Problem- Calculate the number of molecules in a deep breath of air whose volume is 2.30L at body temperature, 37?C, and a pressure of 735torr.
I am in urgent need of solution of above problem with complete explanation
Place drying tube filled with CaCl2 on condenser. Heat to reflux at 190 C for 25 minutes then cool. Add 0.5mL tolulene and petroleum ether 0.5-0.75 mL until slight cloudiness remains. Reheat until clear and cool in ice bath. Collect product and wa..
Aerosol cans have a label that warns the user not to use them above a certain temperature and not to dispose of them by incineration. Even an empty can contains residual gaseous propellant.
1-methylcyclohexene and 3-metheylcyclohexene were mentioned as possible products were mentioned as possible products of the dehydration of 2-methylcyclohexanol. Why wasn't 2-methylcyclohexene mentioned as a possible product
The Ka of HNO2 is 7.1 x 10^-4. Use this to find the volume (mL) and pH of 0.0588 M KOH needed to reach the equivalence point(s) in titrations of 28.5 mL of 0.0380 M HNO2.
What property of the atom did Moseley associate with the wavelength of X-rays emitted from an element in his experiments?
Question- For each of the following reaction conditions decide if they would preferentially lead to E1 or E2 reactions.
How many ml of a 0.050 M kMno4 solution are required to oxidize 2.00 g of feso4 in a dilute solution
State balanced chemical equation showing how each of these compounds dissolves in water as well as with the charges on top for each one of them.
two mwthods were described for determining the volume of the flask used for the molar mass determination.
When 200ml of 0.11M hydrochloric acid (HCl) is mixed with 800ml of 0.10M methylamine (CH3NH2), write the net ionic reaction that favors products and occurs as the solutions are mixed. Then write the equilibrium reaction that you would use to solve..
