By titrating 15 ml of .1008M sodium hydroxide is needed to neutralize a .2053 gram sample of organic monoprotic acid. what is the molar mass of the acid? If the acid is 5.89% H, 70.6% C and 23.5% O by mass calculate the chemical formula
The radioactive decay of a certain sample produced 936 disintegrations per minute. Exactly 3.00 days later, the rate of decay was found to be 511 disintegrations per minute. Calculate the half-life, in days, for the decay of this sample.
Brass has a specific heat capacity of 0.393 Joules/g C. A paperweight weighing 129g is heated to 95.0 C. Then it is added to 44.6g of water in a calorimeter having a temperature
The following reaction is first order with respect to NO and first order with respect to O2, and the rate constant is 5.0 x 104 M-1s-1: 2NO(g) + O2(g) --> N2O4(g)
Calculate the pH at each point listed for the titration of 25.00 mL of 0.1000 M formic acid with 0.1000 M KOH. The points to calculate are Vb = 0.00, 12.50 and 25.00 mL
a 2.00-g sample of white solid was vaporized in a 345-ml vessel. if the vapor has a pressure of 985 mmhg at 158degc
Find for the combustion of naphthalene. The heat capacity of the calorimeter, determined in separate experiment, is.
how many grams of water can be cooled from 33 to 20 by the evaporation of 37 of water? the heat of vaporization of
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
what quantity graphed versus time yields a straight line for a zero-order reaction and what is the equation for the half life time. b) identify quantity versus time for a first order reaction and equation for half life.
What is the standard free energy change (kJ) for the following reaction at 499.0 K ? [Note: Answer should be expressed as "xxx.x", or with one sig fig after the decimal
