H2(g)+ Cl2 (g) --> 2HCI(g). H = "-185kj." 2H2(g)+O2(g) --> 2H2O (g). H= "-483.7" kj. calculate angle H for the reaction: 4HCI(g) + O2(g)0. wCI2(g) + 2H2O(g)

b.

the accuracy of the data.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
