Explanation:
Answer:
what problem?
Answer:
The correct answer is option c) water and salts
Explanation:
Organic compounds contain carbon and hydrogen bonds. Both nucleic acids and proteins contain these. Water (H2O) and salts (Ex:NaCl) do not.
The pair of compounds that can be classified as inorganic from the given options are water and salts. These lack a carbon-hydrogen bond, unlike nucleic acids and proteins, which are organic.
The pair of compounds that can be classified as inorganic are water and salts. Inorganic compounds are defined as compounds that do not contain a carbon-hydrogen bond, which makes them different from organic compounds. Both water (H2O) and salts, like table salt (NaCl), do not contain any carbon-hydrogen bonds, so they are considered inorganic compounds. On the other hand, nucleic acids and proteins are both complex structures that include carbon-hydrogen bonds, making them organic compounds.

Explanation:
Oxygen-16 and oxygen-18 differ in structure only in that oxygen-18 has two more neutrons in its nucleus than oxygen-16 has.
There are three known stable isotopes of oxygen (8O): 16O, 17O, and 18O. Radioactive isotopes ranging from 11O to 26O have also been characterized, all short-lived.

0.384 moles of atoms are in 5.00 g of ¹³C of isotope.
Moles of any substance will be calculate by dividing the given mass of the substance to the molar mass of that substance.
In the question given that:
Given mass of carbon = 5grams (because isotope of carbon is present ¹³C)
Molar mass of carbon = 13g/mol (because isotope of carbon is present ¹³C)
Moles of carbon = 5grams / 13g/mol
Moles = 0.384 moles
Hence, 0.384 moles is the required moles.
