Answer:

12.3 moles of $AlCl_{3}$ are produced by reacting 18.4 moles of $BaCl_{2}$ .

Explanation:

Balanced reaction: $2AlPO_{4}+3BaCl_{2}\rightarrow 2AlCl_{3}+Ba_{3}(PO_{4})_{2}$

According to balanced equation:

3 molecules of $BaCl_{2}$ produce 2 molecules of $AlCl_{3}$

So $3N_{A}$ molecules of $BaCl_{2}$ produce $2N_{A}$ molecules of $AlCl_{3}$ ( $N_{A}$ is avogadro number).

We know 1 mol of molecule = $N_{A}$ number of molecules.

So 3 moles of $BaCl_{2}$ produce 2 moles of $AlCl_{3}$ .

Hence 18.4 moles of $BaCl_{2}$ produce $(\frac{2}{3}\times 18.4)$ moles of $AlCl_{3}$ or 12.3 moles of $AlCl_{3}$ .

What is a possible cause of a large percentage of error in an experiment where mgo is produced from the combustion of magnesium?

PilotLPTM [1.2K]

A possible cause of a large percentage of error in an experiment where MgO is produced from the combustion of magnesium would be not all of the Mg has completely reacted. <span>

Adding O2 to the reaction 6CO2 + 6H2O <---> C6H12O6 + 6O2, WHICH WAY WILL THE REACTION SHIFT?

Alex73 [517]

Increase in Oxygen shift the equilibrium towards reactant side.

<u>Explanation:</u>

6CO₂ + 6H₂O ⇄ C₆H₁₂O₆ + 6O₂

This is the reaction occurs in the photosynthesis of plants by means of sunlight. In this case, if the concentration of Oxygen increases or adding more oxygen to the product side will shift the equilibrium towards the reactant side according to the Le Chatlier's principle, which adjusts the equilibrium by itself for any changes that is increase or decrease in pressure, temperature or concentration of reactants or products.
