Which statement best describes a molecular formula?

a. a molecular formula gives only the position of atoms present in a molecule

b. a molecular formula gives only the number and kind of atoms present in a molecule

c. a molecular formula gives only the number and kind of atoms present in a molecule and shows how large each atom is.

d. a molecular formula gives only the size of the atoms present in a molecule.

B. A molecular formula gives only the number and kind of atoms present in a molecule

Explanation: A molecular formula is the chemical formula of a substance which gives the actual number of atoms of each element present in the substance. It tells nothing about the size and shape of the atoms contained in it.

Empirical formula gives the simplest ratio of the atoms of each element present in the substance.

For example : The molecular formula of benzene is which gives the actual number of atoms of each element present and the empirical formula of benzene is which gives the simplest ratio of atoms present in it.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
