A container with a volume of 25.5L holds 1.050mol of oxygen gas (O2), whose molar mass is 31.998g mol. What is the volume if 7.21g of oxygen gas is removed from the container, assuming the pressure and temperature remain constant

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i. e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

Astudent carefully transfers 30 g of water and 30 g of alcohol in a glass tube, forming two layers and filling the tube completely. after sealing the tube, the student mixes the solutions, and notices a bubble that forms in the tube. what is the mass of the contents in the glass tube after mixing?
