<span>Answer: 0.00 meters
Solution:
Step 1: Define displacement
DISPLACEMENT = a vector quantity that describes "linear or angular distance in a given direction between a body or point and a reference position."
Step 2: Understand the question
Assumption 1: Assume that when the ant moves 4.25 meters from its origin to its nest, it is moving in a positive direction (on a graph you would draw a line along the x-axis from its origin to +4.25).
Assumption 2: Assume that when the ant "turns around...back to the source of food", it is moving back in the negative direction (towards the origin).
Step 3: Analyze the question
What is the distance between where the ant originally started and where it ended its journey?
The ant started and ended its journey in the same place.
While it traveled a distance of 8.52 meters (2 * 4.26 = 8.52), it's displacement is actually 0.00 meters (4.26 + (-4.26) = 0.00)
Therefore, the answer is 0.00 meters</span>
Answer:
1.58 102 mol
Explanation:
I just looked it up on Quizlet.
Carbon Dioxide + Oxygen Gas + Water + Sunlight Yields Glucose + Oxygen
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%
