Chlorine has two natural isotopes: 37 17Cl and 35 17Cl. Hydrogen reacts with chlorine to form the compound HCl. Would a given amount of hydrogen react with different masses of the two chlorine isotopes? Does this conflict with the law of definite proportion? Why or why not?
Essential Questions: o Stoichiometry - How much substance do I need or do I get Thermochemistry - How much energy do I need or do I get Kinetics - How fast does it go o Thermodynamics - To what extent does it happen Chemical change - the formation of one or more new chemical substances with a distinct composition or a change in the net amounts of some chemical species in a closed system are indications that a chemical process has occurred Reactants - the result of a chemical process, new chemical substances with different chemical compositions When chemical reactions occur in closed environments, the total mass of the system before and after the process remains constant (mass is conserved) Chemical process alw
