A student sets up two reactions. Reaction 1 uses 0.290 of reactant, and Reaction 2 uses 0.580 of reactant. How many times faster is Reaction 2 compared to Reaction 1? Express your answer as a multiple of the rate for Reaction 1 to three significant figures. Note that Reaction 1 is already written for you, so just enter the number.
Determine the molar concentration of Na+ in a solution in which 6.315+/-0.004g of Na3PO4 has been added to 1000.0+/-0.4mL
A pound of coffee beans yields 50 cups of coffee (4 cups = 1 qt). How many milliliters of coffee can be obtained from 5 g of coffee beans?
Until 200 yr ago, manufactured iron contained charcoal produced from freshly cut wood that was added during the smelting process. As a result of this practice, older samples of iron can be dated accurately using the carbon-14 method
You are on a backpacking trip and need to make a fire. You have some batteries and a piece of foil from some gum. These should be sufficient to get the fire going.
Considering the mixture of the two compounds and range of the melting points, the reason recrystallization was difficult was due to a broad melting point range.
A sample of gasoline contains various hydrocarbons, which comprise atoms of carbon, hydrogen, and oxygen. The hydrocarbons mix together uniformly to form gasoline.
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
Find the mass of urea (CH4N2O) needed to prepare 50.8 g of a solution in water in which the mole fraction of urea is 7.55×10?2.
Assume that 50.00ml of 0.100M HCl was added to 125ml of 0.100M sodium acetate. Is the resulting solution a buffer? Why or why not? Calculate the pH of the resulting solution.
Calculate the amount of 6M NaOH required to react completely with 1.51 grams of Methyl Salicylate. How much of the 6M NaOH that you used was in excess of the theoretical amount?
what is the composition of vapor of a pentane-hexane solution that has a vapor pressure of 373 torr at 25 degree celcius? Given is Pure Hexanes and pentanes vapor pressure at 25 degrees celcius. Pentane - 511 torr. Hexane -150 torr.
The temperature after the reaction is 25.23 C. If the density of final solution is 1.02 g/mL, calculate q, if the specific heat of the solution can be assumed to be equivalent to that of water.
