a compound is composed of the elements c, h, o, and cl. combustion analysis of a 3.06 g sample of the compound produced 3.43 g of carbon dioxide and 1.05 g of water. in a separate experiment reaction of a 2.71 g sample of the compound with excess lead produced 4.80 g of pbcl2. what is the empirical formula of the compound

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
