Solid, liquid, and gas of the same substance have different specific heat values. If 5.00 grams of this substance in the liquid phase has a specific heat value of 2.17 J/g ºC, how much energy would this need to raise the temperature from 15 ºC to 105 ºC?

If 200.0g of copper(ll) sulfate react with an excess of zinc metal, what is the theoretical yield of copper

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.
