Isotonic Saline solutions, needed for many medical applications, contain 0.9% (mass/volume) salt. a typical IV bag can hold 1.00 L of solution what mass of salt is required to prepare 1.00 lL of isotonic saline solution?

Balance this equation: n2 + h2 > nh3, write the following molar ratios: n2 / n2 / nh3 h2 /

How many moles of no2 will form when 3.3 moles of cu are reacted with excess hno3?

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
