Explain why a mercury-in-glass thermometer with a uniform-bore capillary that is correct at 0 celsius and 100 celsius read 49.9 celsius when the temperature is actually 50 celsius. note the volume of a sample of mercury Vt at celsius temperature t, realtive to the volume Vo at 0 celsius, is given by :-Vt=Vo[1+(0.18182 *10^-3)t+(0.0078*10^-6)t^2]
What is the pH of the solution if [OH-] of an ammonia solution is 1.0 X 10-2M?
At the temperature of twenty five degree celsius when 1.00 g of sulfur is burned at constant pressure in an atmosphere of oxygen to give SO 2 , and 9.28 kJ of heat is liberated. Determine the ΔHfo of SO 2 ?
Using as sample of gas of 12.0 moles are in a tank of 8.00 Litres at the temperature of 22.6 degree celsius. compute the difference in pressure between CH 4 and an ideal gas under these conditions
What amount of energy is required to completely ionize 29.9 grams of carbon atoms in the gas phase (C(g)) if the ionization energy of C(g) is 1086 kJ/mole.
Determine the molarity of a solution formed by dissolving 15.79 grams of CaCl 2 , calcium chloride in 200.grams of H 2 O, water?
Determine What would be the total volume in the graduated cylinder if density of Ag= 10.5 g/mL.?
If 0.088 moles of sulfuric acid is mixed with water to make 411 mililiter of solution, what is the molarity of H+.
Hardness in groundwater is due to the presence of metal ions, primarily Mg2+ and Ca2+. Hardness is generally reported as ppm CaCO3 or mmol/L Ca2+.
What would be the formula for the compound sample If a sample of a compound contains 1.36 mol of nitrogen atoms and 2.72 mol of oxygen atoms?
Sodium methoxide CH3ONa is a weaker base than BuLi or nBuLi butyllithium. Recommend an explanation why it is not surprising to find that a weaker base is sufficient to prepare the Horner-Emmons-Wittig reagent.
