The mass is 5kg
I hope this helps
Answer: 1.
2. 3 moles of : 2 moles of
3. 0.33 moles of : 0.92 moles of
4. is the limiting reagent and is the excess reagent.
5. Theoretical yield of is 29.3 g
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
3 moles of require = 2 moles of
Thus 0.33 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 3 moles of give = 2 moles of
Thus 0.33 moles of give = of
Theoretical yield of
Thus 29.3 g of aluminium chloride is formed.
The change is that the piston gets hotter? (Theres more heat in it)
1st energy level can hold 2 electrons
2nd energy level can hold 8 electrons
3rd energy level can hold 8 or 18 electrons
Actually, it could indeed be the independent variable.
