The freezing point of a CaCl2 solution is -24 °C.
1.What is the molality (m) of the CaCl2 solution?
2.What is the boiling point of the CaCl2 solution?
Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written:
3.What volume of 1.75 M HCl in liters is needed to react completely (with nothing left over) with 0.250 L of 0.500 M Na2CO3?
4.A 501-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 12.1 g CO2. What was the concentration of the HCl solution?
What is the electron configuration for Cr3+. Also, I need explanation as to how the d orbital works. Why does it go from 4s2 to 3d
Trimyristin and myristic acid have similar melting points. based on melting point measurements only, how could one know that the product isolated at the end of this experiment is truly myristic acid and not unreacted trimyristin
Calculate: A) mL of NaOH needed to reach the equivalence point B) pH of the solution before the addition of any NaOH C) pH of the solution after the addition of 15.0 mL of NaOH
When you think about things that you encounter in daily life - there are many examples of limiting reactants.
If in a distillation apparatus does the water enter the condenser at the hose connection closer to the receiving flask or closer to the reaction pot. Define why it is important that it be this way.
Lead(II) forms soluble hydroxo complexes in excess base. Calculate the molar solubility of lead hydroxide (yellow form) at pH 8.46. See your text for equilibrium constants.
How much heat is evolved when 265 g of ammonia gas condenses to a liquid at its boiling point
what mass in grams of lead(II) Iodide is formed, assuming the reaction goes to completion? b) What is the molarity of Pb2+ in the resulting Solution?
Locate a case where acid rain has adversely affected a lake in either Vermont or New Hampshire.
Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide:
what is the activation energy of a reaction if its rate constant at 35 c was double the value of the rate constant at
