Based on your observations of the laboratory assignment(s) that produced gases, can you conclude that the same gas was produced in each assignment? Briefly explain.

With the use of same chemicals, same gas will be produced while the use of different chemicals, different gases will be produced.

Explanation:

The same gas was produced in each assignment if the same chemicals are mixed with each other while different gases were produced in each assignment when different chemicals are allowed to mix. If every time, same chemicals and same concentration of chemicals are mixed together, the result will be the same means production of same gas but if different chemicals are allowed to mix, then the product will be the production of different gases.

what are the two models

explanation:

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.
