Nitrous oxide gas is used by some denatl practitioners as a anesthetic. Nitrous oxide can be produced in small quantities in the laboratory by cardful heating of ammonium nitrate. Write the unbalanced chemical equation for the reaction.
36.45 mL of 0.11 M hydrochloric acid were added to 36.45 mL of 0.098 M aqueous barium hydroxide. Calculate the theoretical yield of the salt produced.
1. the equation for a beers law plot is y 2012.5x 0.003. if the recorded absorbance for an equilibrium mixture is
You may use expanded, condensed, or line structures, provided they are neat and legible. If you could not identify one of your components, then pick an appropriate component from the list of unknowns.
1. compute the henrys law constant of air if the solubility of air in h2o is approximately 2.1 x 10-3 m at the
Assuming no elasticity forces in rubber, what volume should a 1.0L ballookn at 25 degree Celsius and 1.00 atm pressure be if immerses in liquid nitrogen
What volume (mL) of hydrogen gas, saturated with water vapor, will be obtained from a 0.1138 gram sample of alloy which is 73.2% aluminum? (Pbar= 754.3 torr, Temp= 21.2 Celsius)
Imagine that you have a 5.50 gas tank and a 4.00 gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
What is the pH of the solution resulting from the addition of 25.0 mL of .01M NaOH solution to 40.0 mL of .01M acetic acid
Neat, aliphatic, primary amines show two absorptions between 3400 to 3330 cm-1 and 3330 to 3250 cm-1 due respectively to asymmetrical and symmetrical stretch. Stretch at 3300 cm-1. Why do tertiary amines not absorb in this region of the spectrum?
a sample of a solid of 29.19 grams is placed in a flask. toluene is added to the flask toluene in which the solid is
Methyl Orange is an acid-base indicator. In dilute solution, at pH greater than 4.4, it is yellow. At pH=3.2 the solution appears red. Draw a structure of the species that is formed at the lower pH of the acid proton adds to the azo nitrogen atom ..
The lower flammability limit (LFL) for a gas is the minimum concentration of the gas, in air, below which there is too little fuel to support combustion.
