Calculate the volumetric size of a water molecule in vapor, assuming 1 mole of the vapor occupies 22.4 L, as if the vapor were an ideal gas. Give answer in angstroms, two significant digits. Do not write down units in your answer.
What is an alternative way to draw this molecule? (include the resulting formal charge on the Nitrogen, please)
If the rate increases by a factor of 10 as the temperature increases from 35 °C to 70°C, what is the activation energy for the reaction?
A multivitamin tablet contains 40 milligrams of potassium. How many moles of potassium does each tablet contain?
A gaseous reaction occurs at a constant pressure of 50atm and releases 61.5kJ of heat. Before the reaction, the volume of the system was 7.00L. After the reaction, the volume of the system was 2.60L.
Draw a structural formula of an alkene or alkenes (if more than one) that undergo acid-catalyzed hydration and without rearrangement give 2-methyl-2-butanol as the MAJOR product.
The temperature is increased to 45 degree celcius then determine what is the pressure in the cylinder
