Draw the most stable chair conformation for (1S,3S)-1-chloro-3-ethylcyclohexane. Please explain your answer.
A 75.0-mL volume of 0.200 NH3 is titrated with 0.500 M HNO3 . Calculate the pH after the addition of 19.0 mL of HNO3
The mass spectrum of an organic compound shows the relative abundance of M to be 34.29% and M+1 to be 8.901%. Assuming the peaks are caused by 12C and 13C isotopes, determine the number of carbon atoms in the compound. Natural abundance: 12C is 98..
When 0.047 moles of ammonium sulfate are dissolved in enough water to make 413 milliliters of solution, how many ammonium ions are present?
Determine the amount of heat (in kJ) given off when 1.89 104 g of ammonia are produced according to the following equation. Assume that the reaction takes place under standard-state conditions at 25.0°C.
