If this energy were used to vaporize water at 100 ∘c, how much water in liters could be vaporized? assume that the density of water is 1.0 g/ml. the heat of vaporization of water at 100 ∘c is 40.7 kj/mol. (hint: begin by using the enthalpy of vaporization of water to convert between the given number of kilojoules and moles of water.)

The diagram shows the structures of horse and cat forelimbs. what does the diagram suggest about the evolutionary relationship between these two mammals? a. they have homologous structures, indicating a common ancestor. b. they have analogous structures, indicating a common ancestor. c. they have homologous structures, indicating that they do not have a common ancestor. d. they have analogous structures, indicating that they do not have a common ancestor.

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

Which statement correctly identifies the scientific question and describes why the question is scientific? question 1 refers to the supernatural. question 2 reflects a moral or social value. question 3 refers to something that can be measured. question 4 reflects a question that can’t be observed.
