what is the molecular shape of 2-butanol C2H9OH? what are the bond angles, molecular polarity and the hybridization of the bonded atoms? what are the number and type of bonds in this molecule?
The Party Guy, Mr. Balloon, is making animal figures out of long thin balloons that he twists into different shapes. Assume that the balloons are of uniform thickness.
The tank is first evacuated, and then it is connected to a 50.0 L cylinder of compressed nitrogen gas. The gas pressure in the cylinder, originally at 21.5 atm, falls to 1.55 atm without a change in temperature. What is the volume of the tank?
Ammonia reacts with diatomic oxygen to form nitric oxide and watervapor. When 40.0g of ammonia and 50.0 g of oxygen are mixed and allowed to react, which is the limiting reagant? 4NH3 +5O2--> 4NO + 6H2O
The equilibrium constant Kc for the following reaction PCl3(g) + Cl2(g) PCl5(g) equals 49 at 230°C.If 0.70 mol of PCl3 is added to 0.70 mol of Cl2 in a 1.00-L reaction vessel at 230 degrees Celcius, what is the concentration of PCl3 when equilib..
