When calculating the AH of a reaction, why is it important that you include the correct stale symbols in your balanced chemical
equation?
1 answer:
Answer: c. so that you use the correct energy states
Explanation:
Enthalpy is the energy release or energy produced when a chemical reaction is carried out.
Enthalpy change is calculated by substracting the energy of reactants from the energy of products.
As the energies are different for different states and thus the correct stale symbols in your balanced chemical equation must be given so that we use the correct energy values.

Answer:
A beaker
Step-by-step explanation:
Specifically, I would use a 250 mL graduated beaker.
A beaker is appropriate to measure 100 mL of stock solution, because it's easy to pour into itscwide mouth from a large stock bottle.
You don't need precisely 100 mL solution.
If the beaker is graduated, you can easily measure 100 mL of the stock solution.
Even if it isn't graduated, 100 mL is just under half the volume of the beaker, and that should be good enough for your purposes (you will be using more precise measuring tools during the experiment).
