A 21.496 g sample of magnesium is burned in air to form magnesium oxide and magnesium nitride. when the products are treated with water, 2.813 g of gaseous ammonia are generated.
Draw and name the molecule which contains only carbon and hydrgen atoms only three of which are carbon
How many moles of I2 were used in the titration? How many moles of SO2 were in the 5.00 mL sample of wine? Determine the mass of SO2 (in mg) in the 5.00 mL sample of wine. Determine the concentration of SO2 (in mg/L) in the wine.
For the cyclohexanes substituted in the positions indicated, identify the substituents as either axial or equatorial in chair conformers. For example, a 1,2-cis relationship means that one substituent must be axial and one equatorial.
Determine how much PV work is done if 80.0 g of C 2 H 4 and 125 grams of hydro chloric acid are permissible to react at atmospheric pressure and the volume change = -63.9 L? express your answer in kilojoules
Find out the molar mass of each of the given gases 1) 2.16 grams of a gas that occupies 1.38L at 665 mmHg
A 45.0-L steel tank at 20.0°C contains acetylene gas, C2H2, at a pressure of 1.39 atm. Assuming ideal behavior, how many grams of acetylene are in the tank?
Iron(III) is polarographically reduced to iron(II)at potentials more negative than about +0.4V versus SCE and is further reduced to iron(O) at -1.5V (vs SCE). Iron(II) is also reduced to metal at -1.5V.
A gas expands and does P-V work on the surroundings equal to 328 J. At the same time, it absorbs 108 J of heat from the surroundings. Calculate the change in energy of the gas.
