Elemental analysis Measurements show that unknown compound X has the following composition:
element mass %
carbon 18.1%
hydrogen 2.27%
chlorine 79.8%
Write the empirical chemical formula of X

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.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

i think its 100

i hope this !
