I don't know how else to describe it but I hope this helps. :)
Answer:
(A) It increases in temperature
Answer:
The NaCl concentration will be 0.03 M.
Explanation:
Given data:
Initial volume = V₁ = 56.98 mL (56.98/1000 = 0.05698 L)
Initial concentration = M₁= 0.5894 M
Final volume = V₂= 1.20 L
Final concentration = M₂= ?
Solution:
By diluting the solution volume of solution will increase while number of moles of solute remain the same.
Formula:
Initial concentration × Initial volume = Final concentration × Final volume
M₁V₁ = M₂V₂
M₂ = M₁V₁ / V₂
M₂ = 0.5894 M × 0.05698 L / 1.20 L
M₂ = 0.0336 M /1.20
M₂ = 0.03 M
Answer:
1148 grams
Explanation:
The balanced chemical reaction of this question is as follows:
2Al + 3Cl2 → 2AlCl3
Based on the equation above;
2 moles of Aluminum react to produce 2 moles of Aluminum chloride (AlCl3)
Therefore, 8.6 moles of aluminum will react to produce: 8.6 × 2/2
= 8.6moles of AlCl3.
Using mole = mass ÷ molar mass, to determine the number of grams.
Molar Mass of AlCl3 = 27 + 35.5(3)
= 27 + 106.5
= 133.5g/mol
Using mole = mass/molar mass
Mass = molar mass × mole
Mass = 133.5 × 8.6
Mass = 1148.1
Mass of AlCl3 = 1148 grams
