 gas is mixed with 0.45 moles of N2 gas in a 2.5 L tank at 1970 K. The two gases react to form NO gas and the system is allowed to react equillibrium. The equillibrium constant for this reaction is equal to 4.14 x 10-4. What are the quillibrium concentrations of all three components? I would really apreciate help with this question. thank you!

Limestone (CaCO3) can be broken down at high temperatures: When heated at 1.00x103 K for a certain amount of time, it can be completely transformed into two oxides: carbon dioxide and calcium oxide (known as “burnt lime”, figure why J). The solid is then completely dissolved in enough water to form a concentrated solution of Ca(OH)2. A 750-fold diluted solution of Ca(OH)2 required 50.0mL of a HCl 0.200M solution to completely neutralise its Ca(OH)2 content. a) How many moles of...

I am unsure how to solve this question. The flow rate and NaCl concentration of a river are 2 million gallon per day and 32 ppm. A food processing plant produces and releases a saline solution at a rate of 85 gpm into the stream. The salts quickly become uniformly distributed in the stream. Downstream of the discharge point is a fishing spot. Because the fish cannot tolerate the salt concentrations above 200 mg/L, the NaCl concentration of effluent must...
