For the production of 300 kg of sodium phosphate:
a) what the energy amount envolved in the reaction
b)what is the volum of the released gas
c)what the volum of the consumed phosphate acid, considering d=1,69g/ml
Thank so much, for who could help me!
You don't have enough information to answer part a. Do you have delta H formation tables? You could use them.
b. Now that I read the other parts of the problem you don't have an equation, you don't know the gas. What's the equation? What gas are is evolved?
Well, the equation is Na2Co3(s)+H3Po4(s)=>Na3Po4(s)+H2O(l)+CO2(g). I checked this other information. I do really need this big help here guys, please!
Here is a worked example of a stoichiometry problem. Just follow the steps.

To determine the energy involved in the reaction for the production of 300 kg of sodium phosphate, we need to know the specific reaction and its corresponding enthalpy change. If you can provide the balanced chemical equation for the reaction, I can assist you in calculating the energy involved.
Similarly, to determine the volume of the gas released, we need to know the balanced chemical equation and the stoichiometry of the reaction. This information allows us to determine the molar ratio between the gas and the reactant.
Lastly, to calculate the volume of the consumed phosphoric acid, we need the molar ratio between the acid and the sodium phosphate in the balanced chemical equation. Additionally, we need the density of the phosphoric acid to convert the mass into volume. You provided the density of the phosphoric acid as 1.69 g/ml, which we can use for the calculation.
Please provide the balanced chemical equation for the reaction so that I can guide you through the calculations for parts (a), (b), and (c).
