HCl + NaOH --> NaCl + H2O.
In layman terms, salt and water are the products of this chemical reaction.
Result the solution is a basic because .. in there added a strong base.. naoh
We determine the limiting reactant by using the moles present in the equation and the actual moles.
According to equation, ratio of Fe₂O₃ : Al = 1 : 2
Actual moles of Fe₂O₃ = 187.3 / (56 x 2 + 16 x 3)
= 1.17
Actual moles of Al = 94.51 / 27
= 3.5
Fe₂O₃ is limiting. Fe₂O₃ required:
(moles Al)/2 = 3.5/2 = 1.75
Moles to be added = 1.75 - 1.17
= 0.58
Mass to be added = moles x Mr
= 0.58 x (56 x 2 + 16 x 3)
= 92.8 grams
Answer:
1.39x10⁻⁶ mol
Explanation:
First we <u>convert the gallon of juice to liters</u>:
Then we <u>calculate the mass of antimony that would be in 3.785 L</u>, using the <em>given concentration</em>:
- 44.7 μg/L * 3.785 L = 169.2 μg
Then we <u>convert mass into moles</u>, using the <em>molecular mass</em>:
- 169.2 μg ÷ 121.76 μg/μmol = 1.39 μmol
Finally we <u>convert μmol into mol</u>:
- 1.39 μmol = 1.39x10⁻⁶ mol
Answer:
Hydrogen, Helium, Neon, Argon, Krypton, Xenon, Chlorine, Fluorine, Bromine, Nitrogen, and Oxygen.
