Which of the following is best described as a synthesis reaction? (2 points) 2hgo → 2hg + o2 agno3 + nacl → agcl + nano3 hcl + nahco3 → h2o + co2 + nacl 2na + cl2 → 2nacl

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?

Ascience teacher heated liquid ethanol for an experiment. when he turned up the temperature, the ethanol quickly disappeared, and a strong aroma filled the room. what happened to the ethanol?
