A sample of 30.0 ml of krypton gas, Kr, is at 756 mm Hg and 25.0 degree celsius. What is the new volume if the pressure is decreased to 325 mm Hg and the temperature is decreased to -12.5 degree celsius?
How many kilograms of methane (CH4) are in perfectly insulated piston with the following properties: Volume = 2 cubic meters.
The pressure is changed to 8.75 atm and the gas is cooled to 15 C. Calculate the new volume of the gas using the ideal gas equation.
Give the overall reaction for the dehydration of cyclohexanol.2. IR spectroscopy will be used to verify the isolated compound is the correct compound (cyclohexene). What stretches (presence and absence) will distinguish the product
How many nucleotides are needed to code for a polypeptide with eleven amino acids
Really confused on calculating/finding the half-equivalence point in a titration curve. This was a lab experiment done in my chem lab. We added 0.0750 M NaOH to acetic acid (pipet 10.00mL of ~0.1M HCH3CO2 into the beaker and add 40mL of DI water).
What is the Lewis structure, VSEPR type, molecular geometry, and bond angle for each of the following: NaClO2, KICl4,
