Mass transfer - humid air is at 40ºc with 20% relative humidity. a.) what is the wet bulb temperature? b.) if the air is in a 5 l flask and cooled until it condenses, what temperature does condensation occur? c.) what is the mass of dry air, water, and humid air in the flask? d.) what is the enthalpy change for this cooling (in j)? e.) if the flask was cooled further, to 4ºc, what fraction of the water in the humid air will condense?

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
