Answer:
hi! I'm pretty sure your answer is solvent!
Explanation:
not 100% sure but I looked it up on google. solvent does the dissolving, solute is what is being dissolved, and a solution is the solvent + the solute. hope this helped!
Answer:
Initial Velocity is when movement begins. When a body is at rest, the initial velocity is at 0 m/s.
Explanation:
Initial Velocity is the velocity at time interval t = 0
8.05 g of CuSO₄ is the highest mass of crystals.
a) CuO(solid) + H₂SO₄(aqueous) → CuSO₄(aqueous) + H₂O(liquid)
Molecular weight,
CuO = 79 g
Molar weight of CuSO₄ = 159 g,
79 g of CuO reacted with H₂SO₄ 159 g to form CuSO₄.
∴ 4 g of CuO
= 159/79 × 4
= 8.05 g of CuSO₄
b) Percentage yield and Theoretical yield :
The Theoretical yield:
CuSO₄ of 159.6 g → CuSO₄.5H₂O of 249.5 g
8.05 g = 249.5 × 8.05 ÷ 159.6 = 12.58 g
And the percentage yield = Weight of the product ÷ Theoretical yield × 100
= 11.25 ÷ 12.58 × 100
= 89.42%
