Suppose you have 3.5 g of each of the solids in these formula equations - find out the theoretical yield sodium carbonate + Magnesium sulfate Lead(II) nitrate + sodium sulfide Ammonium phosphate + calcium chloride
For 2.25 moles of an ideal gas, Pext=P=200x10^3 Pa. The temperature is changed from 122 C to 28.5C and Cv=3R/2. Calculate the q, w, delta U and delta H for an isochloric process.
50.00g of hot water is mixed with 50.00g of cold water interpolating back to the time of mixing shows that the
Consider a solution that contains 66.0% R isomer and 34.0% S isomer. If the observed specific rotation of the mixture is -30.0°, what is the specific rotation of the pure R isomer
Hydrogen fluoride is a highly reactive gas. It has many industrial uses, but the most familiar property of HF is its ability to react with glass. As a result, HF is used to etch glass and frost the inner surfaces of light bulbs.
Multiple choice questions in nuclear chemistry - which equation represents the balanced nuclear equation
Consider a solution that contains 72.0% R isomer and 28.0% S isomer. If the observed specific rotation of the mixture is -41.0°, what is the specific rotation of the pure R isomer
It's not until death that the percentage of carbon-14 will begin to diminish from decay. Because radioactive decay is a first-order process, the integrated rate law for a first-order reaction can be rewritten asfraction remaining
1) a sample measures 711mmHg pressure at 15 degree C. Later the temperature goes to 45 degree C. What is the new pressure 2) a gas is at 45.2 atm and 51 degree C. what is the pressure at 15 degree C
The value of the Euro is currently $1.32 U.S. and the price of 1 liter of gasoline in France is 0.92 Euro. What is the price of 1 gallon of gasoline in U.S. dollars in France?
Which choice is closest to the longest wavelength that will remove an electron from the n=3 level of the hydrogen atom? (hint: what would you use for the value of nfinal when the electron is completely removed from the atom?)
The density of platinum metal is 21,450 kg/m3. Find the weight in pounds of a cube of platinum that measures exactly 1 inch on each side.
An organic compound is quite polar and is thus much more soluble in methanol than in pentane (bp 36 degree C). Why would methanol
