How Do You Measure the Characteristics of a Chemical Reaction?

[Equilibrium]

Geetings In relation to chemical kinetics i was confused about how I can determine the characteristics/(explanation?) of a chemical reaction?

for example:
$$CaCO_3 + HCl -> CaCl_2 + CO_2 + H_2O?$$

1.)amount of CO_2 heat evolved
2.) change in pH
3.)amount of CO_2 / volume CO_2
4.) Change in concentration of reactants
5.) Change in pressure
6.) change in conductivity

I just don't actually get it...
$$Mg + O_2 -> 2MgO$$
so the answer might be
1.) the amount of mass of Mg?
hmmm

What is the common technique in of determining these observations?

Eq, this is a common situation. I'll comment on each
1) I don't understand the question because heat is heat not CO2 heat. You can calculate the heat of a reaction but it is to long to explain here
2) change in pH is pretty easy since if mixed in the correct amount all of the HCl is consumed. If not the calculations get pretty intense and too hard to explain here.
3) this depends on the amounts of each
4) Same as above since you know how much CO2 is given off you could calculate the pressure rise but you need to know more about the size of the vessel.
5) I am sure there is a way to do it but I can't think of it!

There are several ways to determine the characteristics of a chemical reaction, also known as reaction kinetics. These include measuring the rate of the reaction, observing changes in temperature, pressure, or pH, and tracking changes in the concentration or amount of reactants and products. In your example, the characteristics of the reaction between CaCO_3 and HCl can be determined by measuring the amount of CO_2 produced, the change in pH, the amount of CO_2 in relation to its volume, the change in concentration of reactants, the change in pressure, and the change in conductivity.

To determine these observations, common techniques include using spectrophotometry, titration, gas chromatography, and other analytical methods. These techniques allow scientists to accurately measure the various parameters of a chemical reaction and analyze the data to determine the characteristics of the reaction. It is important to note that the specific techniques used may vary depending on the reaction being studied and the resources available. Additionally, computer modeling can also be used to predict and analyze the characteristics of a chemical reaction.
