Grade 11 Stoichiometry question

In summary, the problem is asking for the volume of CO2 produced in a reaction between 0.4 L of 0.6 M H3PO4 and 36 g of Na2CO3 at 333 K and 90 kPa. The solution involves using the reaction equation and calculating the moles of each substance, then using the ideal gas equation to determine the volume of CO2 produced at the given temperature and pressure.

Start with the reaction equation.
 
  • #3
Write the equations, see how many moles of CO2 will be produced, use some gas equation(maybe the perfect gas equation) to calculate how much volume that occupies at this pressure.

For the record - in English it is called the ideal gas equation.

Haha, true that. Translating things literally is bound to fail.
I also saw there's a difference in english, with perfect gases being these that do not change their cp and cv with temp/pressure.
 

1. What is stoichiometry?

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction.

2. How do you calculate stoichiometric ratios?

Stoichiometric ratios can be calculated by using the coefficients of the balanced chemical equation. The coefficients represent the molar ratios between reactants and products.

3. What is the difference between theoretical yield and actual yield?

Theoretical yield is the amount of product that is predicted to be formed based on stoichiometric calculations. Actual yield is the amount of product that is actually obtained in a reaction. The difference between the two is known as the percent yield.

4. How do you use stoichiometry to determine limiting reactants?

In stoichiometry, the limiting reactant is the reactant that is completely used up in a reaction. To determine the limiting reactant, you can compare the amount of moles of each reactant to the stoichiometric ratio in the balanced equation. The reactant with fewer moles is the limiting reactant.

5. Can stoichiometry be used for non-gaseous reactions?

Yes, stoichiometry can be used for any type of chemical reaction, not just gaseous reactions. The principles of stoichiometry, such as balancing equations and calculating molar ratios, can be applied to any type of reaction.
