Which substances have atoms of the same element but different molecular structures?A. He(g) and Ne(g)
B. K(s) and Na(s)
C. O2(g) and O3(g)
D. P4(s) and S8(s)
Answers
Answer: Th correct answer is option C.
Explanation:
Atoms are the smallest unit of a chemical element.
An element is defined as the simplest substance which cannot be further divided.
A molecule is defined as the combination of two or more atoms of same or different elements.
Fro the given options, option 3 and 4 are the molecules, but Option 3 has the different number of atoms of same element. These molecules have different molecular structures.
is the oxygen gas and
is ozone.
Hence, the correct answer is option C.

Answer:
a. Chemical bonds.
Explanation:
Hello,
In this case, it is necessary to know that when two elements are not stable by their own they should bond with an other atom of the same element via chemical bonds whereby the valence electrons act as bridges connecting the atoms. Some examples are diatomic-gaseous hydrogen, oxygen, nitrogen, chlorine, iodine, fluorine and bromine. Moreover, such chemical bonding is represented by lines binding the elements as shown on the attached picture.
Best regards.

An example of commensalism is tick on a deer. Therefore, option A is correct.
What is commensalism ?
Another sort of symbiotic interaction is commensalism, in which one organism benefits and the other does not in any way suffer. Golden jackals will pursue tigers as they hunt in order to consume the tigers' leftovers.
The term "commensalism" is derived from the word "commensal," which in human social interaction refers to "eating at the same table," and which itself is derived through French from the Medieval Latin term "commensalis," which refers to "sharing a table," from the prefix com-, which means "together," and mensa, which refers to "table" or "meal."
The simplest definition of commensalism is that it is a form of symbiosis in which one organism gains while the other neither gains nor suffers harm. The three primary forms of commensalism are phoresy, metabiosis, and inquilinism.
Thus, option A is correct.

So, 5.9 x 10^-7 x F = 3 x 10^8
Rearranging the equation, we get:
F = (3 x 10^8)/(5.9 x 10^-7) = 5.08 x 10^14 Hz
