Select the correct answer. Which sentence is a scientific statement? A. There is a substance around us that cannot be detected.
B. Kids should go to school for 12 years. C. Experimentation is the best way to obtain knowledge. D. Unicorns once existed on Earth. E. There are no living things on the Moon.\
The correct answer is option E, that is, there are no living things on the moon.
Scientific knowledge is created via experimentation and methodical observation on measurable objective variables. Scientific knowledge is supported on evidence. The statement, that is, there are no living things on the moon, is a fact based on various scientific evidence. It is not based on personal beliefs, however, in direct observation of proof. Thus, it is the true sentence regarding a scientific statement.
The other statements exhibit no supporting evidence, thus, one cannot consider them as scientific.
Syn addition refers to the addition of two substituents on the same face or side of a double bond. This differed from anti addition which a occurs across opposite face of the double bond.
Hydrogenation, hydroboration and dihydroxylation all involve syn addition to the double bond, hence the answer chosen above.
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
