A 100.0 mL of acetic acid solution of unknown molarity is titrated with 0.15 M NaOH solution. The titration requires 43.25 mL of the base. Determine the molarity of the acid, CH3COOH.
What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
How many grams of sulfur (S) are needed to react completely with 355g of mercury (Hg) to form HgS?
A solution is prepared by adding 5.00 grams of an unkown compound to 217 g of cyclohexane (C6H12). This solution freezes at 4.5 degree C.
Ammonium carbamate (NH2COONH4) is found in the blood and urine of mammals. At a temperature of 424 K, Kc = 0.080 for the following equilibrium:
Heart pacemakers are often powered by lithium-silver chromate "button" batteries. The overall cell reaction is: 2 Li(s) + Ag2CrO4(s) -> Li2CrO4(s) + 2 Ag(s)
Detailed analysis of the 369 and 295 cm-1 bands show them to arise from totally symmetric modes. Show that the Raman spectrum is consistent with a trigonal-bipyrimidal geometry.
A rolled oat's piece has a thickness =1.2 mm. The density= 600 kg/m3, specific heat capacity=2200 J/kgK and thermal conductivity= 0.4 W/mK,The product is to be baked from twenty degree celsius.
A compound has a molar absorptivity of 3.71*10^3 L cm^-1 mol^-1. What concentration of the compound would be required to produce a transmittance
Imagine that you have a 7.00 litre gas tank and a 3.00 litre gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
what will the maximum temperature reached by the resulting solution? [Assume that there is no heat loss to the container, that the specific heat of the final solution is 4.18 J/g*C, and the density of the final solution is that of water.]
A metal bulb is filled with 10.2 g of CHCl3 and 0.322 g of CH4 (two gases). What is the total pressure in the bulb if the temperature is 345 C and the volume is 50.0 mL.
spontaneous chemical reactions produce products which are more energetically stable than the reactants which form them. A strong acid reacts with a strong base to produce water and the free ions of a salt.
