If a bottle of nail polish remover contains 177 ml of acetone, how much heat would be released by its complete combustion? The density of acetone is .788 g/ml
Organic chemistry mechanism and conceptual problems involving, Write equations to show how nitronium ions might be formed using a mixture of nitric and sulfuric acids.
A buffer, consisting of H2PO4- and HPO42-, helps control the pH of physiological fluids. Many carbonated soft drinks also use this buffer system.
Calcium carbide, CaC2, reacts with water to form acetylene. CaC2(s) + 2 H2O(l) C2H2(g) + Ca(OH)2(s) How many grams of water are needed to react with 473 g of calcium carbide?
An excess of aluminum foil is allowed to react with 225 mL of an aqueous solution of HCl (d = 1.088 g/mL) that contains 18.0% HCl by mass.
(the freezing point constant is 1.86 C/m). On the basis of these data, one can conclude that the nonelectrolyte has a molecular weight of?
A vitamin C capsule is analyzed by tirating with 0.3M NaOH. It is found that 24.4 ml of base is required to react with a capsule weighing 0.55g.
What mass of NaOH is needed to precipitate the Cd^{2+} ions from 39.0 mL of 0.550 M Cd(NO3)2 solution?
How would you go about finding how many mL of 2.00 molar NaOH (Aqueous) solution are required to neutralize 1.858 g of KHC8H4O4 (it's formula weight being 204.22)? Any other example would do
Let's say that you are given a 0.215g of unknown weak acid and asked to dilute with 75 mL of DI water. You then use a standardized 0.125 M NaOH to titrate the unknown acid solution
Values of the rate constant for the decomposition of N2O5 at four different temperatures are as follows: Determine the activation energy (I got this step right, Ea = 101.15 kJ/mole)
how much energy (MJ) can be obtained from incineration and how much CO2 (kg/year) may be released in that year? 2) How much of that energy (MJ) can be actually converted into electric power if the conversion efficiency is 23%?
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.
