Draw all the structural isomers for the molecular formula C4H9Br. Be careful not to draw any structures by crossing one line over another; the system needs to know where you intend connections to be between atoms.
Glucose Isomers, When glucose is placed in water two stereoisomers are formed, one with the new OH on the opposite side of the ring than the 6th carbon
How many moles of each of the following were in the original sample? What is the molecular formula?
the fraction of the initial mass of gas remaining in the tank if carbon dioxide obeys the ideal gas and PR equations of state
Define detection limit. Does a compound with high molar absorptivity have a higher or lower limit of detection than a compound with low molar absorptivity
milk is pasteurised when heated to 63 C for 30 minutes, but if it is heated to 74 C it takes only 15 seconds for the same result. Find the activation energy for this sterilisation process
The gaseous product of a reaction is collected in a 25.0 L contained at 27 degrees Celsius. The pressure in the container is 216 kPa, and the gas has a mass of 96.0g. What is the molar mass of the gas?
The first-order rate constant for the decomposition of N2O5, 2N2O5 --> 4NO2 + O2 at 70 degrees C is 6.82 * 10 ^-3 . Suppose we start with 2.90×10?2 of in a volume of 1.7 L. A)
What mass of natural gas (CH4) must burn to emit 470. kJ of heat? CH4(g) + 2 O2(g) CO2(g) + 2 H2O(g).
A reaction between methane and hydrogen sulfide to produce carbon disulfide and hydrogen gas was carried out. CH4 (g) + 2 H2S(g) → CS2 (g) + 4 H2 (g)
