Calculate the weight of benzene codistilled with each gram of water and the percentage composition of the vapor produced during a steam distillation. The boiling point of the mixture is 69.4°C is 227.7 mmHg.
Name the alkene(s) with the molecular formula C6H12 that are unbranched and that show E/Z isomerism.
Consider an electron moving from left to right (toward positive x) in a constant potential of V = 2.0 eV with total energy, E = 5.0 eV. Let the electron be described as a free particle such that the constant potential DOES NOT depend on the spatia..
A 350.0 mL sample of oxygen gas was collected over water at a temperature of 25.0ºC and 740.0 mm Hg. How many moles of gas were there in this sample if the vapor pressure of water at 25.0ºC is 23.8 mm Hg?
where the temperature and pressure are 4oC and 3.0 atm, to the water's surface, where the temperature is 25oC and pressure is 0.95 atm. Calculate the final volume of the bubble if its initial volume was 2.1 mL
Distilled water in the same tube gave a reading of +0.016 degrees. Calculate the specific rotation for the compound.
Compute the number of mL of 2.00M H2SO4 required neutralizing 125.5mL of 1.2M KOH
if 9.0L of NO are reacted with excess O2 at STP, what is the volume in liters of the NO2 produced?
The initial volume of the balloon is 5.00 , and the pressure is 760. The balloon ascends to an altitude of 20, where the pressure is 76.0 and the temperature is 50. What is the new volume, of the balloon in liters, assuming it doesn't break or leak
Keep in mind that it will be too thick and greasy to insert in a capillary tube. Also, remember that the melting point of vegetable oil is well below room temperature.
Consider the hypothetical elements A, B, and C and assume these elements react to form several different binary covalent compounds. Two of the compounds are A2B2 and B3C.
We often hear the terms organic, natural, and chemical in the media. Organic and natural are usually used to imply that a product is "healthy" and/or "environmentally friendly" while chemical often implies negative implications for health and for ..
One of the chair conformations of cis-1,3-dimethylcyclohexane is more stable than the other by 23.1 kJ/mol. Use this to estimate the energy cost of a 1,3-diaxial interaction between two methyl groups
