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.
