At -11.0 °C (a common temperature for household freezers), what is the maximum mass of sorbitol (C6H14O6) you can add to 2.50 kg of pure water and still have the solution freeze? Assume that sorbitol is a molecular solid and does not ionize when it dissolves in water.
What volume (mL) of 0.663M potassium hydroxide aqueous solution is needed to neutralize [?this means to completely react with] 842 mL of 0.554M nitric acid?
What mass of CCl4 will be formed if 1.20 moles of methane react with 1.55 moles of chlorine?
Calculate the calorimeter constant. The enthalpy of combustion of antracene is -7061 kJ/mol.
If the primary alcohol ethanol is subjected to sulfuric acid, an SN2 substitution would occur instead and diethyl ether would be formed.
the pH of the solution is 9.15. After adding 16.55 mL of hydrochloric acid to your sample, the pH is 8.78. Calculate the first derivative of the function of the pH of your solution with respect to the volume of titrant added
Calculating standard enthalpy change, heat, and mass of a reaction, Methanol (CH3OH) is used as fuel in race cars. Calculate the standard enthalpy change for the reaction, assuming H2O(g) as a product.
what is an example of a hypothesis testing for the percentage of ethanoic acid in vinegar? Give me examples of hypotheses and how to test them. thanks :)
Predict what would appear in the solution if NAOH has been added to the CuSO4 solution instead of the NH3.
Calculate the volume of 1.70 m Na3104 in milliliters that contains 3.00 g of solute.
A solution contains 15mL 0.1 M KI, 15 mL of DI water and 5 mL o f3% H2O2. After the decomposition of H2O2 is complete, you titrate the solution with 0.1 M AgNO3. If the catalyst, I-, is not consumed in the reaction and is completely recovered, wha..
