The statement which is an inference is; "the velocity of the stream is greatest near the outside of a meander."
The scientific method involves observations, hypothesis, experimentation and inference. The inference is a conclusion arrived at after conducting an experiment.
Hence, an inference is not a futuristic statement or a prediction but a statement of fact as gathered through the scientific study. The statement which represents an inference among the options is; "the velocity of the stream is greatest near the outside of a meander."

Answer:
53.9%
Explanation:
The equation of the reaction is;
C4H6O3+C7H6O3→C9H8O4+C2H4O2
Number of moles of salicyclic acid reacted = 88.3 g/138.121 g/mol = 0.639 moles
1 mole of salicyclic acid yields 1 mole of aspirin
0.639 moles of salicyclic acid also yields 0.639 moles of asprin
Theoretical yield of asprin = 0.639 moles * 180.158 g/mol
Theoretical yield of asprin = 115.12 g
Percent yield = Actual yield/Theoretical yield * 100/1
Percent yield = 62.0 g/115.12 g * 100
Percent yield = 53.9%
B. New atoms are formed as products.
Ionization energy, also called ionization potential, in chemistry, the amount of energy required to remove an electron from an isolated atom or molecule.
