In the isothermal reversible compression of 52.0 mmol of an ideal gas at 260 K, the volume of the gas is reduced from 300 mL to 100 mL. Calculate w for this process.
A solution of 120 mL of 0.150 M KOH is mixed with a solution of 260 mL of 0.200 M NiSO4. How many grams of the precipitate can be formed?
if you have water of 330 ml at 25 degrees and then combine water of 130 ml at 95 degrees celsius temperature then
a experiment would also work using another reactive metal such as zinc.If you had used the same number of grams of Zn as you did Al in this experiment,would you have obtained more or less hydrogen. Illustrate with an equation and calculation
Fluorine-18, which has a half-life of 110 min, is used in PET scans. (see section 4.5.) If 100 mg of fluorine-18 is shipped at 8 A.M., how many milligrams of the radioisotope are still active if the sample arrives at the radiology laboratory at 1:..
A 62g piece of ice at 0 degrees C is added to a sample of water at 6 degrees C. All of the ice melts and the temp of water decreases to 0 degrees C. How many grams of water were in the sample?
The element cesium (Cs) freezes at 28.4 degree celsius, and its molar enthalpy of fusion is delta H fusion =2.09kJ/mol. a.) when molten cesium solidifies to Cs (s) at its normal melting point, is delta S positive or negative? b.)calculate the valu..
what is the molarity of a solution prepared by adding 132 grams potassium chloride to enough water
Draw the two possible products of the reaction between benzaldehyde and ethylpropylketone
When 50.0 mL of a 0.3000 M AgNO3 solution is added to 50 mL of a solution of MgCl2, and AgCl precipitate forms immediately. The precipitate is then filtered from the solution, dried, and weighed.
