50 ml of water is poured into a beaker. 50 ml of another liquid is poured into the same beaker. the beaker is left undisturbed for some time. after some time, it is observed that the liquid forms a clear layer on top of water. if the density of water is 1 g/cc, what could be the density of the second liquid? a) 0.8 g/cc b) 1 g/cc c) 1.8 g/cc d) 1.12 g/cc

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature

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?

If we compare and contrast electromagnetic waves with sound waves, all but one statement is true. that is a) sound waves require a medium to travel while electromagnetic waves do not. b) electromagnetic waves can travel through the vacuum of space while sound waves cannot. c) electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere. eliminate d) sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
