Anew element -- quickly named reachium by the scientific community -- is discovered. this element is found to have
two isotopes. 86.4% of all reachium atoms are reachium-328 and 13.6% are reachium-333. what is the atomic mass of
this element?

Un cierto gas tiene un volumen de 800ml a 80°c y 600ml a 80°c y 600mmhg de presión. ¿cual será el volumen del gas a condiciones normales? sí el gas es oxígeno, ¿cuál será su peso? y ¿cuántas moléculas están presentes en el sistema?

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.

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
