Step 3: Divide the number of moles of each element by the smallest number of moles. ...
Step 4: Convert numbers to whole numbers.
Answer:
D. Surface tension.
Explanation:
Surface tension is defined as the energy required to increase the surface area of a liquid by a unit amount.
The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:
A molecule in a liquid experiences cohesive forces with other molecules in all directions while molecules at the surface of a liquid experiences only net inward cohesive forces.
Volume= length•width•height
V=5•7•3
V= 105cm^3
The answer is 23.5° but I guess 23° is closest
