Step 4: Model the energy change in the reaction. a) Create an energy graph that illustrates the energy change in the reaction.

b) Construct your graph on a blank sheet of paper. Be sure to label the axes, provide a title, and identify the reactants and products on the graph.

3) in peaches, [oh]=3.16x10-11 m a) find [h+ ] b) what is the ph? c) is the solution acidic, basic, or neutral?

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. p k a1 p k a2 1.30 6.70 calculate the ph for each of the points in the titration of 50.0 ml of 1.5 m h3po3(aq) 1.5 m h 3 po 3 ( aq ) with 1.5 m koh(aq). 1.5 m koh ( aq ) .

The arrangement of particles is most ordered in a sample of
