Question

1. apply concepts two chemists each plan an investigation in which they will combine hydrogen gas with chlorine gas to observe the chemical reactivity. the plans differ in that one will use 25 milligrams each of hydrogen and chlorine, and the other will use 1000 times this amount, i.e., 25 grams each of hydrogen and chlorine. can the investigations reach similar conclusions about the reactivity of hydrogen with chlorine? explain.

Explanation:

Chemical reactivity is an intensive property not dependent on the amount of substance. As long as the reaction conditions like temperature, pressure etc. are the same, the reactivity behavior of hydrogen and chlorine will be consistent regardless of the mass used (25 mg or 25 g).

Answer:

Yes, the investigations can reach similar conclusions about the reactivity of hydrogen with chlorine because chemical reactivity is an intensive property and does not depend on the quantity of the substances as long as reaction - conditions are constant.
