Draw the two geometric isomers of 1,3-dibromocyclobutane.
The thermite reaction has been used to weld railroad rails, make bombs, and ignite solid rocket fuel. The equation of the reaction is:
Assuming that the solute consists entirely of NaCl (over 90% is), calculate the osmotic pressure of seawater at 20 degrees C
Small helium-neon lasers emit 1.51 mJ/s of light at 634 nm. How many photons does such a laser emit in one minute?
